All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise 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 embodiment 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 starting a recording device, acquiring the audio recorded by the recording device in real time in the process of recording the audio by the recording device;
s104, determining the audio with the preset time length as an original audio file under the condition that the acquired time length of the audio reaches the preset time length;
S106, deleting noise data in the original audio file after the original audio file is acquired, and executing encryption operation on the original audio file to obtain a first audio file;
s108, the first audio file is sent to a receiver.
Optionally, the audio transmission method can be applied to a terminal capable of calculating data, such as a mobile phone, a tablet computer, a notebook computer, a PC (personal computer) and the like, or an intelligent device, such as an intelligent tablet, an intelligent recording device and the like. The terminal or smart device may interact with the server over a network, which may include, but is not limited to, a wireless network or a wired network. Wherein the wireless network comprises: WIFI and other networks that enable wireless communications. The wired network may include, but is not limited to: wide area network, metropolitan area network, local area network. The server may include, but is not limited to, any hardware device that can perform the calculations.
Alternatively, the above-described audio transmission method may be applied to the field of audio encryption transmission, but is not limited thereto. Taking audio encryption transmission as an example, after the recording device is started, the recording device starts to record audio, and the audio recorded by the recording device is obtained in real time in the process of recording the audio. Under the condition that the acquired time length of the audio reaches a preset time length, determining the audio with the preset time length as an original audio file; after the original audio file is obtained, deleting noise data in the original audio file, and executing encryption operation on the original audio file to obtain a first audio file; and sending the first audio file to a receiver.
By the method, the audio can be recorded and transmitted simultaneously in the audio transmission process, the audio transmission safety is ensured, and the audio transmission efficiency is improved.
Optionally, the recording device in the scheme can be a recording device located at a fixed position or a recording device worn by a worker. The recording device can be automatically or manually opened and closed, after the recording device is opened, the recording device starts recording, and after the recording device is closed, the recording device ends recording.
Optionally, in the audio recording process in this embodiment, the audio of the predetermined duration may be determined as an original audio file in each case that the recording device records the predetermined 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, recording audio while saving the original audio file can be realized.
Optionally, in the process of recording audio, if a stop instruction is received under the condition that the audio recorded by the recording device does not reach the preset time length, determining the audio which does not reach the preset 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 length of time, the recording apparatus is turned off, and the audio that has not reached the predetermined length of time is determined as an original audio file.
Alternatively, the case where the audio duration does not reach the predetermined duration may be that the recording device is turned on, the recording device is turned off when the predetermined duration has not been reached, or after a plurality of original audio files are recorded (each of the audio files of the predetermined duration is stored as one of the original audio files), and when the audio to be continuously recorded does not reach the predetermined duration, the recording device is turned off, and the audio to be continuously recorded is stored as one of the original audio files. For example, if the predetermined time period is 10 minutes, the recording device is turned off when the predetermined time period is not 10 minutes, and the audio which is not 10 minutes is determined as an original audio file. If the recording device recorded 25 minutes of audio, two 10 minutes of original audio files and one 5 minutes of original audio file were obtained.
Alternatively, after the original audio file is acquired, noise data in the original audio file may be removed. Optionally, the noise data in the present scheme includes silence segments in the original audio file. That is, there may be a case where no sound is generated for a long time during the recording by the recording apparatus. Such as no one speaking. At this time, a longer mute segment is generated. The silence segments need to be deleted.
The specific means may be to obtain a waveform diagram 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 in the case where the highest point of the amplitude of each of the audio file frames is less than a predetermined threshold value in the consecutive predetermined number of audio file frames; deleting the noise data; and executing encryption operation on the original audio file after deleting the noise data 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 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, frame 4 begins and the highest point of the amplitude of the audio exceeds the predetermined threshold 202. For example, a predetermined number of 3, the first three tones are determined to be truly noise data. If the predetermined number is 4, the first three tones will not be considered as noise data because only three frames are connected and the predetermined number is not reached, although the amplitude peak is less than the predetermined threshold 202.
Alternatively, after deleting noise data of the original audio files, file durations of the original audio files each of which has deleted noise data may be different. At this time, the file duration of each original audio file from which noise data is deleted may be adjusted to the same duration.
For example, the file duration of the original audio file with the noise data deleted is three minutes, the original audio file can be adjusted to ten minutes, the adjustment means can be to splice a filling file at the end of the original audio file with the noise data deleted, the data in the filling file is preset data, and the length can be adjusted at will. The encryption efficiency of the filler file in the encryption process is higher than that of the noise data.
After obtaining the filled original audio file, encrypting the filled original audio file. In the encryption process, an executable file of the filled original audio file can be obtained, each bit of data stored in the executable file is 0 or 1, and when in encryption, each bit of data in the executable file is subjected to inversion operation, namely 0 is changed to 1,1 is changed to 0, or inversion operation is performed on data of a plurality of target bits in the executable file, and the aim is to randomly determine or take every other 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 audio, and the effect of recording the audio and transmitting the audio is realized.
The following is described in connection with a specific example.
In the online store, the staff wears intelligent work card, and intelligent work card has recording equipment, and after the staff opened recording equipment, recording equipment began recording audio frequency. When the audio recorded by the recording device reaches 10 minutes, the audio of 10 minutes is stored as an original audio file, and at the moment, the recording device continues recording and processes the original audio file of 10 minutes. 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 converted into a waveform diagram, the abscissa of which is time and the ordinate of which is sound intensity. If the sound intensity of a plurality of consecutive audio frames, such as 10 or more consecutive audio frames, is below a predetermined threshold, this time period is indicated, and there is no possibility that a person is speaking, and therefore, the data of this time period needs to be deleted as noise data. After deletion, the remaining audio frames are those when the worker or customer speaks. After the deletion action described above is performed, the duration 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 operation of the subsequent encryption process not complex, the original audio file of 8 minutes can be supplemented, and the filling file of 2 minutes is spliced later, the data in the filling file can be preset, and the encryption efficiency of the filling file is high. After the filling file is spliced to obtain an original audio file for 10 minutes, each bit of the executable file of the original audio file for 10 minutes is inverted by bit, for example, 0 is replaced by 1,1 is replaced by 0, and after the inversion, the encrypted first audio file is obtained. The first audio file is transmitted to the server for saving.
