Detailed Description
Embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
With the increase of the number of the application programs with the recording function, an application scenario may occur in which a plurality of application programs need to record simultaneously, whereas in a conventional operating system, only one application program is allowed to record, and when another application program needs to record, the recording operation needs to be started after the recording operation is finished, which obviously cannot meet the needs of a user. With the development of an operating system, in an Android system, simultaneous recording of multiple applications can be supported by sharing a bottom-layer input device in an audioFlinger and simultaneously reading recording data from the input device, and sharing the input device requires that the multiple applications use the same audio parameters, and simultaneous recording cannot be realized for applications with different audio parameters.
In the application, after a recording instruction is received, no matter how many first audio parameters corresponding to the first application programs are, full recording data are acquired, and then the full recording data are processed based on the first audio parameters according to the requirements of each first application program, so that each first application program acquires the corresponding target recording data, and in the process, no matter whether the first audio parameters are the same, simultaneous recording of different application programs can be realized.
Referring to fig. 1, a flowchart of a recording method according to an embodiment of the present application is shown. The method may include the steps of:
In an embodiment, the first application program is a computer program for starting a recording process in the intelligent terminal system, and when the first application program needs to implement a recording function, a recording instruction is sent to the intelligent terminal system. It should be noted that, the mode for controlling the first application program to send the recording instruction may be a starting mode or a user command mode. The starting mode is that the first application program is started, namely a recording instruction is sent to the system, and the first application program needs to be recorded. Or the recording function is not directly started after the first application program is started, and a recording instruction needs to be sent based on an operation instruction of a user.
And 102, acquiring full recording data based on the recording instruction.
In one embodiment, the full amount of recording data is obtained in response to a recording instruction. The sound is a section of waveform signal, the waveform signal is recorded during recording, in the recording process, because of different recorded recording data of different audio parameters, the recording data with relatively more recorded waveform signals is extracted and processed to obtain the recording data with relatively less recorded waveform signals, in the embodiment, the full recording data refers to original recording data read from a bottom layer, the recording data meeting the requirements of the first audio parameters corresponding to each first application program can be obtained after the full recording data is extracted and processed, and the processing of the full recording data comprises channel conversion and resampling. Specifically, the full-volume recording data is data read from the bottom layer with a sampling rate of 48KHZ, a sampling depth of 16 bits, and a channel number of 8.
In an embodiment, in order to implement different functions, the audio parameters corresponding to the respective application programs may be different, and therefore when the first application program needs to record, the first audio parameters corresponding to the respective first application programs need to be determined, where the first audio parameters may be the same or different.
Specifically, the first audio parameter includes a channel parameter, an adoption rate and a sampling depth, wherein the channel parameter refers to the number of channels; the sampling rate is the number of samples extracted from continuous signals and forming discrete signals per second and is expressed by hertz (Hz); the sampling depth refers to how fine the sound intensity is recorded in the sampling. In a possible application scenario, a first application program A and a first application program B both send recording instructions to an intelligent terminal system, wherein first audio parameters corresponding to the first application program A are a sampling rate of 48KHz, a sampling depth of 16 bits and a binaural; the first audio parameters corresponding to the first application program B are a sampling rate of 48KHz, a sampling depth of 16 bits, and a channel number of 4, that is, the first application program a and the first application program B which have different first audio parameters need to be recorded simultaneously. It should be noted that, the first application program a and the first application program B do not need to send the recording instruction to the intelligent terminal system at the same time, and when the first application program a is recording, the intelligent terminal system receives the recording instruction of the first application program B, and because the recording of the first application program a is not finished, the first application program a and the first application program B still need to be recorded at the same time.
Specifically, the order of steps 102 and 103 is not limited, and step 102 and step 103 may be performed first, and then step 103 may be performed, or step 103 and then step 102 may be performed, or step 102 and step 103 may be performed simultaneously.
And step 104, acquiring target recording data corresponding to each first application program based on each first audio parameter and the full recording data, and returning each target recording data to each first application program.
