Echo Canceller trouble in 1.2beta1

Just use SPEEX_ECHO_GET_SAMPLING_RATE to let the aec know what sampling
rate you're using (default is 8000).

There's no aggressiveness parameter, though...

Echo Canceller trouble in 1.2beta1
Terrific! The patch fixes my problem quite decisively.
I will want to use this with a 16K sample rate. Is it expected to work well with just another slight patch, or will we need to modify it more deeply?
Also, are there any tunable parameters besides tail length? I am wondering about the aggressiveness of adaptation and I know you are an expert in that area.
Thanks so much,
Michael
