Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

In recent years, with the continuous development of smart terminal technology and the development of Internet technology, more and more users watch short videos through smart devices such as mobile phones. The content of short videos covers all aspects of life and greatly enriches people's spare time. and field of view. However, the volume of the sound source of the short video is usually uneven, causing the user to repeatedly adjust the volume while viewing the short video, resulting in a poor user experience.

As a way to adjust the volume, the smart device can be configured with a volume balance function, so that the audio playback volume can be automatically balanced. Among them, the principle of volume balance is to scan the volume information of all audios to calculate the average volume. For loud audio, the sound is reduced to approach the average value, and for the low-sound audio, the sound is increased to approach the average value, so that achieve volume balance. However, the inventor has found through long-term research that the related volume balance function has a limited scope of use (for example, it can only be applied to local audio sources, and needs to be connected to specific software to use), and it is not smart enough.

In order to optimize the above problems, the embodiment of the present application proposes that the playback volume of the audio to be processed can be adaptively adjusted according to the amplitude gear to which the signal amplitude of the audio to be processed belongs, so that the playback volume of the audio to be processed is equal to the target volume Approximate to improve the intelligence of the volume control volume control method and device, electronic equipment and storage media.

Various embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Please refer to FIG. 1 , which shows a method flowchart of a volume control method provided by an embodiment of the present application. The volume control method provided by this embodiment can be applied to electronic devices, and the method includes:

Step S110: Obtain the amplitude level to which the signal amplitude of the audio to be processed belongs.

The audio to be processed in the embodiment of the present application is the audio to be played online in real time (for example, it can be the audio to be played after buffering), and the audio to be processed in this way can come from video, short video or audio on the network . Optionally, in other implementation manners, the audio to be processed may be audio to be played, and the audio to be processed in this manner may originate locally. In this embodiment of the present application, the content form of the audio to be processed may not be limited. For example, the audio to be processed may be music, movie dubbing, recitation program audio, or radio program audio.

Among them, the amplitude of the audio to be processed represents the maximum absolute value of the alternating current instantaneously within one cycle, and the maximum absolute value can be understood as the distance from the peak to the trough in the audio signal sine wave diagram of the audio to be processed, and can also be understood as expressing A value for the loudness of the signal. A piece of audio to be processed can have multiple amplitudes. For a piece of audio to be processed, the signal amplitude of the audio to be processed in the embodiment of the present application represents the average value of the signal amplitude of the audio to be processed. As a way, it can be detected by detecting Multiple amplitudes of the audio are processed to calculate the average signal amplitude of the audio to be processed, and different audios to be processed correspond to their own average signal amplitudes.

The magnitude of the signal amplitude of the audio to be processed will affect the degree of gain to the sound source in the way of balancing the volume. For example, if the signal amplitude of the audio to be processed is higher than the average value of the signal amplitude, the audio source corresponding to the audio needs to be negatively adjusted. Gain processing; if the signal amplitude of the audio to be processed is lower than the average value of the signal amplitude, it is necessary to perform positive gain processing on the audio source corresponding to the audio. In this way, when balancing the volume of each audio segment, it is necessary to compare the signal amplitude with the signal The magnitude of the average value of the amplitude, and corresponding gain processing is performed according to the comparison result, which increases the complexity of the volume balance processing and reduces the intelligence of the volume adjustment process.

In the embodiment of the present application, the audio signal amplitude is divided into gears (abbreviated as binning), and at least two amplitude gears are obtained, and each amplitude gear can include the same number of signal amplitudes, and the specific value of the number It may not be limited, for example, each amplitude level may include 10 signal amplitudes or 100 signal amplitudes. Among them, the amplitude gears corresponding to different audio signal amplitudes can be different, or the amplitude gears corresponding to audio with different signal amplitudes can be the same. For example, suppose the amplitude gears obtained after binning include -20db～ -10db and -10db～0db, then the signal amplitude -15db belongs to the amplitude gear -20db～-10db, and the signal amplitude -5db belongs to the amplitude gear -10db～-0db; the signal amplitude -8db and -6db All belong to the range of amplitude -10db～-0db.

In this way, for the average signal amplitude value of the audio to be processed obtained in this application, the amplitude gear to which the average signal amplitude value belongs can be determined, and then the gain degree of the audio to be processed can be determined according to the amplitude gear. Realizing the volume balance avoids realizing the volume balance by comparing the magnitude of each signal amplitude of the audio to be processed with the average value of the signal amplitude, thereby reducing the complexity of the volume balance processing.

