[speex-dev] echo suppression

There is experimental echo cancellation code.  Look in speex_echo.h 
and mdf.c.  Unfortunately there's no sample code, and I don't think 
anyone's had much luck getting the echo cancellation to work at all.  

Would anyone like to prove me wrong?  I'd love to see this work!  
I know it's really hard but just tonight the person I was talking 
to asked me, "Is there ever going to be a version of this program 
where we don't have to wear headphones?"  I told her, "I hope so, 
but we're lucky to have something as good as what we have now!" :)

Anyway, if you search the list archives you should be able to find 
some comments about how the echo functions are supposed to be used...

Good luck,
