One question did you use these 2 functions speex_echo_playback speex_echo_capture No, I didn't use them. I use my own code to...

Hi, I've sorted the performance issues i had in a previous post. Now the AEC runs but does not cancel any echo. I have a scenario where i have a single thread processing thread messages WOM_DONE and WIM_DATA which tell me when Windows Mobile OS has played the buffer or received the buffer respectively. Anyone any ideas how to sync the mic and the speaker. Any tips would be useful. Thanks

Hi Jean Marc, We are running the speex echo canceller code on a Windows Mobile smartphone using a TI OMAP 201MHz 850. We are making voip calls and audio is working without echo canceller code. Simply adding the following 2 functions whether the echo cancellation is wired in (ie we use the output frame ) or not performance becomes terrible. Note 2 separate threads are used to handle audio.