Step S120: Obtain the volume adjustment amount corresponding to the amplitude level.

In the embodiment of the present application, different amplitude gears correspond to different volume adjustment amounts, that is, signal amplitude mean values of different amplitude gears correspond to different volume adjustment amounts. By acquiring the volume adjustment amount corresponding to the amplitude gear, the playback volume of the audio to be processed can be adjusted more intelligently according to the volume adjustment amount corresponding to the amplitude gear where the average signal amplitude of the audio to be processed is located.

Step S130: Adjust the playback volume of the audio to be processed by the volume adjustment amount, so that the playback volume of the audio to be processed is close to a target volume, and the target volume is a value determined according to user habits.

Among them, the target volume is a value determined according to the user's habits. The target volume can be understood as the user's preferred volume under the current type of audio to be processed. The type of audio to be processed is different, and the corresponding target volume can be different, or the content of the audio to be processed. The corresponding target volumes may be different. By adjusting the playback volume of the audio to be processed with the volume adjustment amount corresponding to the amplitude level to which the signal amplitude of the audio to be processed belongs, the adjusted playback volume of the audio to be processed can be made close to the target volume.

It should be noted that the average signal amplitude of the audio to be processed in the embodiment of the present application corresponds to an amplitude level, and in order to meet the user's preferred loudness when the audio to be processed starts to play, you can start the audio to be processed During playback, the playback volume of the audio to be processed is adjusted with the obtained volume adjustment amount, so that by adjusting the playback volume once, the playback volume of the audio to be processed during the entire playback process can meet the user's preferred loudness. Wherein, adjusting the playback volume of the audio to be processed refers to adjusting the volume of the electronic device to play the audio to be processed.

Optionally, after the playback volume of the audio to be processed is adjusted through the volume control method in this embodiment, if the user adjusts the playback volume of the audio to be processed by himself, the electronic device can use the volume adjusted by the user to play the audio to be processed. to resume playback.

The volume adjustment method in this embodiment can be executed when the audio to be played is switched from other audio to audio to be processed, or can be executed when the audio to be played is switched from audio to be processed to other audio. The volume adjustment amount corresponding to the bit adjusts the playback volume of the audio to be processed, so that the electronic device can automatically adjust the playback volume of the audio to be processed in a targeted manner, thereby improving the intelligence of the volume control.

A volume control method provided by the present application obtains the amplitude gear to which the signal amplitude of the audio to be processed belongs, and then obtains the volume adjustment amount corresponding to the amplitude gear, and different amplitude gears correspond to different volume adjustment amounts, and then adjust the playback volume of the audio to be processed by the volume adjustment amount, so that the playback volume of the audio to be processed is close to the target volume. This method realizes that the playback volume of the audio to be processed can be adaptively adjusted according to the amplitude gear to which the signal amplitude of the audio to be processed belongs, so that the playback volume of the audio to be processed is close to the target volume, and the efficiency of volume control is improved. intelligence.

Please refer to FIG. 2 , which shows a method flowchart of a volume control method provided in another embodiment of the present application. The volume control method provided in this embodiment can be applied to electronic devices, and the method includes:

Step S210: Obtain the average value of the amplitude corresponding to each of the plurality of audio samples.

Wherein, the multiple sample audios may be audios of different content types, may be audios of the same content type, or may be a combination of audios of the same content type and audios of different content types. The source of sample audio may not be limited, for example, it may come from video, short video or audio played online in real time.

As a way, the signal amplitude of each audio in multiple sample audios can be obtained, wherein a sample audio includes multiple frames of audio, each frame of audio corresponds to a signal amplitude, and then calculated according to the respective signal amplitudes The average value of the audio amplitude for each sample.

Step S220: Obtain a designated volume level corresponding to each audio in the plurality of audio samples.

Wherein, the volume level represents the playback volume, and the specified volume level represents the user's usual (or preferred) playback volume, and the specified volume levels corresponding to different sample audios may be different.

In one implementation, the volume level of each of the multiple sample audios at the end of playback can be obtained, where the end of playback can be understood as the moment when the last frame of audio is played, and the volume level at the end of playback can be understood as To play the volume level of the last frame of audio, the volume level at the end of playback can be defaulted to the volume level preferred by the user, then the volume level of the audio at the end of playback can be used as the specified volume level corresponding to the audio.

