In the few examples I looked at recently, the audio appeared to be clean and well-formed. Notching the two frequencies left very little. The system is using E1 TDM interfaces with aLaw encoding. I see there is a define called OLD_DSP_ROUTINES which causes conditional compilation in dsp.c, and is defined or not in the Makefile. Is it worth trying the old routines? What are the main differences between the old and the new?
