A mobile terminal implementing various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in themselves. Thus, "module" and "component" may be used in a mixture.

The mobile terminal may be implemented in various forms. For example, the terminal described in the present invention may include a mobile terminal such as a mobile phone, a smart phone, a notebook computer, a digital broadcast receiver, a PDA (personal digital assistant), a PAD (tablet computer), a PMP (portable multimedia player), a navigation device, and the like, and a stationary terminal such as a digital TV, a desktop computer, and the like.

Fig. 1 illustrates a mobile terminal having various components, but it is to be understood that not all illustrated components are required to be implemented. More or fewer components may alternatively be implemented. Elements of the mobile terminal will be described in detail below.

The wireless communication unit 110 typically includes one or more components that allow radio communication between the mobile terminal 100 and a wireless communication system or network. For example, the wireless communication unit 110 may include at least one of a broadcast receiving module 111, a mobile communication module 112, a wireless internet module 113, a short-range communication module 114, and a location information module 115.

The broadcast receiving module 111 receives a broadcast signal and/or broadcast associated information from an external broadcast management server via a broadcast channel. The broadcast channel may include a satellite channel and/or a terrestrial channel. The broadcast management server may be a server that generates and transmits broadcast signalsAnd/or a server broadcasting the related information or a server receiving a previously generated broadcasting signal and/or broadcasting related information and transmitting it to the terminal. The broadcast signal may include a TV broadcast signal, a radio broadcast signal, a data broadcast signal, and the like. Also, the broadcast signal may further include a broadcast signal combined with a TV or radio broadcast signal. The broadcast associated information may also be provided via a mobile communication network, and in this case, the broadcast associated information may be received by the mobile communication module 112. The broadcast signal may exist in various forms, for example, it may exist in the form of an Electronic Program Guide (EPG) of Digital Multimedia Broadcasting (DMB), an Electronic Service Guide (ESG) of digital video broadcasting-handheld (DVB-H), and the like. The broadcast receiving module 111 may receive a signal broadcast by using various types of broadcasting systems. In particular, the broadcast receiving module 111 may receive a broadcast signal by using a signal such as multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcasting-handheld (DVB-H), forward link media (MediaFLO)^@) A digital broadcasting system of a terrestrial digital broadcasting integrated service (ISDB-T), etc. receives digital broadcasting. The broadcast receiving module 111 may be constructed to be suitable for various broadcasting systems that provide broadcast signals as well as the above-mentioned digital broadcasting systems. The broadcast signal and/or broadcast associated information received via the broadcast receiving module 111 may be stored in the memory 160 (or other type of storage medium).

The mobile communication module 112 transmits and/or receives radio signals to and/or from at least one of a base station (e.g., access point, node B, etc.), an external terminal, and a server. Such radio signals may include voice call signals, video call signals, or various types of data transmitted and/or received according to text and/or multimedia messages.

The wireless internet module 113 supports wireless internet access of the mobile terminal. The module may be internally or externally coupled to the terminal. The wireless internet access technology to which the module relates may include WLAN (wireless LAN) (Wi-Fi), Wibro (wireless broadband), Wimax (worldwide interoperability for microwave access), HSDPA (high speed downlink packet access), and the like.

The short-range communication module 114 is a module for supporting short-range communication. Some examples of short-range communication technologies include bluetooth^TMRadio Frequency Identification (RFID), infrared data association (IrDA), Ultra Wideband (UWB), zigbee^TMAnd so on.

The location information module 115 is a module for checking or acquiring location information of the mobile terminal. A typical example of the location information module is a GPS (global positioning system). According to the current technology, the GPS module calculates distance information and accurate time information from three or more satellites and applies triangulation to the calculated information, thereby accurately calculating three-dimensional current location information according to longitude, latitude, and altitude. Currently, a method for calculating position and time information uses three satellites and corrects an error of the calculated position and time information by using another satellite. In addition, the GPS module can calculate speed information by continuously calculating current position information in real time.

The a/V input unit 120 is used to receive an audio or video signal. The a/V input unit 120 may include a camera 121 and a microphone 122, and the camera 121 processes image data of still pictures or video obtained by an image capturing apparatus in a video capturing mode or an image capturing mode. The processed image frames may be displayed on the display unit 151. The image frames processed by the camera 121 may be stored in the memory 160 (or other storage medium) or transmitted via the wireless communication unit 110, and two or more cameras 1210 may be provided according to the construction of the mobile terminal. The microphone 122 may receive sounds (audio data) via the microphone in a phone call mode, a recording mode, a voice recognition mode, or the like, and can process such sounds into audio data. The processed audio (voice) data may be converted into a format output transmittable to a mobile communication base station via the mobile communication module 112 in case of a phone call mode. The microphone 122 may implement various types of noise cancellation (or suppression) algorithms to cancel (or suppress) noise or interference generated in the course of receiving and transmitting audio signals.

