Abstract

The embodiment of the invention relates to a volume adjusting method and a volume adjusting device. The method comprises the steps of: reading a current audio file; obtaining the recognition information of the audio file from the current audio file; inquiring the volume relative gain value of the audio file from a volume relative gain value record list according to the recognition information of the audio file; and adjusting the volume gain of a player according to the volume relative gain value of the audio file. The volume adjusting method and the volume adjusting device provided by the embodiment of the invention are used for automatically adjusting the volume gain of the player by inquiring the volume relative gain value of the audio file from the volume relative gain value record list.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of audio processing, and in particular, to a volume adjustment method and device. Background technique [0002] When the user uses the player to play an audio file, if the audio file contains volume information, the volume of an audio file may be inconsistent with other files, or the user may have a louder or louder sound for an audio file. The need for a smaller sound causes the user to re-adjust the volume of the player when listening to the audio file, and then adjust it back when listening to the next audio file, which is cumbersome. [0003] The way that adopts at present is, adds feedback circuit in the audio frequency output part of player, makes central processing unit, CPU (CentralProcessingUnit) carry out automatic adjustment volume gain amount according to the size of output volume, thereby reaches the purpose of automatic adjustment. But after this automatic adjustment of t...
