Speex dev - Jun 2005 - Speex 1.1.9 is out -- Try the new echo canceller

Hi everyone,

I've just released Speex 1.1.9. The main change in this release is the
echo canceller work sponsored by Tipic Inc (http://www.tipic.com/). It
is now possible to do acoustic echo cancellation and obtain good
attenuation after a short adaptation time. This has been tested at 8
kHz, but it should also work at 16 khz and above, so give it a try. 

There were also some fixes to the fixed-point, especially for the TI C5x
DSP family.

Enjoy!

	Jean-Marc

Hi.
I am trying out 1.1.9. What should be the value range for this
SPEEX_PREPROCESS_SET_AGC_LEVEL?? And the ideal value for a general default is?
Thanks!