The user input unit 130 may generate key input data according to a command input by a user to control various operations of the mobile terminal. The user input unit 130 allows a user to input various types of information, and may include a keyboard, dome sheet, touch pad (e.g., a touch-sensitive member that detects changes in resistance, pressure, capacitance, and the like due to being touched), scroll wheel, joystick, and the like. In particular, when the touch pad is superimposed on the display unit 151 in the form of a layer, a touch screen may be formed.

The sensing unit 140 detects a current state of the mobile terminal 100 (e.g., an open or closed state of the mobile terminal 100), a position of the mobile terminal 100, presence or absence of contact (i.e., touch input) by a user with the mobile terminal 100, an orientation of the mobile terminal 100, acceleration or deceleration movement and direction of the mobile terminal 100, and the like, and generates a command or signal for controlling an operation of the mobile terminal 100. For example, when the mobile terminal 100 is implemented as a slide-type mobile phone, the sensing unit 140 may sense whether the slide-type phone is opened or closed. In addition, the sensing unit 140 can detect whether the power supply unit 190 supplies power or whether the interface unit 170 is coupled with an external device.

The interface unit 170 serves as an interface through which at least one external device is connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device having an identification module, an audio input/output (I/O) port, a video I/O port, an earphone port, and the like. The identification module may store various information for authenticating a user using the mobile terminal 100 and may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), a Universal Subscriber Identity Module (USIM), and the like. In addition, a device having an identification module (hereinafter, referred to as an "identification device") may take the form of a smart card, and thus, the identification device may be connected with the mobile terminal 100 via a port or other connection means. The interface unit 170 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal and the external device.

In addition, when the mobile terminal 100 is connected with an external cradle, the interface unit 170 may serve as a path through which power is supplied from the cradle to the mobile terminal 100 or may serve as a path through which various command signals input from the cradle are transmitted to the mobile terminal. Various command signals or power input from the cradle may be used as signals for recognizing whether the mobile terminal is accurately mounted on the cradle. The output unit 150 is configured to provide output signals (e.g., audio signals, video signals, alarm signals, vibration signals, etc.) in a visual, audio, and/or tactile manner. The output unit 150 may include a display unit 151, an audio output module 152, and the like.

The display unit 151 may display information processed in the mobile terminal 100. For example, when the mobile terminal 100 is in a phone call mode, the display unit 151 may display a User Interface (UI) or a Graphical User Interface (GUI) related to a call or other communication (e.g., text messaging, multimedia file downloading, etc.). When the mobile terminal 100 is in a video call mode or an image capturing mode, the display unit 151 may display a captured image and/or a received image, a UI or GUI showing a video or an image and related functions, and the like.

Meanwhile, when the display unit 151 and the touch pad are overlapped with each other in the form of a layer to form a touch screen, the display unit 151 may serve as an input device and an output device. The display unit 151 may include at least one of a Liquid Crystal Display (LCD), a thin film transistor LCD (TFT-LCD), an Organic Light Emitting Diode (OLED) display, a flexible display, a three-dimensional (3D) display, and the like. Some of these displays may be configured to be transparent to allow a user to view from the outside, which may be referred to as transparent displays, and a typical transparent display may be, for example, a TOLED (transparent organic light emitting diode) display or the like. Depending on the particular desired implementation, the mobile terminal 100 may include two or more display units (or other display devices), for example, the mobile terminal may include an external display unit (not shown) and an internal display unit (not shown). The touch screen may be used to detect a touch input pressure as well as a touch input position and a touch input area.

The audio output module 152 may convert audio data received by the wireless communication unit 110 or stored in the memory 160 into an audio signal and output as sound when the mobile terminal is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Also, the audio output module 152 may provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output module 152 may include a speaker, a buzzer, and the like.

The memory 160 may store software programs and the like for processing and controlling operations performed by the controller 180, or may temporarily store data (e.g., a phonebook, messages, still images, videos, and the like) that has been or will be output. Also, the memory 160 may store data regarding various ways of vibration and audio signals output when a touch is applied to the touch screen.

The controller 180 generally controls the overall operation of the mobile terminal. For example, the controller 180 performs control and processing related to voice calls, data communications, video calls, and the like. In addition, the controller 180 may include a multimedia module 181 for reproducing (or playing back) multimedia data, and the multimedia module 181 may be constructed within the controller 180 or may be constructed separately from the controller 180. The controller 180 may perform a pattern recognition process to recognize a handwriting input or a picture drawing input performed on the touch screen as a character or an image.

