Ok I see how to do most of it. As your posted suggestion for inband dtmf detection points out, looking at mp3_writer.c wav_writer.c I can see the audio is in a 16 bit array that is written out in either case. My question is the basic one. If you have port->buf[0] for example is that the frequency of the audio at that point. In short how do I relate audio sample data to frequency? I also notice wav_writer.cpp and mp3_writer.c have put_frame functions that include a callback call if the function pointer if set. Is there any reason not to do this also in conference.c? Yea the put_frame in conference.c does not have such a feature.
