Hi,
I use speex 1.1.12 in my program, but I found a strange thing about Echo
canceller. That is, I'll hear an explosion in a certain frequency inputing.
And I use the echo canceller in 44100Hz sample rate, disable AGC and Denoise.
Can you tell me what's wrong with me?

Yes, First, I'd use _ctl() to modify the setting of sample rate, and Second, I tried using 8kHz sample rate to compare and the resonance and explosion does not appear. I found because of notch_radius will sharp the sound and let the resonance not to be produced. The frequency around the pitch G3 Freq.196Hz.
