step S101, when detecting that the terminal equipment plays the sound source, acquiring audio information of the sound source with preset length.
The terminal equipment can play the sound source through the installed third-party application program or the audio and video playing software carried by the system. The method mainly comprises the steps of obtaining, decoding, outputting and the like of the sound source file. Illustratively, the obtained sound source file may be a multicast stream received through a network, or may be an audio/video file locally stored by the terminal device; after the sound source file is obtained, loading the sound source file into a memory buffer area; the method comprises the steps of decoding a sound source file loaded into a memory buffer area, before decoding starts, if the sound source file simultaneously contains video data, separating the audio data from the video data, and inputting the separated audio data into an audio decoder, wherein the audio decoder is mainly used for reading the audio data in the memory buffer area to obtain a digital audio signal and converting the digital audio signal into an analog audio signal, and a playing device of a terminal device plays audio according to the analog audio signal. In one embodiment, when it is monitored that a sound source playing event is triggered, it is determined that the terminal device starts playing a sound source, where the triggering event may be that a playing button displayed in a touch screen is pressed, or that a playing device of the terminal device, such as a speaker, starts playing sound, and the terminal device is determined to play the sound source.
And when detecting that the terminal equipment plays the sound source, acquiring audio information of the sound source with the preset length. In one embodiment, the digital audio signal decoded by the audio decoder may be sampled to determine the audio information corresponding to the sound source, where the preset length may be 3s, 5s, 10s, or the like. In another embodiment, an original file of a currently played sound source may also be obtained, and audio information with a preset length corresponding to the sound source may be determined through parsing of the original file. In another embodiment, for example, in an Android system, the audio information of the sound source may be obtained through an Android.
And step S102, determining the amplitude difference in the audio information with the preset length.
The amplitude refers to the maximum distance from the original position in the vibration process of the object, the loudness of the sound heard by human ears is related to the amplitude of the sound source, and the loudness is stronger when the amplitude is larger. In one embodiment, the digital audio signal decoded by the audio decoder may be sampled to obtain amplitude information, wherein the amplitude information may be composed of a plurality of amplitude values, and the amplitude difference may be determined accordingly according to the obtained plurality of amplitude values. For example, taking 3s as an example, in a sound source played within a time length of 3s, the maximum amplitude value and the minimum amplitude value obtained by corresponding to a plurality of amplitude values in the audio information are recorded, and the difference between the maximum amplitude value and the minimum amplitude value is determined as the amplitude difference of the audio information with the preset length.
In one embodiment, the audio information is determined once every predetermined time (e.g., 1s, 3s, or 10s) when the audio source is detected to play, or in real time, the amplitude of each frame of the audio information is determined, and the amplitude difference is determined when the predetermined length is reached. Specifically, the acquiring the audio information of the sound source includes: the acquiring the audio information of the preset length of the sound source comprises: acquiring audio frame information of the sound source with a preset length; correspondingly, the determining the amplitude difference in the audio information with the preset length includes: and determining the amplitude difference in the audio information with the preset length according to the audio frame information. Illustratively, when a sound source playing is detected, the sound source file is analyzed to obtain a sequence of audio frames, and a corresponding amplitude is determined for each frame under the audio information with a preset length, so as to determine an amplitude difference.
And step S103, judging whether the amplitude difference meets a preset condition, if so, executing step S104, and otherwise, executing step S105.
In one embodiment, the amplitude difference satisfying the preset condition includes: the amplitude difference is greater than a preset amplitude difference. An exemplary such preset amplitude difference may be 0.2 db. When the amplitude difference is larger, the difference between the highest volume and the lowest volume of sound is larger when the sound source plays, so that a user can hear the sound with larger fluctuation and more abrupt sound volume.
And step S104, adjusting the amplitude of the sound source.
In one embodiment, said adjusting the amplitude of said audio source comprises: the amplitude of the audio source greater than a first amplitude threshold and less than a second amplitude threshold is adjusted.