In another implementation, the volume level of the audio at the end of playback can be detected first, if the volume level of the audio at the end of playback is lower than the preset volume level (at this time, the volume level can be 0, that is, the mute state , for example, if the user turns down the volume when listening to a song and gets sleepy, the music will play at the lowered volume until it finishes playing, or if the user turns the volume of the phone to silent mode while in a meeting, then The music will be played in silent mode until the end of the playback, at this time even if the music is playing, no sound can be heard), the preset volume level can be the critical volume level that allows the user to hear the sound, in this way, in order to ensure that the The user plays the sample audio at the customary playback volume, and can obtain the specified volume level corresponding to each of the multiple sample audios in a full sampling manner. Specifically, the volume level corresponding to the sample audio in any playback period may be acquired, and then the average of all acquired volume levels may be obtained to obtain the specified volume level.

Optionally, if the user suddenly lowers the playback volume during music playback, you can obtain the moment when the audio playback volume was lowered for the first time and the volume corresponding to each previous moment, and then follow the full sampling The specified volume level corresponding to the audio is acquired in a manner, and the specific acquisition principle is similar to the above-mentioned implementation manner, and will not be repeated here.

Step S230: Obtain a target volume corresponding to the audio to be processed based on the amplitude mean value and the specified volume level.

As a manner, the user preference volume may be constructed based on the amplitude mean value and the specified volume level as the target volume corresponding to the audio to be processed. In a specific application scenario, assuming that the audio to be processed is audio A, the volume of audio A played by the user at different time periods can be recorded. For example, the volume of audio A played by the user in the morning can be recorded as a1, and the volume of audio A played by the user at noon can be recorded. The volume of audio A is a2. Record the volume of audio A played by the user at night is a3, and the average amplitude of audio A is B. Then the user portrait can be constructed based on a1, a2, a3, and B. Specifically, a1, a2, a3, and B are input to the machine learning model to learn the user's preferred volume. In this way, the user's preferred volume can be used as the target volume corresponding to the audio to be processed.

Step S240: Obtain the amplitude level to which the signal amplitude of the audio to be processed belongs.

Step S250: Obtain the volume adjustment amount corresponding to the amplitude gear.

As an implementation, in order to facilitate the playback volume of the audio to be processed in the loudness range preferred by the user, when obtaining the volume adjustment corresponding to the amplitude gear, the amplitude gear can be determined based on the target volume The corresponding volume adjustment amount, specifically, the volume adjustment amount corresponding to the signal amplitude mean value of the amplitude gear can be determined based on the target volume (in this way, the volume adjustment amount corresponding to the signal amplitude mean value of the amplitude gear can be Volume adjustment amount, as the volume adjustment amount corresponding to the amplitude level), so that the adjusted playback volume of the audio to be processed can be close to the target volume.

For example, in a specific application scenario, assuming that the target volume is -40db, the signal amplitude of the audio to be processed is divided into 6 gears, which are: -60db～-50db, -50db～-40db, -40db～ -30db, -30db～-20db, -20db～-10db, -10db～0db, the average signal amplitudes of the signal amplitudes of the 6 gears are -55db, -45db, -35db, -25db, -15db , -5db, then, combined with the target volume, it can be determined that the volume adjustments corresponding to the mean values of the six signal amplitudes are +15db, +5db, -5db, -15db, -25db, -35db, where the signal amplitude The average value of -55db can be understood as the current reference playback volume of the audio to be processed is -55db (it should be noted that the reference playback volume here can be understood as an approximate playback volume, assuming that the signal amplitude of the audio to be processed is -52db, because- If 52db falls within the amplitude range -60db~-50db, then the volume adjustment corresponding to the average signal amplitude of the amplitude range -60db~-50db -55db can also be used as the volume adjustment corresponding to the signal amplitude -52db Volume), in order to make the playback volume of the audio to be processed close to the target volume, the playback volume of the audio to be processed can be controlled to be adjusted by +15db, so that the playback volume of the audio to be processed after adjustment is -55db+15db=-40db, The numerical values cited above are only used as examples for illustration, and do not constitute a limitation to this solution, and other numerical values may be used in actual implementation. Similarly, when the signal amplitude of the audio to be processed falls in other gears, by adjusting the playback volume of the audio to be processed with the volume adjustment corresponding to other amplitude gears, the playback of the adjusted audio to be processed can also be adjusted. The volume is the same as or close to the target volume, which will not be repeated here. It should be noted that the value of the target volume in this embodiment can be changed, and as the target volume changes, the electronic device in this embodiment can determine the volume adjustment corresponding to the amplitude level based on the target volume in real time.

