Videoconferencing with speex and jabber
Hi all,
<p>i have send a mail to the jabber mailing list and ask
them how to send speex data with the jabber instant
messaging protocol.
I have added the mail adter this one. If someone here
has any experience with jabber and speex please let me
know.
Thanks,

Re: Speex on Delphi
...eader by John Villar and
included the 1.0 release items and update the Delphi header to the 1.0
release along with building a DLL. If you would like these items, I would
be happy to send them to you. Other people were fairly helpful to me - so
its my turn to share. Just send an email to adrennan@wiredred.com and let
me know.
PS: not sure this will be in reply to the poster as I just joined the list -
so I apologize in the advance.

Videoconferencing with speex and jabber
Speaking of video conferencing in conjunction with Speex, we are
currently beta testing a solution we developed that offers multi-point,
multi-party video and audio using the Speex engine for voice.
http://www.wiredred.com/downloads/ecsetup.exe
The fair and good audio settings are Speex narrowband, high quality is
HawkVoice and toll quality is PCM.

Just curious, any reason you're not using Speex for high quality (at
18.2 and 24.6 kbps, I can't distinguish the coded from the original and

Noise problem with high harmonics
I just finished testing and integrating Speex into our test project. Speex
works excellent and sounds great for the bitrate.
I have noticed, however, on cheaper microphones that Speex will produce loud
static noise at high harmonics/amplitude in the sound. Is there some
setting to prevent this static? I don't have this problem with various
other manufacturer voice coders that I am using

Videoconferencing with speex and jabber
Hello Jean-Marc,
Regarding your question - a little background on the various choices,
Fair Quality is 15kbps Speex narrowband, Good Quality is 24kbps Speex
narrowband, High Quality is 32kbps ADPCM from HawkVoice and Toll Quality
is 64kbps PCM.
We also have 10 other codecs within the product including GSM, LPC and
others that we currently do not expose.
To us, quality is a combination of

Server based audio merge
I tend to disagree. It normal human conversation it wouldn't make much
sense to have 2 people talking over each other at the same time. Thus,
it most scenarios you would have only one talker anyway. Additionally,
encode->decode/mix/encode->decode isn't a very efficient CPU process for
a server, it's complicated to keep timing correct and it has a negative
impact on total

reommended settings for low bitrate voicecom codec ?
Without seeing some examples of your Speex implementation, it would be
difficult to comment. I can tell you that you need to make that the
conversion between floating point and fixed is done properly. This seems to
be a common problem.
Also, I am confident that TeamSpeak is using LHACM.ACM and distributing it.
While HawkVoice is being distributed, it doesn't appear to be used at all.

reommended settings for low bitrate voicecom codec ?
Hello,
HawkVoice doesn't have a 6.3kbps codec for CELP, it has a 4.5kbps CELP codec
and I do not believe it is being used by TeamSpeak. The 6.4kbps CELP being
used in TeamSpeak, to which you are referring I believe comes from Lernout &
Hauspie's LHACM.ACM file which it appears you are redistributing (I assume
TeamSpeak has a license and permission to do this). The only people I

It doesn't have to be done that way. You can simply have the server
echo the voice streams

Speex settings and jitter
In my experience most of the jitter related issues are because people are
using too small of audio buffer sizes that match the framing size of Speex -
particularly in Windows. This isn't a problem with Speex, but as a
programmer you should collect and append a few frames to match the size of
your output audio frame buffer before attempting to play the sound.
