Embodiment Construction

[0041] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] like figure 1 As shown, the audio device of the present invention includes: a processor 1001 such as a CPU, a user interface 1002 , a memory 1003 , a communication bus 1004 and a speaker 1005 . Wherein, the communication bus 1004 is used to realize connection and communication between these components. The user interface 1002 may include an input unit. Speaker 1005 is used to play audio files.

[0043] The memory 1003 can be a high-speed RAM memory, or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1003 may also be a storage device independent of the foregoing processor 1001 .

[0044] Those skilled in the art can understand that, figure 1 The audio device shown in the audio device does not constitute a limitation to the audio device, and may include more or less compo...

Abstract

The invention discloses a gain adjustment method, which comprises the following steps of: obtaining an average power value of an audio file based on a time domain signal and a preset power value undereach level of volume; obtaining the average power value of the audio file based on the time domain signal; and obtaining the preset power value under each level of volume, calculating an expected gain value according to the average power value and the preset power value; calculating a preset power value according to the average power value, the expected gain value and a preset reference power value; Gain adjustment of the audio file is performed according to the preset power value. The invention also discloses an audio device and a computer-readable storage medium. The invention can avoid thedamage of the auditory system caused by the sudden increase of the loudness or the manual adjustment of the volume of the audio file by the user, thereby improving the auditory effect of the user.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to a gain adjustment method, audio equipment and a computer-readable storage medium. Background technique [0002] When a user listens to music through an audio device such as a player, the sound of some songs is usually too low, and the volume needs to be increased manually. When the next music is automatically played, the sound will suddenly become louder, resulting in loudness. Excessively large and cause hearing discomfort. Especially when the source of the sound source is not uniform or the playback software is different, it is necessary to manually adjust the volume, which is not only inconvenient to operate, but may also cause damage to the user's auditory system. In addition, if the volume is increased simply through the volume "+" key, it may cause overload due to sudden changes in individual large signals, resulting in nonlinear distortion, thereby affecting the user's lis...