The power supply unit 190 receives external power or internal power and provides appropriate power required to operate various elements and components under the control of the controller 180.

The software codes may be implemented by software applications (or programs) written in any suitable programming language, which may be stored in the memory 160 and executed by the controller 180.

Up to this point, mobile terminals have been described in terms of their functionality. Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.

A communication system in which a mobile terminal according to the present invention is operable will now be described with reference to fig. 2.

Such communication systems may use different air interfaces and/or physical layers. For example, the air interface used by the communication system includes, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (in particular, Long Term Evolution (LTE)), global system for mobile communications (GSM), and the like. By way of non-limiting example, the following description relates to a CDMA communication system, but such teachings are equally applicable to other types of systems.

Referring to fig. 2, the CDMA wireless communication system may include a plurality of mobile terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC280 is also configured to interface with a BSC275, which may be coupled to the base station 270 via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that a system as shown in fig. 2 may include multiple BSCs 2750.

Each BS270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz,5MHz, etc.).

The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each sector of a particular BS270 may be referred to as a plurality of cell sites.

As shown in fig. 2, a Broadcast Transmitter (BT)295 transmits a broadcast signal to the mobile terminal 100 operating within the system. A broadcast receiving module 111 as shown in fig. 1 is provided at the mobile terminal 100 to receive a broadcast signal transmitted by the BT 295. In fig. 2, several Global Positioning System (GPS) satellites 300 are shown. The satellite 300 assists in locating at least one of the plurality of mobile terminals 100.

In fig. 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning information may be obtained with any number of satellites. The location information module 115 as shown in fig. 1 is generally configured to cooperate with satellites 300 to obtain desired positioning information, and a typical example of the location information module 115 is GPS. Other techniques that can track the location of the mobile terminal may be used instead of or in addition to GPS tracking techniques. In addition, at least one GPS satellite 300 may selectively or additionally process satellite DMB transmission.

As a typical operation of the wireless communication system, the BS270 receives reverse link signals from various mobile terminals 100. The mobile terminal 100 is generally engaged in conversations, messaging, and other types of communications. Each reverse link signal received by a particular base station 270 is processed within the particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC provides call resource allocation and mobility management functions including coordination of soft handoff procedures between BSs 270. The BSCs 275 also route the received data to the MSC280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS270 to transmit forward link signals to the mobile terminal 100.

Based on the hardware structure of the mobile terminal and the communication system, the invention provides a noise positioning device.

As shown in fig. 3, fig. 3 is a schematic diagram of an energy module of the noise positioning device according to the first embodiment of the present invention.

In this embodiment, the noise localization apparatus includes: the device comprises a first judging module 01, a first obtaining module 02, a first output module 03 and a first audition module 04.

The first judging module 01 is configured to judge whether the terminal receives an audio track processing data output instruction when playing an audio file;

in this embodiment, the terminal is a device equipped with a media player, and when a user uses the media player in the terminal to play an audio file, the user finds that the audio file played by the terminal has a noise, and at this time, the user may stop playing the audio file and return to a playing start point of the audio file or a playing node where the user primarily thinks that the noise has occurred to play the audio file again, and when playing the audio file, the first determining module 01 determines whether a track processing data output instruction triggered by the user is received, and the track processing data output instruction may enable the terminal to output data for track processing of the audio file in an audiotrack processing link.

It should be noted that the scheme is applicable to terminals of an Android system, terminals of a Windows system, and terminals of an ISO system.

The first obtaining module 02 is configured to, when an output instruction of the audio track processing data is detected, obtain audio track processing data corresponding to a current playing node of the audio file by the terminal, where the audio track processing data includes the audio file of the current playing node and data for performing audio track processing on the audio file of the current playing node by the terminal;

when detecting an audio track processing data output instruction triggered by a user, the first obtaining module 02 obtains audio track processing data corresponding to a current playing node of an audio file by a terminal, where the audio track processing data can be understood as audio track processing data in an audiotrack processing link, and the audio track processing data includes the audio file of the current playing node and data for performing audio track processing on the audio file of the current playing node by the terminal. For example, in the process of playing an audio file, in order to make the timbre of the played sound have no noise, the terminal performs audiotrack processing on the audio file in real time, and when an output instruction of audio track processing data triggered by a user is detected, acquires audio track processing data corresponding to a currently played node of the audio file. When the audio track processing data output instruction is detected, the audio track processing data are acquired in real time until the audio track processing data output closing instruction is detected.

How this is achieved is specified below by way of example one.

