Hi Anton Thanks for the info... What if I use this function do I still need to sync the playback and capture? Assuming that the captured voice (*rec) already contains the echo which I need to cancel out... -------------------------------- void speex_echo_capture (SpeexEchoState *st, const spx_int16_t *rec, spx_int16_t *out) Parameters: st Echo canceller state rec signal

...quot; buffer. The sync is very important - because speex_echo_capture won't be able to remove clean echo frame that you didn't provide with speex_echo_playback. I hope I didn't messed up anything :) Best Regards, Anton A. Shpakovsky From: Christopher Adoremos [mailto:chrisadoremos at gmail.com] Sent: Thursday, September 30, 2010 11:52 AM To: Anton A.

Oh I overlooked that one.. Thanks Darren! Btw, I was wondering if anyone has tried using the echo canceller function of speex with other codec like g.711?

What is the highest quality audio data rate and sample rate Speex can support? -- Thanks <http://www.earnmailer.com/link/9e66612ae7944911> <http://www.earnmailer.com/alert/confirm/9e66612ae7944911> <http://www.earnmailer.com/> -------------- next part -------------- An HTML attachment was scrubbed...

Hi Is it possible to use only the speex echo cancellation module w/o using the speex codec? Here's the scenario: 1. I have my voice recorded in PCM audio file format 2. I want to cleanup the recorded voice by removing any echo included in the audio file/buffer 3. can I just use the ff APIs? - SpeexEchoState* speex_echo_state_init() - int speex_echo_ctl() - void speex_echo_capture()
