Abstract

The embodiment of the invention belongs to the technical field of communication, and provides a sound effect adjustment method, a sound effect adjustment device and a mobile terminal. The method comprises steps: corresponding target music features are extracted from audio signals of a target music file; music genre information matched with the target music features are searched; and when the target music file is played, sound effect configuration information corresponding to the music genre information is loaded. The embodiment of the invention solves the problem that as the lack of the music genre information of the music file, when the music file is played, the corresponding sound effect configuration information can not be loaded. The music genre information recognition rate is improved, corresponding sound effect configuration information can be automatically loaded according to the music genre information of different music files, and the operation experience and the music experience of the user are enhanced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and mobile terminal for adjusting sound effects. Background technique [0002] With the popularity of electronic devices, people are more and more inclined to use electronic devices to play music. In order to improve the user's sense of hearing, various sound effect configuration information is often built into the playback device to adapt to different music genre information. When the user plays music files of different genres, it is necessary to frequently change the sound effect configuration information of the playback device to adapt to the currently played music file, so as to achieve a better playback effect. [0003] At present, most playback devices select the corresponding sound effect configuration information by reading the music genre information in the attribute information in the music file. For example, if the music genre informati...
