Abstract

The invention provides an audio playing processing method. The audio playing processing method comprises the steps of calculating a difference value between a theoretical sampling point number and anactual sampling point number of audio data when each audio frame is played; when the sampling point number difference value of the current audio frame is greater than the sampling point number difference value of the previous audio frame, reducing the sampling rate of the audio data, or when the sampling point number difference value of the current audio frame is less than or equal to the samplingpoint number difference value of the previous audio frame, improving the sampling rate of the audio data; so that a local device can stably play the audio data transmitted by the remote device. According to the method, the actual sampling rate is set to be lower than the original sampling rate in the initial stage of audio playing, so that a buffer area can start audio playing without caching more audio data, and the problem of relatively large sound delay during audio playing in the prior art is solved; by reducing the playing sampling rate, the playing time of the current data is prolonged,the problem of audio lag is reduced, and the problem of lag due to the fact that the far-end audio data does not reach the equipment end in time in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to an audio playback processing method. Background technique [0002] With the continuous development of digital music technology, users have higher and higher requirements for the transmission speed of music or video. When the audio playback is just started, due to the influence of various factors, the sound output will be slow, and there will be staccato, Caton and other phenomena affect the product experience. In order to reduce this impact, the market mainly optimizes network transmission and local buffering technologies. However, this method often causes audio playback freezes due to system stability fluctuations, affecting user experience. Contents of the invention [0003] The present invention provides an audio playback processing method, which solves the problems in the prior art that the sound of the audio playback is slow, staccato sound, and stuttering during...
