Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In recent years, with the continuous development of intelligent terminal technology and the development of internet technology, more and more users watch short videos through intelligent devices such as mobile phones, the content of the short videos covers the aspects of life, and the amateur life and the visual field of people are greatly enriched. However, the sound source volume of the short video is usually uneven, so that the user needs to repeatedly adjust the volume in the process of refreshing the short video, and the user experience is poor.
As a mode for adjusting the volume, a volume balance function can be configured for the intelligent device, so that the playing volume of the audio can be automatically balanced. The principle of the volume balance is that the volume information of all audio frequencies is scanned once, the average volume is calculated, the average value is close to the average value through a sound reduction shell for the audio frequency with large sound, and the average value is close to the average value through a sound addition shell for the audio frequency with small sound, and therefore the effect of volume balance is achieved. However, the inventor has found through long-term research that the related volume balance function has a limited range of applications (for example, only can be applied to a local sound source, and a specific software needs to be connected for use), and is not intelligent enough.
In order to optimize the above problem, embodiments of the present application provide a volume control method and apparatus, an electronic device, and a storage medium, which can adaptively adjust the playing volume of a to-be-processed audio according to an amplitude gear to which a signal amplitude of the to-be-processed audio belongs, so that the playing volume of the to-be-processed audio is close to a target volume, thereby improving the intelligence of volume control.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of a method for controlling a volume according to an embodiment of the present application is shown, where the method for controlling a volume according to the embodiment is applicable to an electronic device, and the method includes:
step S110: and acquiring an amplitude gear to which the signal amplitude of the audio to be processed belongs.
The audio to be processed in this embodiment of the application is an audio to be played online in real time (for example, the audio to be played after buffering is completed), and the audio to be processed in this manner may be derived from a video, a short video, or an audio on a network. Optionally, in other embodiments, the audio to be processed may be audio to be played, and the audio to be processed in this manner may originate from the local. In the embodiment of the present application, the content form of the to-be-processed audio may not be limited, for example, the to-be-processed audio may be music, movie dubbing, recited program audio, or station program audio.
The amplitude of the audio to be processed represents the maximum absolute value of the instantaneous appearance of the alternating current in one period, and the maximum absolute value can be understood as the distance from a peak to a trough in an audio signal sine wave diagram of the audio to be processed and can also be understood as a value representing the signal sound size. For a section of audio to be processed, the signal amplitude of the audio to be processed in the embodiment of the present application represents the signal amplitude mean value of the audio to be processed, and as a manner, the signal amplitude mean value of the audio to be processed may be calculated by detecting the plurality of amplitudes of the audio to be processed, and different audio to be processed each corresponds to a respective signal amplitude mean value.
The magnitude of the signal amplitude of the audio to be processed may affect the gain degree of the sound source in the manner of the relevant balanced volume, for example, if the signal amplitude of the audio to be processed is higher than the signal amplitude mean value, negative gain processing needs to be performed on the sound source corresponding to the audio; if the signal amplitude of the audio to be processed is lower than the average value of the signal amplitudes, positive gain processing needs to be performed on the sound source corresponding to the audio, and thus, when the volume of each section of audio is balanced, the signal amplitudes and the average value of the signal amplitudes need to be compared, and corresponding gain processing is performed according to the comparison result, so that the complexity of volume balance processing is increased, and the intelligence of the volume adjustment process is reduced.
In the embodiment of the present application, the signal amplitudes of the audio are divided into steps (referred to as "step"), so as to obtain at least two amplitude steps, each amplitude step may include the same number of signal amplitudes, and specific values of the number may not be limited, for example, each amplitude step may include 10 signal amplitudes or 100 signal amplitudes. For example, if the amplitude levels obtained after the stepping include-20 db to-10 db and-10 db to 0db, the signal amplitude of-15 db belongs to the amplitude levels of-20 db to-10 db, and the signal amplitude of-5 db belongs to the amplitude levels of-10 db to-0 db; the signal amplitudes of-8 db and-6 db belong to the amplitude range of-10 db to-0 db.
In this way, for the signal amplitude mean value of the audio to be processed obtained in the present application, the amplitude gear to which the signal amplitude mean value belongs can be determined, and then the gain degree of the audio to be processed is determined according to the amplitude gear to realize the volume balance, thereby avoiding realizing the volume balance by comparing the magnitude of each signal amplitude of the audio to be processed with the magnitude of the signal amplitude mean value, and further reducing the complexity of the volume balance processing.
