Does anyone have information or successfully connected Asterisk to TalkMaster from Digital Accoustics? Thanks, Jerry

Hi list! I have a strange echo problem. Two days ago I setup * 1.0.6. at a friend of mine. Just an * server and for outbound calls wengo.fr was used to place calls via sip. He had a strange echo on the line I didn't experience on my setup. Today I upgraded my asterisk 1.0.5 to 1.0.6 and suddenly I have an echo too on sip calls thru wengo!! I already verified wengo was not the source of

...ng some intelligence to correlate their 'Q' values to actual perceived quality, rather than some arbitrary pixel difference value. That way, fixed-Q could actually mean something useful. I suspect that audio codecs, particularly Vorbis, do this intrinsically, because their internal psycho-accoustic models tend to be rather complex. In the video world, for reasons that elude me, this is not the case. I know of no codec that incorporates any useful psycho-visual model into its encoder (though there are encoding apps that sit on top of codecs that claim to do this). IMSHO, this should be a...

Hi All, Currently I am investigating how interesting OGG is for me. The most important requirements are: - Decoding on embedded hardware, ARM7 or ARM9. - Mixing multiple audio streams/files on embedded hardware First of all how difficult is it to decode OGG on an ARM7/9 processor? I read that OGG decoding needs floating point support? Secondly I would like to know how many MIPS are needed to

...nussen on the filter while it is adapting. If I do that (that seems my biggest problem), it looks like the tone gets modulated by the echo. These things are my own experiences. I am not a wizard like Jean-Marc Valin :-(. My setup is maybe a bit different. I use headsets, which unfortunately have accoustic feedback, but they are not so loud. At my setup the echo is created by an analog modem connected to an analog line. The signal I get from the modem contains the voices of both the caller and the callee in almost the same volume. The biggest problems I have encountered so far: having clear tones...

Hello, I am testing speex 1.1.6's echo canceller. I am using testecho.c, with a few modifications to get it to run on Windows. My problem is that I am unable to get the echo cancellation to work correctly. I am working on an audio conferencing software, and one issue we have is sometimes the microphone picks up what is being played through the headset, resulting in an echo of the other

I called Digium today and hear some neat nifty music on hold that isn't included with Asterisk.. anyone have any idea what it is.. and where I can get it (if it's in the public domain)?
