...How does speex AGC preprocessor will perform on this type of audio recording? Maybe I am wrong and AGC is not really what I need to equalize the two persons in my phone conversation? As I Understand, AGC will perform better if each party is recorded in a different channel? Thank you, Yanick Bourbeau

I usually implement this kind of feature outside of speex becauses I want a better control on how it happens and when to do something about it :) Yanick Bourbeau On 11-08-29 04:16 PM, Clifton Craig wrote: > +1 on this question as I wanted to start playing with it as well. > > On Aug 29, 2011, at 9:41 AM, Shridhar, Vasant wrote: > >> I have been trying to understand how to get the VAD algorithm >> working.

I have been trying to understand how to get the VAD algorithm working. I sent an input stream of all zeros into the preprocessor but still got a return value of 1 indicating that speech was detected. Is this feature not available with the latest release? I thought at the very least it would detect this as silence and return 0 but that does not seem to be the case. Does anyone have any
