Hi,   I am very glad to enter this mail list. i am a new guy,i am interested in speech coding.so is there anybody working on this ? please contact me,thank you.i am studing on fixed codebook search. and i have read almost all the articals(including patent on this) about codebook search. but i found that all the suboptimize methods have their own flaw.  could anybody have some comments on this?thank you very much.   To today's topic:   1、i am not familiar with arm platform,so i am sorry i can not help you.

People at different distances from the server will have a slightly different round trip time. Do you think if using a large tail or something we can get near perfect AEC? The same as you get with a hands free phone perhaps? Does it still sound like worth a try? Is Speex AEC as good as it gets or would it be worth contacting some vendors of such software?

You'll need to try, but to have any chance of working, the following conditions must be met: 1) No codec must be used in the echo path (maybe G.711 is OK) 2) There must not be any drift in the sampling clocks 3) There must not be any audio samples lost on the echo path Jean-Marc --------------------------------- Yahoo!
