...suppression scheme. Skype seems to do a reasonable job, though. It is difficulty to measure the accurate difference between two sampling rate by a software in a short time. So I don't believe Skype do some kind of resynchronise or re-sampling work. From: Guilherme Balena Versiani <guibv at comunip.com.br> > Yeah, the ADC and DAC work at different rates.

...ng speaker input as having direct access into what has been played thru speaker. (ASIO Soundcard provides interface for that) So if I am remebering correctly, with data from Mic and Speaker in sync, speex AEC should do the job.

I actually forgot to mention that I'm using ultra-wideband mode, but seems like you understood that anyway. Is this true that Speex echo cancellation only performs well in narrowband mode !? I've been using 100 ms as the default tail length. I don't know what the ideal tail length would be. I have tried shorter and longer tails but it hasn't made any difference. Does

I'm being PHBed into a VOIP project, and Speex sprang to mind. Bandwidth is going to be a fairly serious issue for us. With regards to a Speex enc/decoder, I was wondering: Rick Kane and David Siebert have already asked about this, but seem to have gotten very different responses - the former a call to arms, and the latter a "well, if you do it, it'll get done." What's the

Hi Andrey, May be that we don´t understand. I need to transform speex to pocket pc platform. The Windows API is different to Pocket Pc API. Some IDEs that help us to create code for pocket pc, for example, are Visual C++ 3.0 embedded or Visual Studio.Net. Christian will develop this work with Visual C embedded. If you can develop this work quickly or you can guide me step by step, i would be very