In an embodiment, the full-scale recording data is processed according to each first audio parameter to obtain target recording data, wherein the audio parameter of the target recording data is the same as the first audio parameter of the corresponding first application program, and the number of the target recording data is the same as the number of the first application programs. For example, if the audio parameters corresponding to the full-volume recording data are 48KHz sampling rate, 16bit sampling depth and 8 channels, and the first audio parameters corresponding to the first application program a are 48KHz sampling rate, 16bit sampling depth and two channels, extracting the full-volume recording data, and extracting 2 channel data from the 8 channel data as the target recording data corresponding to the first application program a; and if the first audio parameters corresponding to the first application program B are the sampling rate of 48KHz, the sampling depth of 16 bits and the channel number of 4, extracting the full-volume recording data, extracting 4 channel data from 8 channel data to serve as target recording data corresponding to the second application program B, returning the target recording data A to the first application program A, and returning the target recording data B to the first application program B, so that simultaneous recording can be realized under the condition that the first audio parameters corresponding to the first application program A and the first application program B are different.
In summary, in the present application, after receiving the recording instruction, no matter how many first audio parameters corresponding to the first application are, the full-volume recording data is obtained from the bottom layer, and then, the full-volume recording data is processed based on the first audio parameters according to the requirements of each first application, so that each first application obtains the corresponding target recording data, and in this process, no matter whether the first audio parameters are the same, simultaneous recording of different applications can be achieved.
Referring to fig. 2, a flowchart of a recording method according to an embodiment of the present application is shown, where the method may include the following steps:
In an embodiment, the setting of the second audio parameter is used for acquiring the full-volume recording data in a subsequent process, and in order to meet the requirements of various different first audio parameters after resampling the full-volume recording data, the second audio parameter is set according to a maximum value corresponding to the audio parameter.
In a possible implementation manner, the maximum value corresponding to the audio parameter is the maximum value of each audio parameter that can be acquired by the recording device. For example, for a channel parameter as an audio parameter, if the maximum value that can be acquired by the sound recording device is 8 channels, the channel parameter in the second audio parameter is set to 8, and at this time, the requirement of all the first applications on the number of channels can be met.
In an embodiment, the audio parameter corresponding to the obtained full-volume recording data is the second audio parameter, that is, the maximum value among the audio parameters, so that the recording data meeting the first audio parameter can be obtained by extracting the full-volume recording data.
In one embodiment, the second application is a first application having the same corresponding first audio parameter as the second audio parameter. For example, the sampling rate of the second audio parameter is 48KHz, the sampling depth is 16bit, and the channel number is 8, the first audio parameter with the first application program is also 48KHz, the sampling depth is 16bit, and the channel number is 8, at this time, the acquired full-volume recording data can be directly used as the target recording data corresponding to the second application program without being processed.
In an embodiment, the third application is a first application having a first audio parameter different from a second audio parameter, and in order to meet a requirement of the third application, the full-scale recording data needs to be processed according to the first audio parameter corresponding to the third application, so that the audio parameter of the target recording data corresponding to the third application obtained after processing is the same as the first audio parameter.
In a possible implementation manner, if the audio parameter is a channel parameter, the extracting the full-volume recording data according to the first audio parameter to obtain the target recording data corresponding to the third application includes: and extracting channel data with front channel values in the full-volume recording data as target recording data corresponding to a third application program based on the channel values corresponding to the first audio parameters. For most of the application programs, the sampling depth and the sampling rate are the same, when the audio parameters are set, the channel parameters can be concerned, when the channel parameters corresponding to the third application program are different from the channel parameters corresponding to the full recording data, the channel parameters corresponding to the full recording data are more than the channel parameters corresponding to the third application program, so that the channel data of different paths of the full recording data are split, and the channel data with the number of the front channels are selected as the target recording data corresponding to the third application program. For example, if the number of channels corresponding to the full-volume recording data is 8 and the third application program corresponds to a binaural channel, the first 2 channel data of the full-volume recording data are taken as the target recording data of the third application program.
