Referring to fig. 2, a flow 200 of one embodiment of an audio processing method is shown. The embodiment is mainly exemplified by applying the method to an electronic device with certain computing capability, and the electronic device may be the terminal device shown in fig. 1. The audio processing method comprises the following steps:
In the present embodiment, the execution subject of the audio processing method (e.g., the terminal device shown in fig. 1) may acquire the sound recording data.
In this embodiment, the recorded sound data may be audio data collected by the execution subject or other electronic device. The executing body can directly collect or receive the recording data from other electronic equipment to obtain the recording data.
In this embodiment, the execution main body may process the recording data to obtain the data to be played.
In this embodiment, the data to be played back may be audio data in a time domain.
In the present embodiment, the recording data may be processed in various ways.
As an example, the processing means may include, but is not limited to: performing time-frequency transformation on the recording data in the time domain form to obtain frequency spectrum data; processing the spectral data with at least one of the following speech signals: noise removal, automatic gain control and echo cancellation; and transforming the frequency spectrum data after the voice signal processing to a time domain to be used as data to be played.
In this embodiment, the execution main body may determine whether to adjust the data to be played according to the information of the presentation range of the audio data by the playback device.
In this embodiment, the playback device may be an electronic device that plays back data to be played back later.
As an example, the execution main body is a terminal device a, and the playback device may be a terminal device b. In an application scenario of a call between the terminal device a and the terminal device b, the playback device may be the terminal device b that is to play the data to be played later.
It will be appreciated that the presentation of audio data by the playback apparatus described above may be within certain limits. This range can be indicated using the above-described representation range information. As an example, the above-described expression range is range information indicated by a length indicating 8 bits, 16 bits, or 32 bits.
In this embodiment, the execution main body may first obtain the representation range information of the audio data of the playback data, and then determine whether to adjust the playback data in various ways.
Alternatively, the reference threshold value may be determined based on the full-scale value indicated by the above-described indication range information. For example, the full-width value indicated by the indication range information may be used as the reference threshold, and for example, 90% of the full-width value indicated by the indication range information may be used as the reference threshold.
As an example, step 203 may be implemented by: and if the audio data points which overflow (namely exceed) the range indicated by the representation range information exist in the data to be played, determining to adjust the data to be played.
As an example, step 203 may be implemented by: and if the audio data points exceeding the reference threshold (for example, 90% of the full amplitude value) exist in the data to be played, determining to adjust the data to be played. It should be noted that, by setting a reference threshold smaller than the full amplitude, it is possible to perform an advance smoothing adjustment on the audio points exceeding the threshold, so as to avoid clipping after reaching the full amplitude, thereby achieving a consistent loudness hearing.
And step 204, adjusting the data to be played in response to the determination of the adjustment of the data to be played.
In this embodiment, the execution main body may adjust the data to be played in response to determining to adjust the data to be played.
In this embodiment, the step 204 can be implemented in various ways.
As an example, the execution subject described above may multiply the data to be played back by the attenuation coefficient as a whole in response to determining that the data to be played back is adjusted.
Before playing, the data to be played is determined to be adjusted or not according to the information of the representation range of the audio data by the playing equipment, and if the adjustment is determined to be needed, the data to be played is adjusted. Therefore, if the data to be played is in an expected state (for example, the data to be played overflows the representation range), the data to be played can be adjusted in time so as to adjust the data to be played to the expected state.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the audio processing method according to the embodiment shown in fig. 2. In the application scenario of fig. 3:
first, the terminal 301 may collect voice uttered by the user to acquire recorded data.
Then, the terminal 301 may process the recording data to obtain data to be played.
Then, the terminal 301 may determine whether to adjust the data to be played back according to the representation range information of the playback device on the audio data. In the application scenario, the playback device may be the terminal 301.
Then, the terminal 301 may adjust the data to be played in response to the determination, and adjust the data to be played to obtain playback data.
Finally, the terminal 301 can read the playback data for playback.
With continued reference to fig. 4, fig. 4 is a schematic diagram of another application scenario of the audio processing method according to the embodiment shown in fig. 2. In the application scenario of fig. 4:
first, the terminal 401 may collect voice uttered by the user to acquire recorded data.
Then, the terminal 401 can transmit the sound recording data to the server 402.
Then, the server 402 may process the recording data to obtain data to be played.
Then, the server 402 can determine whether to adjust the data to be played according to the representation range information of the audio data by the playback device. In the context of this application, the playback device may be a terminal 403.
Then, the server 402 may adjust the data to be played in response to the determination, and adjust the data to be played to obtain playback data.
Finally, the server 402 can send the playback data to the terminal 403, and the terminal 403 plays the playback data.
The method provided by the above embodiment of the present disclosure determines whether to adjust the data to be played according to the representation range of the playback device on the audio data before playback, and if it is determined that adjustment is needed, adjusts the data to be played, and the technical effects at least may include: a new audio processing approach is provided.
