Problems solved by technology

[0005] However, the above method still has the following problems: one, when recording different songs, the volume selection will be different, so even if the player sets the same volume, different songs will show different volumes; The volume is not the only determinant of the final output loudness; 3. The attenuation of the high frequency part can easily destroy the music effect

Abstract

The invention relates to a method for playing an audio file. The method for playing the audio file comprises the steps that the audio file is scanned so that a volume gain value can be obtained and the gain value can be written in the audio file; the gain value stored in the audio file is read; the volume output when the audio file is played is adjusted according to the gain value; the audio file is output. According to the method for playing the audio file, the audio file is scanned, so that the volume gain value of the audio file is obtained, the volume output when following different audio files are played is unified, impact, caused by volume change generated when different audio files are switched, on a user is reduced, and the hearing of the user is protected. In addition, the invention further provides a device for playing the audio file.

Description

technical field [0001] The invention relates to audio processing technology, in particular to an audio file playing method and playing device. Background technique [0002] Music has been liked by numerous users as one of the most popular media on the Internet, and many users use various player software to listen to music. In order to protect the user's hearing, some existing music players provide a hearing protection function. [0003] Generally speaking, the existing hearing protection includes the following two methods: one, protect hearing by monitoring and adjusting the volume set by the player; two, carry out hearing protection by directly weakening or eliminating the high frequency part of music. [0004] The first method is mainly to protect the listener’s hearing in terms of volume control. The consideration of the second method is that at the same volume, songs with strong high-frequency parts will sound better than songs with weaker high-frequency parts. "Harrin...
