[speex-dev] Complexity vs BitRate

Jean-Marc and others,
We are using Speex inside our Video Conferencing application and have some
questions about the trade-off of complexity vs bitrate. A little background
information is needed:
1. For us the actual bit-rate isn't that big a deal. Speex running at
14kbps or 8 kbps is minor compared to the video traffic running at 128, 256
or 384 kbps.
2. We care a little about CPU usage - The lower usage the better.
3. We are using 8khz 16bit mono for the raw audio
4. A peaky data-rate isn't a big deal.
We currently use the following options: DTX, VBR (impling VAD), ENH and ABR
Our goal is to get the best sounding audio as possible. Does VBR make more
sense than ABR given our requirments?
When I set a bit-rate on VBR is that the max that the VBR will go to in a
given second or how exactly does that work
<p>P.S. - Who do I have to flog at Xiph to not have the mail archives show
real email addresses.