Step S120: and acquiring the volume adjustment amount corresponding to the amplitude gear.
In the embodiment of the application, different amplitude gears correspond to different volume adjustment amounts, that is, the signal amplitude mean values of the different amplitude gears correspond to different volume adjustment amounts. By obtaining the volume adjustment amount corresponding to the amplitude gear, the playing 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 signal amplitude mean value of the audio to be processed is located.
Step S130: and adjusting the playing volume of the audio to be processed by using the volume adjustment amount so as to enable the playing volume of the audio to be processed to be close to a target volume, wherein the target volume is a value determined according to the habit of a user.
The target volume is a value determined according to user habits, the target volume can be understood as user preference volume under the current type of audio to be processed, the types of the audio to be processed are different, the corresponding target volumes can be different, or the content of the audio to be processed is different, and the corresponding target volumes can be different. The playing volume of the audio to be processed is adjusted by the volume adjustment amount corresponding to the amplitude gear to which the signal amplitude of the audio to be processed belongs, so that the adjusted playing volume of the audio to be processed is close to the target volume.
It should be noted that, the signal amplitude mean value of the to-be-processed audio in the embodiment of the present application corresponds to an amplitude gear, and in order to facilitate that the to-be-processed audio can meet the preference loudness of the user when the to-be-processed audio starts to be played, the play volume of the to-be-processed audio can be adjusted by the obtained volume adjustment amount when the to-be-processed audio starts to be played, so that the play volume in the whole playing process of the to-be-processed audio can meet the preference loudness of the user by adjusting the play volume once. The adjustment of the playing volume of the audio to be processed refers to the adjustment of the volume of the electronic device for playing the audio to be processed.
Optionally, after the playing volume of the audio to be processed is adjusted by the volume control method in this embodiment, if the user adjusts the playing volume of the audio to be processed, the electronic device may continue to play the audio to be processed with the playing volume adjusted by the user.
The volume adjustment method in this embodiment may be executed when the current audio to be played is switched from other audio to the audio to be processed, or may be executed when the current audio to be played is switched from the audio to be processed to other audio, and the playing volume of the audio to be processed is adjusted by using the volume adjustment amount corresponding to the amplitude gear, so that the electronic device may automatically adjust the playing volume of the audio to be processed in a targeted manner, and the intelligence of volume control is improved.
According to the volume control method, the amplitude gear to which the signal amplitude of the audio to be processed belongs is acquired, then the volume adjustment amount corresponding to the amplitude gear is acquired, different amplitude gears correspond to different volume adjustment amounts, and then the volume adjustment amount is used for adjusting the playing volume of the audio to be processed, so that the playing volume of the audio to be processed is close to the target volume. The method can adaptively adjust the playing volume of the audio to be processed according to the amplitude gear to which the signal amplitude of the audio to be processed belongs, so that the playing volume of the audio to be processed is close to the target volume, and the intelligence of volume control is improved.
Referring to fig. 2, a flowchart of a method for controlling a volume according to another embodiment of the present application is shown, where the method for controlling a volume according to the present embodiment is applicable to an electronic device, and the method includes:
step S210: and obtaining the amplitude average value corresponding to each of the plurality of sample audios.
Wherein the plurality of sample audios may be different content types of audios, may be the same content type of audio, or may be a combination of the same content type of audio and different content types of audio. The source of the sample audio may not be limited, and may be derived from online real-time playing video, short video, or audio, for example.
As one way, the signal amplitude of each of a plurality of sample audios may be obtained, where a sample audio includes a plurality of frames of audios, and each frame of audio corresponds to one signal amplitude, and then the average value of the amplitudes of each sample audio is calculated according to the respective signal amplitudes.
Step S220: and acquiring the appointed volume level corresponding to each of the plurality of sample audios.
The volume level represents the volume of playing, the designated volume level represents the volume of playing frequently used (or preferred) by the user, and the designated volume levels corresponding to different sample audios can be different.
In an implementation manner, a volume level of each of the multiple sample audios at the playing end time may be obtained, where the playing end time may be understood as a time when a last frame of audio is played, the volume level at the playing end time may be understood as a volume of the last frame of the played audio, and the volume level at the playing end time may be defaulted to a volume level preferred by a user, so that the volume level of the audio at the playing end time may be used as an assigned volume level corresponding to the audio.