In a possible implementation manner, the extracting the full-volume recording data according to the first audio parameter to obtain the target recording data corresponding to the third application includes: and judging whether the first audio parameters corresponding to the third application program are the same, if a fourth application program with the same first audio parameters exists in the third application program, extracting the full-volume recording data once based on the first audio parameters, and acquiring target recording data corresponding to the fourth application program. That is, for the fourth application program with the same first audio parameter, the full-volume recording data can be extracted only once, and the full-volume recording data is prevented from being repeatedly processed based on the same first audio parameter.
In summary, the maximum value corresponding to the audio parameter is set as the second audio parameter, so that the obtained full-volume recording data can meet the requirement, and a precondition guarantee is provided for processing the full-volume recording data and obtaining different target recording data corresponding to different first applications. And judging the first audio parameter and the second audio parameter, and if the first audio parameter is the same as the second audio parameter, directly taking the full-volume recording data as the target recording data corresponding to the second application program, so that unnecessary processing on the full-volume recording data is avoided, and the acquisition efficiency of the recording data is improved.
As shown in fig. 3, a flowchart of a recording method provided in an embodiment of the present application is shown, and the method is applied to a car-mounted Android system, and may include the following steps:
In an embodiment, a plurality of applications having a recording function exist in the Android system of the car machine, and one or more first applications have sent a recording instruction to the Android system of the car machine. For example, a vehicle event data recorder and a voice recognition program exist in the Android system of the vehicle, wherein the first audio parameter corresponding to the vehicle event data recorder is 16KHz in sampling rate, 16bit in sampling depth and 2 in channel number, the first audio parameter corresponding to the voice recognition program is 16KHz in sampling rate, 16bit in sampling depth and 8 in channel number. When the automobile data recorder is started and voice recognition is required to be carried out by utilizing the voice recognition program, the first application programs with different first audio parameters are required to be recorded simultaneously.
In one embodiment, the Android operating system has an Audio Application frame Audio Application framework, an Audio Native frame Audio local framework, Audio Services and an Audio HAL hardware abstraction layer. Wherein, the Audio Application frame and the Audio Native frame comprise an Audio record responsible for acquiring the recording data; the Audio Services comprise an executor of an Audio Flinger Audio strategy and are responsible for management of input and output stream equipment and processing and transmission of pcm data; and the Audio HAL hardware abstraction layer is between Audio Services and kernel, is responsible for interaction between Audio and hardware equipment and is called by the Audio Flinger. Therefore, for the Android system of the vehicle machine, the full amount of recording data can be read from the audioFlinger in the AudioRecord. If the sampling rate and the sampling depth of the automobile data recorder and the voice recognition program in step 301 are the same, the maximum channel number recording data is read from the AudioFlinger as the full recording data, wherein the channel number corresponding to the full recording data is 8, the sampling rate is 48KHz, and the sampling depth is 16 bits.
For example, as shown in fig. 4, each frame of data of the full-volume recording data has 8 channels of data, and since the number of channels of the car recorder is configured as two channels, the first two channels of data in each frame of data are extracted to obtain the target recording data with a car recorder sampling rate of 16KHz, a sampling depth of 16 bits, and a number of channels of 2. As shown in fig. 5, since the voice recognition program needs 8 channels of recording data, which is the maximum value of the number of channels, the full amount of recording data with the number of channels being 8 read from the AudioFlinger is resampled to obtain the target recording data with the voice recognition program sampling rate being 16KHz, the sampling depth being 16 bits, and the number of channels being 8, and the target recording data is transmitted to the voice recognition program. That is to say, no matter how many channels the first application program corresponds to, the recording data with the largest number of channels is read from the AudioFlinger, and then the target recording data corresponding to the first application program is determined according to the number of channels corresponding to the first application program, so that the requirement that different channels of the first application program record simultaneously is met.
To sum up, regardless of the specific value of the first recording parameter corresponding to the first application, the full-volume recording data is obtained from the AudioFlinger, so that the recording data on the bottom layer can be read by using one input device, and then the target recording data corresponding to the first application is determined according to the first recording parameter corresponding to the first application, so as to meet the requirement of simultaneous recording of the first applications.
