Description
Technical field
The present invention relates to a kind of data processing equipments, more particularly to a kind of audio processing system and method.
Background technique
With the development of VOIP (Vocie Over Internet Protcol), VOIP terminal traffic is more and more, function
Also it becomes increasingly complex, and DSP (Digital Signal Processing, digital signal processor) plays the sound of VOIP
This key player of processor, if some business of VOIP terminal are realized, without traffic affecting normal use, it is necessary to
DSP supports audio mixing (mixing multi-acoustical).
In VOIP terminal, there are mainly two types of the audio mixings of DSP, the first is that network side sound and local sound carry out audio mixing
(such as call waiting) is for second that the sound of network side carries out audio mixing (such as tripartite talks business).For second
It is that all DSP are supported, and the first is primarily referred to as the audio mixing of call sound and some Tone sounds.The first supports that DSP is mixed
The realization of sound be operation layer specify the Tone sound to be played tell DSP, DSP after receiving it is internal have a set of mechanism go tone sound and
Conversation voice carries out audio mixing broadcasting.It, can not by will lead to a period for playing tone sound if DSP not can be carried out audio mixing
Hear call sound.
In VOIP terminal, a variety of, the different business of the type of Tone sound, the Tone sound of broadcasting is different, and Tone sound is broadcast
It puts and is mainly controlled by frequency and playback period (playing rhythm).Such as the frequency of call waiting tone is 425HZ, it is continuous to play
4 times, the time played every time is call waiting tone 100ms, then mute 2S (here a Tone sound be by call waiting tone and
Mute composition).From here it will be seen that the broadcasting of Tone sound needs 4* (0.1+2) S in total, in mute 4*2S this period
Also the resource of DSP is occupied, the efficiency of digital signal processor is caused to reduce.
Summary of the invention
Based on this, it is necessary to provide a kind of audio processing system and method that Digital Signal Processing is more efficient.
