It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
According to an aspect of the embodiments of the present invention, there is provided an audio transmission method, optionally, as an optional implementation manner, as shown in fig. 1, the audio transmission method includes:
s102, after a recording device is started, in the process of recording audio by the recording device, acquiring the audio recorded by the recording device in real time;
s104, determining the audio with the preset duration as an original audio file under the condition that the duration of the acquired audio reaches the preset duration;
s106, after the original audio file is obtained, deleting noise data in the original audio file, and performing encryption operation on the original audio file to obtain a first audio file;
and S108, sending the first audio file to a receiving party.
Optionally, the audio transmission method may be applied, but not limited to, to a terminal capable of calculating data, such as a mobile phone, a tablet computer, a notebook computer, a PC, or the like, or to an intelligent device, such as an intelligent tablet, an intelligent recording device, or the like. The terminal or the smart device may interact with the server through a network, which may include, but is not limited to, a wireless network or a wired network. Wherein, this wireless network includes: WIFI and other networks that enable wireless communication. Such wired networks may include, but are not limited to: wide area networks, metropolitan area networks, and local area networks. The server may include, but is not limited to, any hardware device capable of performing computations.
Alternatively, the above audio transmission method may be applied, but not limited, to the field of audio encryption transmission. By taking audio encryption transmission as an example, after the recording equipment is started, the recording equipment starts to record audio, and the audio recorded by the recording equipment is obtained in real time in the process of recording the audio. Determining the audio with the preset duration as an original audio file under the condition that the duration of the acquired audio reaches the preset duration; after the original audio file is obtained, deleting noise data in the original audio file, and performing encryption operation on the original audio file to obtain a first audio file; and sending the first audio file to a receiving party.
By the method, the audio can be recorded and transmitted simultaneously in the process of transmitting the audio, the security of audio transmission is ensured, and the effect of improving the audio transmission efficiency is realized.
Optionally, the recording device in this scheme may be a recording device located at a fixed position, or a recording device worn by a worker. The recording equipment can be automatically or manually opened and closed, after the recording equipment is opened, the recording equipment starts recording, and after the recording equipment is closed, the recording equipment finishes recording.
Optionally, in the process of recording the audio in the present scheme, the audio of the predetermined time duration may be determined as an original audio file when the recording device records the predetermined time duration. For example, every 10 minutes of audio recorded by the recording device, the audio recorded within the 10 minutes is saved as an original audio file. In this case, it is possible to record audio and save the original audio file.
Optionally, in the process of recording the audio, if a stop instruction is received under the condition that the audio recorded by the recording device does not reach the predetermined time length, determining the audio not reaching the predetermined time length as the original audio file, wherein the stop instruction is used for closing the recording device. That is, if the recorded audio has not reached the predetermined time period and the recording apparatus is turned off, the audio having not reached the predetermined time period is determined as an original audio file.
Optionally, the case that the audio duration does not reach the predetermined duration may be that the recording apparatus is turned off after the recording apparatus is turned on and the predetermined duration is not reached, or that the recording apparatus is turned off after a plurality of original audio files are recorded (the audio of each predetermined duration is saved as one original audio file) and the audio that is continuously recorded does not reach the predetermined duration, and the audio that is continuously recorded is saved as one original audio file. For example, if the predetermined time is 10 minutes, the recording apparatus is turned off when 10 minutes have not been reached, and the audio of 10 minutes has not been reached is determined as an original audio file. If the recording device records 25 minutes of audio, two 10-minute original audio files and one 5-minute original audio file are obtained.
Alternatively, after the original audio file is acquired, the noise data in the original audio file may be removed. Optionally, the noise data in the present scheme includes a silence segment in the original audio file. That is, there may be a case where no sound is generated for a long time during recording by the recording apparatus. If no one speaks. In this case, a long silence segment is generated. The silence segments need to be deleted.
The specific means can be to obtain a oscillogram of the original audio file; detecting the highest point of the amplitude of each frame of audio file in the oscillogram; determining a predetermined number of audio file frames as the noise data if the highest point of the amplitude of each of the audio file frames in a predetermined number of consecutive audio file frames is less than a predetermined threshold; deleting the noise data; and carrying out encryption operation on the original audio file after the noise data is deleted to obtain the first audio file.
Alternatively, the audio recorded by the recording device may be converted into a numerical value, and the numerical value may be converted into a waveform diagram.
