Dear Sir/Madam, I am PhD student in Speech Enhancement at INRIA in France. I am part of the Multispeech team, which is supervised by Emmanuel Vincent. My work includes echo cancellation, dereverberation and noise suppression. It's been 2 years I am using SpeexDSP for echo cancellation. I noticed there was a high-pass filter and I tried to deactivate it by commenting the lines related to SET_HIGHPASS_FILTER. Unfortunately, after I recompiled SpeexDSP, the high-pass filter was still on. Obviously, this procedure was wrong. Instead, I tried to set the variable"highpass_enabled" to zero. Again, it didn't set the high-pass filter off. Would you know what would be the right way to deactivate the high-pass filter ?
