SPEEX_PREPROCESS_SET_AGC_LEVEL
...om 1 to 32768, with the default being 8000.
I've been using 70% of the maximum in my application. You should
probably experiment to see what works best for you.

Memory leak in denoiser + a few questions
...loced in line 167). It's in Speex 1.1.4
by the way.
I'm trying to make the denoiser work with my application and has got
reasonable noise reduction after applying the denoiser. I, however, haven't
been able to find any information of what the purpose of
SPEEX_PREPROCESS_SET_AGC and SPEEX_PREPROCESS_SET_AGC_LEVEL is?
Kind regards

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

Patch to make SPEEX_PREPROCESS_GET_AGC_GAIN use dB, and _SET_AGC_LEVEL use a int32
...we get
a fixed point AGC.
Best regards,