In some embodiments, the above-mentioned indication range information includes an indication threshold.
In some embodiments, step 204 may include steps 2041 and 2042 shown in fig. 5, where:
Here, the execution body may compare data in the data to be played with the representation threshold, thereby finding out data greater than the representation threshold. And determining the data which is larger than the representation threshold value in the data to be played as the over-range data.
And 2042, adjusting the data to be played based on the over-range data.
Here, the execution body may adjust data to be played back in various ways based on the out-of-range data.
In some embodiments, step 2042 may include: and adjusting the numerical value of the out-of-range data to the representation threshold. Here, the over-range data may be adjusted to represent a threshold value, whereby pop sounds may be avoided when playing back sounds.
In some embodiments, step 2042 may include: and multiplying the whole data to be played by an attenuation coefficient. Here, the attenuation coefficient may be determined from the over-range data. It should be noted that, the above-mentioned data to be played are multiplied by the attenuation coefficient, which not only ensures that there is no over-range data in the data to be played, and avoids the pop sound of playing, but also can quickly realize the adjustment, and improve the efficiency of adjustment.
In some embodiments, step 2042 may include: determining a data subsection to be played where the over-range data is located according to the position of the over-range data in the data to be played and a preset interval threshold; and adjusting the sub-segments of the data to be played.
Here, two data points that are apart from the position by a preset interval threshold value in the data to be played may be found, and then, a portion between the two found data points may be used as a data sub-segment to be played. The sub-segments of the data to be played can be adjusted, thereby avoiding adjusting the data to be played in a large range, improving the accuracy and pertinence of adjustment and avoiding popping sound during playing.
With further reference to fig. 6, a flow 600 of yet another embodiment of an audio processing method is shown. The flow 600 of the audio processing method comprises the following steps:
In the present embodiment, the execution subject of the audio processing method (e.g., the terminal device shown in fig. 1) may acquire the sound recording data.
In this embodiment, please refer to the description of step 201, step 202, and step 203 in the embodiment shown in fig. 2 for details and technical effects of step 601, step 602, and step 603, which are not described herein again.
In this embodiment, please refer to the description of step 2041 for details and technical effects of step 604, which are not described herein again.
Predefined characteristic information of the out-of-range data is determined, step 605.
In this embodiment, the execution subject determines predefined characteristic information of the out-of-range data.
In this embodiment, the characteristic information may be used to indicate a characteristic of the out-of-range data.
In some embodiments, the feature information may include distribution information of the over-range data in the data to be played.
In some embodiments, the characteristic information may include an extent of the exceeding of the out-of-range data with respect to the representation threshold. Here, the exceeding degree information may be represented in various forms, and for example, a ratio of a numerical value of the out-of-range data to the above-described representation threshold value may be used as the exceeding length information. The ratio can also be compared with a preset ratio threshold value to obtain the exceeding degree information such as serious exceeding, ordinary exceeding and the like.
And step 606, adjusting the data to be played according to the characteristic information.
In this embodiment, the execution body adjusts the data to be played back according to the feature information.
In this embodiment, the feature information may have one or more items, and the data to be played may be adjusted by using the synthesis according to the one or more items of feature information.
In some embodiments, the step 606 may include: determining whether the adjustment mode of the data to be played is needed according to the distribution information, wherein the adjustment mode comprises all adjustment and partial adjustment; and adjusting the data to be played according to the determined adjustment mode. The overall adjustment may be an adjustment of the data to be played as a whole, for example an overall multiplication by an attenuation factor. The partial adjustment may be an adjustment of a portion of the data to be played, for example, a portion of the data to be played multiplied by an attenuation factor.
Here, the distribution information may include: the proportion of the over-range data in the data to be played, the number of continuous over-range data blocks and the like.
It should be noted that the distribution information may indicate the dense length of the over-range data in the data to be played. If the over-range data is dense in the data to be played, all adjustment modes can be used for adjustment. If the over-range data is dispersed in the data to be played, the adjustment can be performed by using a partial adjustment mode. Therefore, the adjustment mode can be flexibly selected to process the data to be played, and both the adjustment efficiency and the adjustment accuracy are considered.
In some embodiments, the step 606 may include: determining an attenuation coefficient according to the exceeding degree information; and adjusting the data to be played according to the determined attenuation coefficient.
The attenuation coefficient is determined according to the exceeding degree information, and the attenuation coefficient suitable for the data to be played at this time can be determined, so that the adjustment accuracy is realized, the data to be played is not adjusted to exceed the range, and the data to be played is not attenuated too much.
As can be seen from fig. 6, compared with the embodiment corresponding to fig. 2, the flow 600 of the audio processing method in this embodiment highlights the steps of determining the feature information of the out-of-range data and adjusting the data to be played according to the feature information.