When the audio file is played for 10 seconds, detecting an output instruction of the audio track processing data, starting to acquire the audio track processing data corresponding to the 10-second playing node of the audio file, acquiring the audio track processing data corresponding to the playing node in real time in the playing process of the audio file, when the audio file is played for 31 seconds, detecting an output closing instruction of the audio track processing data, stopping acquiring the audio track processing data corresponding to the 31-second playing node of the audio file, and acquiring 20 seconds of audio track processing data in the time period from 10 seconds to 31 seconds.

The first output module 03 is configured to output the audio track processing data to a corresponding first audio listening trial file, and store the first audio listening trial file;

when audio track processing data corresponding to the audio file current playing node of the terminal is acquired, the first output module 03 calls an outputAudioData () function in a public dynamic library libdumpaudio.so in the terminal to output the audio track processing data, writes the audio track processing data into a corresponding first audio audition file through an audiotrack interface and a dumpAudioPostProccessPcm function, and stores the first audio audition file in the terminal. Wherein the track processing data is output in real time until an output closing instruction of the track processing data is detected, that is, when the output closing instruction of the track processing data is detected, the output of the track processing data is stopped.

The first audition module 04 is configured to play a first audio audition file when detecting the first audition instruction, so as to determine whether there is a noise in the audio track processing data in the first audio audition file.

When a user wants to listen to the first audio trial listening file in an trial manner to judge whether the first audio trial listening file has noise in the playing process, triggering a first trial listening instruction, when the first trial listening instruction is detected, playing the first audio trial listening file through a first trial listening module 04 in the terminal, and in the process of listening the first audio trial listening file by the user, if the track processing data in the first audio trial listening file has the noise, indicating that the audio track processing link has the noise, further indicating that an algorithm corresponding to the audio track processing link in the terminal-integrated audio processing algorithm has a problem, such as the track adjusting parameter or the logic is incorrect, and modifying the track adjusting parameter or the logic by the user at the moment so that the audio track processing link cannot have the noise; if the track processing data in the first audio trial listening file does not have the noise, the fact that the noise does not occur in the audiotrack processing link is indicated, and the result is normal.

It can be understood that, in order to increase the atmosphere of sound and make the sound smoother during the playing of the audio file, the terminal further needs to perform audio mixing processing and audio post-processing on the audio mixing processing, where the audio mixing processing is associated with the audiolinger mixing processing link, and the audio post-processing is associated with the audiohal audio post-processing link. When a detected audio mixing processing data instruction is detected, audio mixing processing data of an audio file at a current playing node is obtained and output, when an audio post-processing data output instruction is detected, audio post-processing data of the audio file at the current playing node is obtained and output, namely when an audio track processing data output instruction, an audio mixing processing data instruction and an audio post-processing data output instruction are detected at the current playing node of the audio file at the same time, audio track processing data, audio mixing processing data and audio post-processing data corresponding to the current playing node are obtained and output at the same time, and in the process of obtaining and outputting the three data, the obtaining and the output of one data cannot influence the other two data.

In addition, it should be noted that, from the beginning to the end of playing an audio file, the file size of the audio file is not changed during the playing process, but the audio file is adjusted by the terminal-integrated sound effect processing algorithm based on the corresponding sound effect processing parameters generated by the audio file, so that the played sound is changed.

In this embodiment, when an audio file is played, if an output instruction of audio track processing data is detected, audio track processing data corresponding to a current playing node of the audio file by a terminal is acquired, the acquired audio track processing data is output to a corresponding first audio audition file, and the first audio audition file is stored, so that the audio processing data corresponding to a sound effect processing link is output; after a user obtains audio processing data corresponding to the audio processing link, namely a first audio audition file, the first audio audition file can be further played to determine whether the audio track processing data in the first audio audition file has noise, so that the link of the audio with the noise is positioned, and the efficiency of processing the audio effect is improved.

Further, based on the first embodiment, a second embodiment of the noise localization apparatus of the present invention is provided, and in this embodiment, referring to fig. 4, the noise localization apparatus further includes: the first receiving module 05, the second playing module 06, the second obtaining module 07, the second outputting module 08, and the second listening trial module 09.

the second obtaining module 07 is configured to obtain audio mixing processing data of the audio file at the current playing node, where the audio mixing processing data includes the audio file of the current playing node and data for performing mixing processing on the audio file of the current playing node by the terminal;

when an audio mixing processing data output instruction triggered by a user is detected, the second playing module 06 returns to the current playing node according to the first audition result, and plays an audio file of the current playing node, the second obtaining module 07 obtains audio mixing processing data of the audio file at the current playing node, and the audio mixing processing data can be understood as mixing processing data in an audiolinger mixing processing link, wherein the audio mixing processing data includes the audio file of the current playing node and data for performing mixing processing on the audio file of the current playing node by the terminal. For example, in the process of playing an audio file, in order to increase the atmosphere of the played sound, the terminal performs audiolinger mixing processing on the audio file in real time, and when an audio mixing processing data output instruction triggered by a user is detected, audio mixing processing data of the audio file at the current playing node is acquired. When an audio mixing processing data output instruction triggered by a user is detected, audio mixing processing data are acquired in real time, and the corresponding terminal can automatically stop acquiring the audio mixing processing data at a playing node where audio track processing data acquisition is stopped.