For example, as shown in fig. 2, fig. 2 is a waveform diagram of an alternative original audio file, which contains 5 frames of audio. The highest point of the amplitude of the audio of the first three frames is less than the predetermined threshold 202, and the highest point of the amplitude of the audio exceeds the predetermined threshold 202 at the beginning of the 4 th frame. E.g., the predetermined number is 3, the first three audios are determined to be noise data. If the predetermined number is 4, the first three tones are not really considered as noise data because although the peaks are all less than the predetermined threshold 202, only three frames are consecutive and the predetermined number is not reached.
Alternatively, after the noise data of the original audio file is deleted, the file duration of each of the original audio files from which the noise data is deleted may be different. At this time, the file duration of each original audio file from which the noise data is deleted may be adjusted to the same duration.
For example, the file duration of the original audio file deleted with the noise data is three minutes, which can be adjusted to ten minutes, the adjustment means can be to splice a filler file at the end of the file of the original audio file deleted with the noise data, the data in the filler file is preset data, and the length can be adjusted at will. The encryption efficiency of the filler file during encryption is higher than that of the noise data.
After the populated original audio file is obtained, the populated original audio file is encrypted. In the encryption process, an executable file of the original audio file after filling can be obtained, each bit of data stored in the executable file is 0 or 1, during encryption, each bit of data in the executable file is subjected to negation operation, namely 0 is changed into 1, and 1 is changed into 0, or the negation operation is performed on data of a plurality of target bits in the executable file, and the target is randomly determined or is taken once every a plurality of data bits. And after the first audio file is obtained through encryption, transmitting the first audio file. When the first audio file is transmitted, if the recording equipment is not closed, the recording equipment is always in a state of recording the audio, and the scheme realizes the effect of recording and transmitting the audio.
The following description is made with reference to a specific example.
In the store of getting off on line, the staff has worn intelligent worker's tablet, and intelligent worker's tablet has recording equipment, and after the staff opened recording equipment, recording equipment began to record the audio frequency. And when the audio recorded by the recording equipment reaches 10 minutes, storing the 10-minute audio as an original audio file, and processing the 10-minute original audio file while continuing recording by the recording equipment. First, a waveform diagram of an original audio file is acquired. The audio data of the original audio file may be converted into a numerical value and the numerical value may be converted into a waveform diagram, the abscissa of which is time and the ordinate is sound intensity. If the sound intensity of a plurality of, for example, more than 10 consecutive audio frames is lower than the predetermined threshold, it indicates that there is no human speaking in this time period, and therefore there is no sound, and the data in this time period needs to be deleted as the noise data. After deletion, the remaining audio frames are the audio frames when the staff or the customer speaks. After the above-mentioned deletion action is performed, the time length of the original audio file may be changed, for example, 10 minutes of audio is deleted to 8 minutes. At this time, in order to make the subsequent encryption process not complicated, the original audio file of 8 minutes can be supplemented, and a padding file of 2 minutes is spliced later, the data in the padding file can be preset, and the padding file has high encryption efficiency. After the padding file is spliced to obtain the original audio file of 10 minutes, inverting each bit of the executable file of the original audio file of 10 minutes by bit, for example, replacing 0 with 1, and replacing 1 with 0, and after inverting, obtaining the encrypted first audio file. And transmitting the first audio file to a server for storage.

The recording equipment can be automatically or manually opened and closed, after the recording equipment is opened, the recording equipment starts recording, and after the recording equipment is closed, the recording equipment finishes recording.
Optionally, in the process of recording the audio in the present scheme, the audio of the predetermined time duration may be determined as an original audio file when the recording device records the predetermined time duration. For example, every 10 minutes of audio recorded by the recording device, the audio recorded within the 10 minutes is saved as an original audio file. In this case, it is possible to record audio and save the original audio file.
Optionally, in the process of recording the audio, if a stop instruction is received under the condition that the audio recorded by the recording device does not reach the predetermined time length, determining the audio not reaching the predetermined time length as the original audio file, wherein the stop instruction is used for closing the recording device. That is, if the recorded audio has not reached the predetermined time period and the recording apparatus is turned off, the audio having not reached the predetermined time period is determined as an original audio file.
Optionally, the case that the audio duration does not reach the predetermined duration may be that the recording apparatus is turned off after the recording apparatus is turned on and the predetermined duration is not reached, or that the recording apparatus is turned off after a plurality of original audio files are recorded (the audio of each predetermined duration is saved as one original audio file) and the audio that is continuously recorded does not reach the predetermined duration, and the audio that is continuously recorded is saved as one original audio file. For example, if the predetermined time is 10 minutes, the recording apparatus is turned off when 10 minutes have not been reached, and the audio of 10 minutes has not been reached is determined as an original audio file. If the recording device records 25 minutes of audio, two 10-minute original audio files and one 5-minute original audio file are obtained.
