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...

...ame in "out" 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.

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()

...nction but you will have to sync playback and capture streams by yourself. I've used GSM, iLBC and Speex codecs with Speex AEC and it works fine. Best Regards, Anton A.

Hi All, I am working on VBR fixed point conversion for our DSP processor and in the algorithm the MIN_ENERGY and some more terms which I am not able to understand how those numbers are derived. Can some one help me with some documentation on algorithm discription of VBR?. Regards, -Prasad
