Yes, I already was considering fiddling with that, but during the
cancellation process, the adapt_rate gets updated. I will comment
that part out for now. Maybe that's al I need...
The adapt_rate is initialized at 0.01, and is later changed
into..
Ahh... After 42 frames (in my case) the adaption is changed and
before that it is 0.
Anyway, will experiment with it. Thanks for the advice and the
echo canceller...
