I have found that in some cases a smaller/larger adaptation time
works<br>
better- it is nice to be able to set it at run time. Min noise
duration<br>
affects vad accuracy. Steve said it a bit more eloquently.<br><br>

What do you mean?</blockquote><br>
I do an isfinite check on the input samples- typically this never
happens, <br>
but i have gotten NaN data from the AEC. Not sure what caused it
though.<br>
Is this fixed already?<br><br>