In another implementation, the volume level of the audio at the end of the playing may be detected, and if the volume level of the audio at the end of the playing is lower than a preset volume level (at this time, the volume level may be 0, i.e. a mute state, for example, when a user makes a trouble while listening to a song, the music may be played at the volume after being turned down until the end of the playing, or when the user sets the mobile phone volume to a mute mode while in a meeting, the music may be played in the mute mode until the end of the playing, at which time, even if the music is played, the sound cannot be heard), the preset volume level may be a critical volume level that enables the user to hear the sound, in this way, in order to ensure that the sample audio can be played at the playing volume according with the user's usage habit, the designated volume level for each of the plurality of sample audios may be obtained in a fully sampled manner. Specifically, the volume level corresponding to the sample audio in any playing time period may be obtained, and then all the obtained volume levels are averaged to obtain the specified volume level.
Optionally, if the user suddenly turns the playing volume low during the process of playing music, the time when the playing volume of the audio is turned down for the first time and the volume corresponding to each previous time may be obtained, and then the specified volume level corresponding to the audio is obtained in a full sampling manner, where the specific obtaining principle is similar to the above implementation manner, and is not described here again.
Step S230: and acquiring the target volume corresponding to the audio to be processed based on the amplitude average value and the designated volume level.
As one way, the user preferred volume may be constructed based on the amplitude average 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 the audio a played by the user at different time intervals may be recorded, for example, the volume of the audio a played by the user in the morning may be recorded as a1, the volume of the audio a played by the user in the noon is recorded as a2, the volume of the audio a played by the user in the evening is recorded as a3, and the average value of the amplitudes of the audio a is B, a user portrait may be constructed based on a1, a2, a3, and B, specifically, a1, a2, a3, and B may be input to a machine learning model, and a user preferred volume may be learned, in which manner, the user preferred volume may be used as a target volume corresponding to the audio to be processed.
Step S240: and acquiring an amplitude gear to which the signal amplitude of the audio to be processed belongs.
Step S250: and acquiring the volume adjustment amount corresponding to the amplitude gear.
As an embodiment, in order to facilitate that the playing volume in the playing process of the to-be-processed audio is in the loudness range preferred by the user, when the volume adjustment amount corresponding to the amplitude gear is obtained, the volume adjustment amount corresponding to the amplitude gear may be determined based on the target volume, specifically, the volume adjustment amount corresponding to the signal amplitude mean value of the amplitude gear may be determined based on the target volume (in this manner, the volume adjustment amount corresponding to the signal amplitude mean value of the amplitude gear may be taken as the volume adjustment amount corresponding to the amplitude gear), so that the playing volume of the to-be-processed audio after adjustment may be close to the target volume.
For example, in a specific application scenario, assuming that the target volume is-40 db, the signal amplitude of the audio to be processed is stepped into 6 steps, which are: -60db to-50 db, -50db to-40 db, -40db to-30 db, -30db to-20 db, -20db to-10 db, -10db to 0db, the signal amplitude mean value of each of the signal amplitudes of the 6 steps is-55 db, -45db, -35db, -25db, -15db and-5 db, then the volume adjustment amount corresponding to each of the 6 signal amplitude mean values can be determined as +15db, +5db, -5db, -15db, -25db and-35 db by combining the target volume, wherein the signal amplitude mean value of-55 db can be understood as the current reference playback volume of-55 db for the audio to be processed (it should be noted that the reference playback volume here can be understood as the approximate playback volume, assuming that the signal amplitude of the audio to be processed is-52 db, and since-52 db falls within the amplitude range of-60 db to-50 db, the volume adjustment amount corresponding to the signal amplitude mean value of-55 db of the amplitude range of-60 db to-50 db may also be used as the volume adjustment amount corresponding to the signal amplitude of-52 db), in order to make the playing volume of the audio to be processed close to the target volume, the playing volume of the audio to be processed may be controlled to be adjusted to +15db, so that the adjusted playing volume of the audio to be processed is-55 db +15db to-40 db, and the above-mentioned values are merely used as examples, and do not constitute a limitation to the present scheme, and other values may be used in actual implementation. Similarly, when the signal amplitude of the audio to be processed falls in other gears, the playing volume of the audio to be processed is adjusted by the volume adjustment amount corresponding to the other amplitude gears, so that the adjusted playing volume of the audio to be processed is the same as or close to the target volume, which is not described herein again. It should be noted that the value of the target volume in this embodiment may be changed, and the electronic device in this embodiment may determine the volume adjustment amount corresponding to the amplitude step based on the target volume in real time as the target volume is changed.
