3) server sends to each client with algorithm processing module; The audio block that to cut apart is simultaneously distributed to each client successively; The Audio Processing algorithm of client call algorithm processing module is handled audio block successively, and the audio block after will handling then sends to server;
4) server becomes final output audio with the audio block set symphysis.
Further improvement as technique scheme:
Server will be imported the detailed step that audio frequency is divided into audio block according to the time and comprise in the said step 1): said server at first obtains the client terminal quantity in the LAN; Obtain the T.T. of input audio frequency then; To importing cutting apart T.T. of audio frequency, obtain the quantity audio block identical then with client terminal quantity according to client terminal quantity.
The Audio Processing algorithm of client call algorithm processing module comprises the detailed step that audio block is handled successively in the said step 3): client at first detects video card and whether supports general-purpose computations, and the Audio Processing algorithm of the general-purpose computations interface interchange algorithm processing module if video card is supported the general-purpose computations ability through video card is handled audio block successively; The Audio Processing algorithm that calls algorithm processing module through central processing unit if video card is not supported the general-purpose computations ability is handled audio block successively.
The Audio Processing algorithm that calls algorithm processing module through central processing unit comprises the detailed step that audio block is handled successively: said client is at first obtained the core and the core of processor and is supported that number of threads obtains hardware computing number of threads; Hardware computing number of threads is that unit is divided into the sub-audio piece with the second with audio block then; Then the sub-audio piece is distributed to each hardware computing thread respectively, and the sub-audio piece after after all sub-audio pieces dispose, will handling makes up the audio block after obtaining handling.
The present invention has following advantage: the present invention is used to carry out the algorithm processing module of concrete Audio Processing algorithm through the server sets of LAN; And will import audio frequency and be divided into audio block according to the time; Server sends to each client with algorithm processing module; The audio block that to cut apart is simultaneously distributed to each client successively, and the Audio Processing algorithm of client call algorithm processing module is handled audio block successively, and the audio block after will handling then sends to server; Server becomes final output audio with the audio block set symphysis; Can make full use of the computational resource of LAN computing machine, can realize that the parallel audio of LAN is handled the advantage that the local Audio Processing is efficiently quick, easy to use.
