Echo after upgrade * 1.05 -> 1.06
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

Fixed Quantizer - Fixed Quality
...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...

OGG decoding/multi-channel mixing
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

FW: Echo Cancellation
...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...

Xen secure display
What solutions are available to provide a completely secure display
system so that users can be sure that what they see on screen is what
they are supposed to see, and that no-one can eavesdrop on what''s being

FW: Echo Cancellation
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

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)?
