PocketPC 2005/echo canceller

get the mode from a incoming speex stream
On Wed, 6 Dec 2006, lianghu xu wrote: > Hi Jean-Marc, > > I remember you said that the SDP tells the mode information. Right. But a decoder like speex can always be configured from information contained in the incoming stream. That makes your application more interroperable.

...f the frame is in wideband, then this will be followed by a bit of wideband information that starts with a bit set to 1 (narrowband starts with a bit set to 0). Have a look at what the Speex decoder does. You may actually want to have similar code in a "null decoder".

DC component coming back after AGC
I'm getting confused, what's the problem exactly? The AGC doesn't remove the DC or it adds one?

complie speex on pxa-270
Hi, Speex-dev: ? I have some problems about complie speex on pxa-270. I use libspeex.so.1.4.0 at my platform after complie speex and all function is ok, but the cpu loading is 99%. How can i do to reduce the cpu loading? ? note: 1. My Platform are os: linux 2.6.19 , cc: gcc-2.95.3 , cpu: pxa-270, ogg: libogg-1.1.3, speex: speex-1.2beta3 2.

Abuot the Bug of Speex 1.2beta1
Dear Sir/Miss: I'm very sorry to bother you,but I've found a bug in the Speex,Version 1.2beta1,and also I've have some questions. I'm deeply impressed by the work you have done in the coding and decoding of speech signal.But when using speex,I encoutered a bug,that is when in 32K mode,the window size is still 200 samples,but not 400 samples,the bug will bring the problem of

Is 17 dB ERLE normal?
Hi We are working on a speaker phone system using PJSIP and Speex Speech processing API on an ARM platform. Currently we have spent about a month on getting the AEC to work properly and we have worked through the most common causes of problems (such as clock drift, synchronization problems and non-linearity's in echo path). Now we achieve ERLE of about 17 dB which tells me that the AEC is

Stream Synchronization for Echo Cancellation
...ike it is the echo canceller. Even a drift by one sample means that the echo canceller needs to re-adapt. So as soon as the (local) clocks aren't *perfectly* synchronised, the echo cancellation performance goes down to a point where it's mainly unusable.

Actually, the only way it could be somewhat related to Speex is if one of the symbols in Speex clashes with system functions, though I think it's unlikely.

Multichannel echo cancellation
Dear all, I have just implemented a gstreamer plugin for the Speex AEC, but now I would like to extend it to a multichannel echo cancellation I have been searching documentation about that but I could not find it Where it is? If it doesn't exist? Could you add a short example showing how do you think it should work? or It's "just" necessary to: init the multichannel echo
