[speex-dev] More Speex (pre-processing) Options

So I have had a chance to delve deeper into the new pre-processing
code- I was also able to get VAD, AGC, Denoising, etc working inside of the
current release candidate (1.0.3). For some reason, the 1.1.2
release didn't properly encode/decode in our system (on windows)
and I haven't had time to determine why. In any case, all of the features
jointly work very well- great job!
I realize the echo cancellation element may still be in development, but I am
having trouble getting that part of the preprocessor to work. When
I don't pass NULL into the speex_preprocess for the echo parameter, things
seem to go haywire- some memory appears to be getting trampled somewhere
(this is probably my fault). Maybe I am misunderstanding the purpose of this
parameter? Except for the first few packets, the preprocessor
appears to be removing all audio- The algorithm I am using passes in a recently
decoded frame... Any ideas? Do I need to set some settings in somewhere
in order for this to work properly?
