Icecast - May 2005 - Are there any success stories streaming to an icecast2 server using Asterisk or OpenMCU?

I have read more about asterisk and have succeeded in using it's app_ices 
function and a sample conference .  I would like to learn more about lowering 
the latency between the Speaker on the SIPphone->Meetme 
Conference->ICES->Listener stream. 

Thank you

Vorbis is always going to have some latency, but you could try the 
following:

* Disable the burst options in Icecast

* Lower the listener's buffer size to the smallest possible value

* I think there's a setting in Ices which you could also reduce

any format is going to have some latency. Vorbis is no different in this
regard.

These 2 are related, so both have to be done to reduce the latency.

ices already flushes audio out every second. In 2.0.1 you can state in
<encode>

   <flush-samples>11025</flush-samples>

to change the default (which is samplerate). icecast 2.2 also rebuilds
vorbis only streams, but that isn't changeable from the half-second
flush currently.  Most of the lag is in the icecast->listener buffering
