Abstract

The present invention provides an audio processing method and device, which relate to the technical field of audio processing. The method includes: acquiring M times of alternate access audio data in the buffer initial audio data, and N times of alternate access audio data in the buffer real-time audio data For the audio data, M first network jitter estimates and N second network jitter estimates can be obtained, and the maximum first network jitter estimates are respectively determined among the M first network jitter estimates and N second network jitter estimates value and the maximum estimated value of the second network jitter, the network state can be determined according to the maximum estimated value of the first network jitter and the maximum estimated value of the second network jitter, and the audio data in the buffer is processed according to the network state, thereby reducing the terminal receiving audio frequency data delay.

Description

technical field [0001] The present invention relates to the technical field of audio processing, in particular to an audio processing method and device. Background technique [0002] With the rapid development of science and technology, the application and technology of audio playback are becoming more and more extensive. After users install the player on the terminal, they can listen to audio online. When the terminal receives audio data, the semantic integrity of the audio data is very important. [0003] In related technologies, the transmission of audio data is usually affected by network jitter factors during transmission. In order to reduce the impact of network jitter in audio transmission, buf (buffer, buffer) is usually introduced. In the server The buffer stores the audio data, the buffer of the server sends the audio data to the terminal, and the terminal can receive the audio data. [0004] However, when a large amount of audio data is stored in the buffer, the ...