How this scheme is implemented is specifically described by the second example.

With reference to the first example, when an audio mixing processing data output instruction is detected, the audio file is returned to the playing node that plays the audio file for 10 seconds to play, audio mixing processing data corresponding to the 10-second playing node of the audio file is acquired at the same time, and the audio mixing processing data corresponding to the playing node is acquired in real time during the playing process of the audio file, when the audio file is played for 31 seconds, the terminal can automatically stop acquiring the audio mixing processing data, and then 20 seconds of audio mixing processing data are acquired in the time period from 10 seconds to 31 seconds.

Or, when an audio mixing processing data output instruction triggered by a user is detected, acquiring the audio mixing processing data in real time, and when an audio mixing processing data output closing instruction is detected in the acquiring process, stopping acquiring the audio mixing processing data.

The second output module 08 is configured to output the audio mixing processing data to a corresponding second audio listening trial file, and store the second audio listening trial file;

when audio mixing processing data corresponding to the current playing node of the audio file at the terminal is acquired, the second output module 08 calls an outputAudioData () function in a public dynamic library libdump audio.so in the terminal to output the audio mixing processing data, writes the audio mixing processing data into a corresponding second audio listening trial file through an audiotrack interface and a dump audio post process sccm function, and stores the second audio listening trial file in the terminal. Wherein the audio mixing processing data is output in real time until the terminal automatically stops outputting or until an audio mixing processing data output closing instruction is detected.

The second audition module 09 is configured to play a second audio audition file when the second audition instruction is detected, so as to determine whether there is a noise in the audio mixing processing data in the second audio audition file.

When a user wants to audition the second audio audition file to judge whether the second audio audition file has noise in the playing process, triggering a second audition instruction, when the second audition instruction is detected, playing the second audio audition file through a second audition module 09 in the terminal, and in the process that the user audits the second audio audition file, if noise exists in audio mixing processing data in the second audio audition file, indicating that the noise occurs in an audiomixer processing link, and further indicating that an algorithm corresponding to the audiomixer processing link in a terminal-integrated audio processing algorithm has a problem, such as the audio mixing adjusting parameter or logic is incorrect, at the moment, the user can modify the audio mixing adjusting parameter or logic, so that the audiomixer processing link cannot have noise; if the audio mixing processing data in the second audio trial listening file does not have noise, it indicates that the noise does not occur in the audiolinger mixing processing link and the audio mixing processing data is normal.

In this embodiment, when it is determined that no noise occurs in audio track processing data in a first audio listening file, a first listening trial result fed back by a user is received, and when an audio mixing processing data output instruction is detected, the current playing node is returned according to the first listening trial result, and an audio file of the current playing node is played; then, audio mixing processing data of the audio file at the current playing node is obtained, the audio mixing processing data is output to a corresponding second audio listening trial file, and the second audio listening trial file is stored; the user can further play the second audio listening trial file to determine whether the audio mixing processing data in the second audio listening trial file has noise, so that the link of the noise occurring in the audio is positioned, and the efficiency of processing the audio effect is improved.

The second receiving module 10 is configured to receive a second audition result fed back by the user when the audio mixing processing data in the second audio audition file does not generate a noise;

in this embodiment, after the user audits the second audio audition file, if it is found that the audio mixing processing data in the second audio audition file does not generate a noise, a second audition result of the audio mixing processing data corresponding to the current playing node, where the audio file does not generate a noise, is fed back to the terminal, and a second receiving module 10 in the terminal receives the second audition result fed back by the user.