As another embodiment, the volume adjustment amount corresponding to the amplitude gear may be obtained from a preset table, where the preset table is determined according to the target volume. Specifically, a corresponding volume adjustment amount may be configured for the signal amplitude mean value of each amplitude gear, and the amplitude gear and the volume adjustment amount are stored in a table form after establishing a corresponding relationship. In contrast to the previous embodiment, in the present embodiment, when acquiring the volume adjustment amount, the incidence relation among the target volume, the amplitude gear and the volume adjustment quantity can be established, the volume adjustment quantity corresponding to the amplitude gear determined based on the target volume in real time is stored in a preset table form, in this manner, the preset table may store therein volume adjustment amounts corresponding to the magnitude steps determined based on target volumes of various values, when the volume adjustment amount corresponding to the amplitude gear is obtained, the volume adjustment amount corresponding to the amplitude gear can be directly obtained from the preset table in a table look-up manner, in other words, the acquiring process of the volume adjustment amount in this way is static, and the volume adjustment amount corresponding to the amplitude gear does not need to be calculated based on the target volume every time, so that the power consumption of the electronic equipment is saved.
Step S260: and adjusting the playing volume of the audio to be processed by using the volume adjustment amount so as to enable the playing volume of the audio to be processed to be close to a target volume, wherein the target volume is a value determined according to the habit of a user.
According to the volume control method, amplitude average values corresponding to a plurality of sample audios are obtained; acquiring an appointed volume level corresponding to each audio frequency in the plurality of sample audio frequencies; acquiring a target volume corresponding to the audio to be processed based on the amplitude average value and the designated volume level; acquiring an amplitude gear to which a signal amplitude of the audio to be processed belongs; acquiring a volume adjustment amount corresponding to the amplitude gear; and adjusting the playing volume of the audio to be processed by the volume adjustment amount so as to enable the playing volume of the audio to be processed to be close to the target volume. The method can adaptively adjust the playing volume of the audio to be processed according to the amplitude gear to which the signal amplitude of the audio to be processed belongs, so that the playing volume of the audio to be processed is close to the target volume, and the intelligence of volume control is improved.
Referring to fig. 3, a flowchart of a method for controlling a volume according to another embodiment of the present application is shown, where the method for controlling a volume provided in this embodiment is applicable to an electronic device, and the method includes:
step S310: and acquiring scene information to which the audio to be processed belongs.
The content types of the audio to be processed may be various, the scene information to which the audio to be processed of different content types belongs is different, and the scene information may be understood as the usage scene of the audio to be processed. For example, if the audio to be processed is rock music, the scene information to which the audio to be processed belongs may be a music festival scene, if the audio to be processed is light music, the scene information to which the audio to be processed belongs may be a learning scene, and if the audio to be processed is hypnotic music, the scene information to which the audio to be processed belongs may be a sleep scene. As a mode, the scene information corresponding to the to-be-processed audio of different content types may be preconfigured, and then the scene information to which the to-be-processed audio belongs may be obtained according to the content type of the to-be-processed audio.
As another mode, the scene information to which the audio to be processed belongs may be determined according to the position of the electronic device, where the electronic device may determine the position where the electronic device is located by combining the position information and the camera. For example, when it is detected that the electronic device is located in a public place such as a hospital or a subway (the public place advocates not to play out the volume of the electronic device so as not to disturb other users), it may be determined that the scene information to which the audio to be processed belongs is an earphone wearing playing scene, and if it is detected that the electronic device is located in a museum or the like, it may be determined that the scene information to which the audio to be processed belongs is a mute scene.
Step S320: and taking the volume corresponding to the scene information as the target volume corresponding to the audio to be processed.
Different scene information can be configured with different volumes correspondingly, and after the scene information of the audio to be processed is determined, the volume corresponding to the scene information can be used as the target volume corresponding to the audio to be processed.
Step S330: and acquiring an amplitude gear to which the signal amplitude of the audio to be processed belongs.
Step S340: determining a volume adjustment corresponding to the magnitude gear based on the target volume.
For a specific implementation process of determining the volume adjustment amount corresponding to the amplitude gear based on the target volume, reference may be made to the related description in the foregoing embodiment, and details are not repeated here.
Step S350: and adjusting the playing volume of the audio to be processed by using the volume adjustment amount so as to enable the playing volume of the audio to be processed to be close to a target volume, wherein the target volume is a value determined according to the habit of a user.
