Problems solved by technology

[0003] In practical applications, some audio files have large rhythm fluctuations and volume changes. For example, after a gentle and low music, there is a sudden transition to rapid and high-pitched music. At this time, the sudden increase in rhythm and volume not only increases the audio power consumption of the terminal device It may also cause damage to the user's hearing, which is not conducive to the user's health

Abstract

The embodiment of the present invention discloses a sound effect processing method and a terminal device, wherein the sound effect processing method may include: when the terminal device plays an audio file, detecting the maximum volume difference of an audio segment of the audio file currently read, the The maximum volume difference is the difference between the maximum volume and the minimum volume of the audio segment; if the maximum volume difference is greater than the preset difference, determine the first sub-segment in the audio segment whose volume is greater than the first preset volume ; Decrease the volume of playing the first sub-segment. By adopting the embodiment of the present invention, the playback volume of audio clips with excessive volume in the audio file can be reduced in advance, so as to protect the user's sense of hearing and reduce the audio power consumption of the terminal device.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, in particular to a sound effect processing method and a terminal device. Background technique [0002] With the development of smart terminal technology, various smart terminals emerge in an endless stream on the market, and the functions and applications of smart terminals are becoming more and more abundant. Among them, the audio playback function is a basic function that most smart terminals have. Many applications in the terminal need to call the audio module for audio playback, such as playing game sound effects, music, video sound effects, etc. [0003] In practical applications, some audio files have large rhythm fluctuations and volume changes. For example, after a gentle and low music, there is a sudden transition to rapid and high-pitched music. At this time, the sudden increase in rhythm and volume not only increases the audio power consumption of the terminal de...
