1) Everytime a participant speaks there is a echo for a short duration (maybe a word or two) but as the participant continues to speak without a any break the echo is 95% cancelled (i.e there is a feeble echo still present if observed very carefully). 2) The moment the participant stops / pauses speaking and start talking again, scenario 1 is repeated as if the echo state has been re-initialized

I have build celt with FIXED_POINT option (latest 0.6.1 as well as from the git repo) on windows. However I am not getting a valid output (all samples are saturated) when I try to decode with this version. The input file was encoded with the same fixed point version. Does fixed point version work at all? Following are the command line settings; Samplerate; 48000 Channels: 2 Framesize: 256

...card have an own internal buffer which can introduce some anomalies in the audio playing, like a small pause or an audio cut. Most of these anomalies are very difficult to be heard but they are important for the synchronization I hope that this could help. Marco 2010/5/10 Elston Sa <jose at rebaca.com>: > Yes.

Yes. I guessed that too, however I am not sure why it keeps repeating every time the user stops / pauses and starts speaking again in a single session. I am using a laptop with standalone speakers. For echo cancellation to work one has to make sure that the ref and echo buffers are synchronized. I guess this is the most common problem. -Elston -----Original Message----- From: Anton A.
