[Speex-dev] Echo cancellation Question?

[JonganKS]

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?
