Problems solved by technology

[0003] In the existing audio volume equalization gain method, in order to avoid "cracking sound", the audio player will determine the maximum gain coefficient of the audio file according to the maximum volume value of the audio file, but in some cases the maximum volume value of the audio file is only accidental Appears, directly using the maximum gain coefficient determined according to the maximum volume value to increase the volume of the audio file is very limited, and the maximum volume gain effect cannot be achieved

Abstract

The embodiment of the invention discloses an audio volume gain method. The method comprises the steps of: acquiring sampling volume peak values of a target audio file; determining an effective volume range of the target audio file according to a volume value range where each sampling volume peak value of the target audio file is located; determining a volume value corresponding to the effective volume range as an effective volume peak value of the target audio file; and determining a maximum volume gain coefficient of the target audio file according to the effective volume peak value of the target audio file. The embodiment of the invention also discloses an audio volume gain device. By adopting the audio volume gain method and the audio volume gain device, the audio volume gain can be effectively improved.

Description

technical field [0001] The invention relates to the field of audio processing, in particular to an audio volume gain method and device. Background technique [0002] Because different audio sources, acquisition methods, recording methods, etc. will cause a large difference in the volume of different audio files, in order to avoid the sudden loud or suddenly low sound when playing different audio files, the user can choose to turn on the audio The volume equalization function of the player performs equalization gain on some audio files. [0003] In the existing audio volume equalization gain method, in order to avoid "cracking sound", the audio player will determine the maximum gain coefficient of the audio file according to the maximum volume value of the audio file, but in some cases the maximum volume value of the audio file is only accidental It appears that directly using the maximum gain coefficient determined according to the maximum volume value to perform volume gai...
