Hi all, I am using the latest version of Speex 1.2rc and I have ported it onto a Fixed point DSP (DM642) the echo cancellation works great, however the AGC zeros the output buffer when calling preprocessor routine, I have executed the fixed point AGC patches that I found on this forum, however I still have this issue. Can anyone shed light on this, if so I would be eternally grateful. James -------------- next part -------------- An HTML attachment was scrubbed...