Optionally, after determining that the sound source meets the adjustment condition, modifying data representing amplitude information in the obtained audio data by analyzing the sound source file, and encapsulating the modified data after the modification is completed, wherein the amplitude of the sound source is correspondingly increased when the corresponding sound source file is buffered and played; in the process of decoding the sound source playing, the obtained digital audio signal is analyzed to obtain amplitude data, and the amplitude data is multiplied by the corresponding adjusting coefficient to change the amplitude, so as to adjust the volume of the sound source. Therefore, the volume of the sound source is adjusted on the premise that the original volume of the terminal equipment system is not changed, the adjustment process can be carried out before the sound source file does not enter the buffer area so as to reduce the playing load, and the adjustment process can also be carried out aiming at the sound source content in the buffer area so as to improve the adjustment efficiency.
In another embodiment, the amplitude of each frame of the audio source is adjusted. Specifically, in the adjustment process, different amplitude adjustment coefficients are allocated for different amplitude sizes of each frame to perform corresponding adjustment, and for example, the specific correspondence relationship may be as shown in the following table:
TABLE 1
| Amplitude of vibration | Coefficient of regulation |
| Greater than-3 db or less than-50 db | 1 |
| Less than-10 db and greater than-50 db | 2 |
| Less than-3 db and greater than-10 db | 1.5 |
As shown in Table 1, when the amplitude of an audio frame is greater than-3 db or less than-50 db, its gain is not adjusted; when the amplitude is less than-10 db and greater than-50 db, the amplitude is a high amplitude region to which a gain coefficient of 1.5 is assigned, and when the amplitude is less than-10 db and greater than-50 db, the amplitude is a medium amplitude region to which an amplitude coefficient of 2 is assigned to significantly increase the amplitude of the portion of the amplitude.
And step S105, ending.

The adjusting the amplitude less than the second amplitude threshold to the second amplitude comprises: the amplitude less than the second amplitude threshold and greater than the third amplitude threshold is adjusted to a second amplitude. As shown in fig. 2, the scheme is as follows:
step S201, when detecting that the terminal equipment plays the sound source, acquiring audio information with a preset length of the sound source, and determining an amplitude difference in the audio information with the preset length.
Step S202, judging whether the amplitude difference meets a preset condition, and if so, executing step S203.
Step S203, determining whether the amplitude of the sound source is greater than a first preset amplitude threshold, if so, executing step S204, and if not, executing step S205. Illustratively, the first preset amplitude threshold may be-2 db.
Step S204, the amplitude is adjusted to the first amplitude. Illustratively, the first amplitude may be any value from-4 db to-10 db.
Step S205, determining whether the amplitude of the sound source is smaller than a second preset amplitude threshold, if so, executing step S206, and if not, executing step S208. Illustratively, the second preset amplitude threshold may be-30 db.
Step S206, judging whether the amplitude of the sound source is larger than a third preset amplitude threshold value, if so, executing step S207, and if not, executing step S208. Illustratively, the third preset amplitude threshold may be-50 db.
Step S207, the amplitude is adjusted to the second amplitude. Illustratively, the magnitude of the second amplitude may be-20 db.
And step S308, ending.
Therefore, in the process of adjusting the amplitude of the sound source, the amplitude meeting the adjusting condition is adjusted to a fixed amplitude interval, the amplitude adjusting efficiency is improved, meanwhile, the amplitude information corresponding to the noise is not adjusted, and the problem that the noise is synchronously amplified and then the playing quality of the sound source is influenced is solved.

In one embodiment, the corresponding volume adjustment information is determined based on the amplitude of the audio source. Illustratively, when the amplitude of the sound source is small (e.g., -40db), the corresponding volume up information is determined, and when the amplitude of the sound source is large (e.g., 0db), the corresponding volume down information is determined. Specifically, in one embodiment, the volume increase or volume decrease information is the corresponding target volume value. Illustratively, the terminal device is divided into 18 adjustable levels from mute to maximum volume, each level corresponds to a volume value, the target volume value corresponding to the volume reduction information may be 3 or 4, the target volume value corresponding to the volume increase information may be 14 or 15, when the determined amplitude of the sound source is smaller, the volume value is correspondingly increased to 14 or 15, and when the determined amplitude of the sound source is larger, the volume value is correspondingly reduced to 3 or 4.
