Abstract

The embodiment of the invention provides an audio processing method, apparatus and device, and a storage medium. The method comprises the steps of obtaining a to-be-played audio data stream; detecting whether a data variation between adjacent audio data greater than a preset threshold exists in the audio data stream to be played, and if yes, performing gradual change processing on the target audio data by adopting a preset gradual change step length to obtain detected audio data; wherein the target audio data is one of two adjacent audio data of which the data variation is greater than a preset threshold value; and transmitting the detected audio data in the audio data stream to be played to a player. According to the mode, the possibility that pop sound exists when the audio data is played is reduced.

Description

technical field [0001] The present application relates to the field of audio technology, and in particular, to an audio processing method, apparatus, device, and storage medium. Background technique [0002] Pop sound refers to the plosive sound produced when the audio starts and stops playing, and it is also a kind of noise. The noise is very sharp, which brings a very poor hearing experience to the user, and will damage the user's hearing in the long run. Most of the pop sounds are generated by hardware. The audio device will generate a transient impact at the moment of power-on and power-off, thereby generating pop sounds. This kind of pop sounds is usually modified by modifying the power-on sequence of the codec, or in the circuit. Adding capacitance can solve it. [0003] But there is also a pop sound that is due to a sudden change in the audio data, and the audio data changes from a stable value to another value instantaneously, for example, from a stable value to a ...