The third playing module 20 is configured to, when an audio post-processing data output instruction is detected, return to a current playing node according to a second audition result, and play an audio file of the current playing node;

the third obtaining module 30 is configured to obtain audio post-processing data of the audio file at the current playing node, where the audio post-processing data includes the audio file of the current playing node and data for performing post-sound effect processing on the audio file of the current playing node by the terminal;

when an audio post-processing data output instruction triggered by a user is detected, the third playing module 20 returns to the current playing node according to the second audition result, the third acquiring module 30 plays an audio file of the current playing node, and acquires audio post-processing data of the audio file at the current playing node, where the audio post-processing data can be understood as post-audio processing data in an audio post-processing link, where the audio post-processing data includes the audio file of the current playing node and data for performing post-audio processing on the audio file of the current playing node by the terminal. For example, in the process of playing an audio file, in order to make the played sound smoother, the terminal performs audio post-processing, such as noise reduction, on the audio file in real time, and when an audio post-processing data output instruction triggered by a user is detected, acquires audio post-processing data of the audio file at a current playing node. When an audio post-processing data output instruction triggered by a user is detected, audio post-processing data are acquired in real time, and the corresponding terminal can automatically stop acquiring the audio post-processing data at a playing node where the acquisition of the audio track processing data stops.

How this is achieved is specifically illustrated by example three below.

With the first example, when an audio post-processing data output instruction is detected, the audio file is returned to the playing node which plays the audio file for 10 seconds to play, meanwhile, audio post-processing data corresponding to the audio file playing node at the 10 seconds is acquired by the terminal, and the audio post-processing data corresponding to the playing node is acquired in real time in the playing process of the audio file, when the audio file is played for 31 seconds, the terminal can automatically stop acquiring the audio post-processing data, so that 20 seconds of audio post-processing data are acquired in the time period from 10 seconds to 31 seconds.

Or when an audio post-processing data output instruction triggered by a user is detected, the audio post-processing data is acquired in real time, and when an audio post-processing data output closing instruction is detected in the acquisition process, the acquisition of the audio post-processing data is stopped.

The third output module 40 is configured to output the audio post-processing data to a corresponding third audio listening file, and store the third audio listening file;

when audio post-processing data corresponding to the current playing node of the audio file at the terminal is acquired, the third output module 40 calls an outputAudioData () function in a public dynamic library libdump audio.so in the terminal to output the audio post-processing data, writes the audio post-processing data into a corresponding third audio audition file through an audiotrack interface and a dump audio postprocess sccm function, and stores the third audio audition file in the terminal. Wherein the audio post-processing data is output in real time until the terminal automatically stops outputting or until an audio post-processing data output closing instruction is detected.

The third audition module 50 is configured to play a third audio audition file when detecting a third audition instruction, so as to determine whether there is a noise in the audio post-processing data in the third audio audition file.

When a user wants to listen to the third audio trial listening file in an trial manner to judge whether the third audio trial listening file has noise in the playing process, triggering a third trial listening instruction, when the third trial listening instruction is detected, playing the third audio trial listening file through a third trial listening module 50 in the terminal, and in the process of listening the third audio trial listening file by the user, if the audio post-processing data in the third audio trial listening file has the noise, indicating that the audio post-processing link of the audiohal has the noise, further indicating that an algorithm corresponding to the audiohal post-processing link in the audio processing algorithm integrated by the terminal has a problem, and if the post-audio adjusting parameter or logic is incorrect, modifying the post-audio adjusting parameter or logic by the user so that the audiohal post-processing link can not have the noise; and if the audio post-processing data in the third audio audition file does not have the noise, indicating that the audio post-processing link does not have the noise and is normal.

In this embodiment, when it is determined that the audio mixing processing data in the second audio listening trial file does not have noise, a second listening trial result fed back by the user is received; when an audio post-processing data output instruction is detected, returning to the current playing node according to a second audition result, and playing an audio file of the current playing node; then, audio post-processing data of the audio file at the current playing node is obtained, the audio post-processing data is output to a corresponding third audio audition file, and the third audio audition file is stored; the user can further play the third audio listening trial file to determine whether the data of the later audio processing in the third audio listening trial file has noise, so that the link of the audio with the noise is positioned, and the efficiency of processing the audio is improved.

Further, based on any one of the above embodiments, a fourth embodiment of the noise localization apparatus of the present invention is provided, and in this embodiment, referring to fig. 6, the noise localization apparatus further includes: a second determination module 60, and a stop module 70.

The second judging module 60 is configured to judge whether the terminal receives an audio processing data closing instruction when the audio file is played;

the stopping module 70 is configured to stop playing the audio file when it is determined that the terminal receives the audio processing data closing instruction.

In this embodiment, the audio processing data closing command can control the terminal to simultaneously stop outputting the track processing data, the audio mixing processing data and the audio post-processing data, for example, if the terminal simultaneously outputs the track processing data, the audio mixing processing data and the audio post-processing data during the playing of the audio file, the second determining module 60 detects the user-triggered audio processing data closing command, and the call stopping module 70 stops outputting the track processing data, the audio mixing processing data and the audio post-processing data and stops playing the audio file.