As another implementation manner, the volume adjustment amount corresponding to the amplitude level can be obtained from a preset table, wherein the preset table is determined according to the target volume. Specifically, the corresponding volume adjustment amount can be configured for the signal amplitude mean value of each amplitude gear, and the corresponding relationship between the amplitude gear and the volume adjustment amount can be stored in the form of a table. In this way, when When a certain signal amplitude falls in an amplitude range, the volume adjustment corresponding to the average value of the signal amplitude of the amplitude range can be used as the volume adjustment corresponding to the signal amplitude, that is, it can be selected from the preset table Find the volume adjustment amount corresponding to the amplitude gear to which the signal amplitude belongs. It should be noted that, compared with the previous embodiment, when obtaining the volume adjustment amount in this embodiment, the association relationship between the target volume, the amplitude level and the volume adjustment amount can be established, and the related amplitude determined based on the target volume can be calculated in real time. The volume adjustment amount corresponding to the value gear is stored in the form of a preset table. In this way, the volume adjustment amount corresponding to the amplitude gear determined based on the target volume of various values can be stored in the preset table, and then When obtaining the volume adjustment amount corresponding to the amplitude gear, the volume adjustment amount corresponding to the amplitude gear can be obtained directly from the preset table by looking up the table, that is, the volume adjustment amount acquisition process in this way It is static, and does not need to calculate the volume adjustment corresponding to the amplitude gear based on the target volume each time, thereby saving the power consumption of the electronic device.

Step S260: Adjust the playback volume of the audio to be processed by the volume adjustment amount, so that the playback volume of the audio to be processed is close to a target volume, and the target volume is a value determined according to user habits.

A volume control method provided by the present application is obtained by obtaining the respective amplitude mean values corresponding to a plurality of sample audios; obtaining the specified volume level corresponding to each audio in the plurality of sample audios; based on the amplitude mean value and the Specify the volume level to obtain the target volume corresponding to the audio to be processed; obtain the amplitude gear to which the signal amplitude of the audio to be processed belongs; obtain the volume adjustment corresponding to the amplitude gear; adjust the volume with the volume adjustment The playback volume of the audio to be processed, so that the playback volume of the audio to be processed is close to the target volume. This method realizes that the playback volume of the audio to be processed can be adaptively adjusted according to the amplitude gear to which the signal amplitude of the audio to be processed belongs, so that the playback volume of the audio to be processed is close to the target volume, and the efficiency of volume control is improved. intelligence.

Step S310: Obtain scene information to which the audio to be processed belongs.

There may be multiple content types of the audio to be processed, and different content types of the audio to be processed belong to different scene information, and the scene information may be understood as a usage scene of the audio to be processed. For example, if the audio to be processed is rock music, the scene information of the audio to be processed can be a music festival scene; if the audio to be processed is light music, the scene information to which the audio to be processed can be a learning scene; music, then the scene information to which the audio to be processed belongs may be a sleep scene. As one manner, the scene information corresponding to the audio to be processed of different content types may be pre-configured, then the scene information to which the audio to be processed belongs may be acquired according to the content type of the audio to be processed.

As another manner, the scene information to which the audio to be processed belongs may be determined according to the location of the electronic device, wherein the electronic device may determine its location in combination with the location information and the camera. For example, when it is detected that the electronic device is in public places such as hospitals and subways (in public places, it is recommended not to play the volume of the electronic device outside, so as not to disturb other users in private), it can be determined that the scene information of the audio to be processed belongs to the earphone wearing and playing scene. If it is detected that the electronic device is in a place such as a museum, then it may be determined that the scene information to which the audio to be processed belongs is a silent scene.

Step S320: Use the volume corresponding to the scene information as the target volume corresponding to the audio to be processed.

Different scene information may be correspondingly configured with different volumes. After determining the scene information to which the audio to be processed belongs, the volume corresponding to the scene information may be used as the target volume corresponding to the audio to be processed.

Step S330: Obtain the amplitude level to which the signal amplitude of the audio to be processed belongs.

Step S340: Determine a volume adjustment amount corresponding to the amplitude level based on the target volume.
