Abstract

The invention discloses a gain adjustment method, comprising: obtaining the average power value of an audio file based on a time-domain signal, and a preset power value at each level of volume; according to the average power value and the preset power value, calculating obtaining an expected gain value; calculating a pre-adjusted power value according to the average power value, the expected gain value, and a preset reference power value; performing gain adjustment on the audio file according to the pre-adjusted power value. The invention also discloses an audio device and a computer-readable storage medium. The invention can prevent the user from frequently manually adjusting the volume to hear the audio file clearly or from damage to the auditory system due to a sudden loudness increase, thereby improving the user's listening effect.

Description

technical field [0001] The present invention relates to the field of audio technology, and in particular, to a gain adjustment method, an audio device and a computer-readable storage medium. Background technique [0002] When users listen to music through an audio device such as a player, they usually encounter the situation that the sound of some songs is too low, and the volume needs to be manually increased. When the next music is automatically played, the sound will suddenly become louder, resulting in loudness. Too large to 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 frequently, which is not only inconvenient to operate, but may also cause damage to the user's hearing system. In addition, if you simply use the volume "+" key to increase the volume, it may cause overload due to the sudden change of individual large signals, resulting in nonlin...
