Hello! I'm programer in the construction company. And I have to develop applications which has to use speex codec. The main problem is realization of echo cancellation. The other day I installed LinPhone software, which uses the speex echo cancellation. I connected two computers in my office. One of them had earphones with microphone and second - speaker phone in notebook. But the echo cancellation function didn't make any effect. I heard echo of my voice in earphones on the first computer. Can you help me? Why it doesn't work. Some people in forums tell that it have to work fine. I use LinPhone for Windows and Linux operation systems. Thank you for help. -------------- next part -------------- An HTML attachment was scrubbed...