In addition, when the audio file is played, if the audio processing data opening instruction triggered by the user is not detected, even if the audio track processing data output instruction, the audio mixing processing data output instruction and the audio post-processing data output instruction triggered by the user are detected, one or more of the three instructions do not output data.

The terminal of the embodiment simultaneously outputs the audio track processing data, the audio mixing processing data and the audio post-processing data in the playing process of the audio file, and the user can input an instruction for stopping all data output so as to stop outputting the audio track processing data, the audio mixing processing data and the audio post-processing data.

In this embodiment, after detecting the output instruction of the audio track processing data, the third determining module 80 determines whether a fourth audio trial listening file is stored in the terminal, and if the fourth audio trial listening file is stored in the terminal, the deleting module 90 calls clearpreaudiodadata () in the public dynamic library libdumpoudio so to clear the fourth audio trial listening file which is stored in the memory of the terminal and is longer than a preset time from the current time, for example, clear the fourth audio trial listening file which is longer than 1 day from the current time.

The storage space allocated to the audio audition file by the terminal of the embodiment is limited, and a plurality of audio audition files can be repeatedly output in the process of positioning the sound effect processing link of the noise occurring in the audio, so that the storage space may be insufficient, and in order to avoid that the audio audition files stored before may interfere with the currently output audio audition files, the storage space of the terminal needs to be initialized, so that the storage resource is saved.

The invention further provides various embodiments of the noise positioning method.

Referring to fig. 8, fig. 8 is a flowchart illustrating a noise localization method according to a first embodiment of the present invention.

Step S01, when playing audio file, judging whether the terminal receives the output command of audio track processing data;

in this embodiment, when a user finds that a noise occurs in an audio file played by a terminal when the user plays the audio file using a media player in the terminal, at this time, the user may stop playing the audio file, and return to a playing start point of the audio file or a playing node where the user primarily thinks that the noise occurs to play the audio file again.

Step S02, when detecting the output instruction of the audio track processing data, acquiring the audio track processing data corresponding to the audio file current playing node by the terminal, wherein the audio track processing data comprises the audio file of the current playing node and the data for the audio file of the current playing node to perform audio track processing by the terminal;

For example, in the process of playing an audio file, in order to make the timbre of the played sound have no noise, the terminal performs audiotrack processing on the audio file in real time, and when an output instruction of audio track processing data triggered by a user is detected, acquires audio track processing data corresponding to a currently played node of the audio file. When the audio track processing data output instruction is detected, the audio track processing data are acquired in real time until the audio track processing data output closing instruction is detected.

How this is achieved is specified below by way of example one.

Step S03, outputting the audio track processing data to the corresponding first audio frequency audition file, and saving the first audio frequency audition file;

when audio track processing data corresponding to a current playing node of an audio file of a terminal is obtained, an outputAudioData () function in a public dynamic library libdumpaudio.so in the terminal is called to output the audio track processing data, the audio track processing data is written into a corresponding first audio audition file through an audiotrack interface and a dumpaudiopostprocessupcm function, and the first audio audition file is stored in the terminal. Wherein the track processing data is output in real time until an output closing instruction of the track processing data is detected, that is, when the output closing instruction of the track processing data is detected, the output of the track processing data is stopped.

In step S04, when the first audition instruction is detected, the first audio audition file is played to determine whether there is a noise in the audio track processing data in the first audio audition file.

Step S06, when an audio mixing processing data output instruction is detected, returning to the current playing node according to the first audition result, and playing the audio file of the current playing node;

step S07, acquiring audio mixing processing data of the audio file at the current playing node, wherein the audio mixing processing data comprises the audio file of the current playing node and data for performing mixing processing on the audio file of the current playing node by the terminal;

For example, in the process of playing an audio file, in order to increase the atmosphere of the played sound, the terminal performs audiolinger mixing processing on the audio file in real time, and when an audio mixing processing data output instruction triggered by a user is detected, audio mixing processing data of the audio file at the current playing node is acquired. When an audio mixing processing data output instruction triggered by a user is detected, audio mixing processing data are acquired in real time, and the corresponding terminal can automatically stop acquiring the audio mixing processing data at a playing node where audio track processing data acquisition is stopped.

How this scheme is implemented is specifically described by the second example.

