Thank you for you quick reply, Jean-Marc. I have just used a human voice to replace the sine wave, but the result is like a broken voice after tens of seconds. Do you have some sample voice in .sw that I can test with? I want to have one set or a few sets of sample voice that work for my understanding and debugging. This is the output from echo_diagnostic.m in my human voice test: Far end to near end delay is 231 samples Delay looks OK. Drift estimate is 0.009063% (14 samples) There may be (not sure) excessive clock drift. Is the capture and playback done on the same soundcard?
