|Description:||attached is a preliminary patch enabling UWB (Ultra wide band 32kHz)|
part of the Speex codec. warning! it is not complete and the sampling
rate is currently hardcoded to 32 kHz. the patch works fine with
the app_mp3.c backend streaming mp3/http to speex/32000.

Have you tested this with meetme? will meetme require a patch to operate @ 32khz (rather then 8)?

This is going to take some extra work to get happy, that's for sure :)

alfredh, are you alive? can we get some more information here?

I have not tested with meetme, only app_mp3.c
it might work, as long as all participants are using Speex/32000 Hz
my first goal is to get the Asterisk mp3 player working with Speex
hardcoded to 32 kHz, including stereo (conf+SDP), and then hopefully
add some better logic for handling any sampling rates..

How is this patch coming? What sip/iax client supports speex @ 32khz
By: Alfred E. Heggestad (alfredh) 2005-07-17 17:23:23
new patch uploaded, re-diffed against CVS HEAD and made much
simpler (smaller). still hardcoded to 32kHz though.
there are AFAIK no SIP/IAX clients supporting Speex 32 kHz,
this is what I am doing at the moment..

This is very interesting work, but it can not be even cosidered for inclusion without a disclaimer with digium, and without the hardcoded 32k changes. I am going to suspend this bug for now, please re-open when you are ready to disclaim, and have resolved the hardcoding issue.