Step S08, outputting audio mixing processing data to a corresponding second audio listening trial file, and storing the second audio listening trial file;

when audio mixing processing data corresponding to the current playing node of the audio file of the terminal is obtained, an outputAudioData () function in a public dynamic library libdumpaudio.so in the terminal is called to output the audio mixing processing data, the audio mixing processing data is written into a corresponding second audio audition file through an audiorack type interface and a dumpaudiopostaccesspcm function, and the second audio audition file is stored in the terminal. Wherein the audio mixing processing data is output in real time until the terminal automatically stops outputting or until an audio mixing processing data output closing instruction is detected.

Step S09, when the second audio trial listening instruction is detected, playing a second audio trial listening file to determine whether there is a noise in the audio mixing processing data in the second audio trial listening file.

Further, referring to fig. 10 based on the second embodiment, a flowchart of a third embodiment of the noise localization method according to the present invention is shown, in which after step S09, the noise localization method further includes:

step S10, when the audio mixing processing data in the second audio trial listening file has no noise, receiving a second trial listening result fed back by the user;

in this embodiment, after the user audits the second audio audition file, if it is found that the audio mixing processing data in the second audio audition file does not have a noise, a second audition result of the audio mixing processing data corresponding to the current playing node, where the audio file does not have a noise, is fed back to the terminal, and the terminal receives the second audition result fed back by the user.

Step S20, when an audio post-processing data output instruction is detected, returning to the current playing node according to a second audition result, and playing an audio file of the current playing node;

step S30, acquiring audio post-processing data of the audio file at the current playing node, wherein the audio post-processing data comprises the audio file of the current playing node and data for performing post sound effect processing on the audio file of the current playing node by the terminal;

when an audio post-processing data output instruction triggered by a user is detected, returning the current playing node according to the second audition result, playing an audio file of the current playing node, and acquiring audio post-processing data of the audio file at the current playing node, wherein the audio post-processing data can be understood as post-audio processing data in an audio hal audio post-processing link, and comprises the audio file of the current playing node and data for performing post-audio processing on the audio file of the current playing node by the terminal. For example, in the process of playing an audio file, in order to make the played sound smoother, the terminal performs audio post-processing, such as noise reduction, on the audio file in real time, and when an audio post-processing data output instruction triggered by a user is detected, acquires audio post-processing data of the audio file at a current playing node. When an audio post-processing data output instruction triggered by a user is detected, audio post-processing data are acquired in real time, and the corresponding terminal can automatically stop acquiring the audio post-processing data at a playing node where the acquisition of the audio track processing data stops.

How this is achieved is specifically illustrated by example three below.

Step S40, outputting the audio post-processing data to a corresponding third audio listening file, and saving the third audio listening file;

when audio post-processing data corresponding to the current playing node of the audio file of the terminal is obtained, an outputAudioData () function in a public dynamic library libdumpoudio.so in the terminal is called to output the audio post-processing data, the audio post-processing data is written into a corresponding third audio audition file through an audiorack interface and a dumpaudiopostprocesspcm function, and the third audio audition file is stored in the terminal. Wherein the audio post-processing data is output in real time until the terminal automatically stops outputting or until an audio post-processing data output closing instruction is detected.

Step S50, when the third audio trial listening instruction is detected, playing the third audio trial listening file to determine whether there is a noise in the audio post-processing data in the third audio trial listening file.

When a user wants to audition the third audio audition file to judge whether the third audio audition file has noise in the playing process, triggering a third audition instruction, when the third audition instruction is detected, playing the third audio audition file through the terminal, and in the process that the user audits the third audio audition file, if the audio post-processing data in the third audio audition file has noise, indicating that the audio post-processing link has noise, and further indicating that an algorithm corresponding to the audio post-processing link of the audiohal in the terminal-integrated audio processing algorithm has a problem, such as the post-audio adjusting parameter or logic is incorrect, at the moment, the user can modify the post-audio adjusting parameter or logic, so that the audio post-processing link of the audiohal cannot have noise; and if the audio post-processing data in the third audio audition file does not have the noise, indicating that the audio post-processing link does not have the noise and is normal.

Further, referring to fig. 11 based on any of the above embodiments, a flowchart of a fourth embodiment of the noise localization method according to the present invention is shown, in which after step S50, the noise localization method further includes:

step S60, when playing audio file, judging whether the terminal receives audio processing data closing instruction;

in step S70, when it is determined that the terminal receives the audio processing data closing instruction, the playing of the audio file is stopped.

In this embodiment, the audio processing data closing command can control the terminal to simultaneously stop outputting the track processing data, the audio mixing processing data and the audio post-processing data, for example, if the terminal simultaneously outputs the track processing data, the audio mixing processing data and the audio post-processing data during the playing of the audio file, when the audio processing data closing command triggered by the user is detected, the output of the track processing data, the audio mixing processing data and the audio post-processing data is stopped, and the playing of the audio file is stopped.
