Bill,

Thought about the zero-crosings. Does it actually make sense to change 
the phase reversal time? Since the samplerate is drifting anyway, there 
will be a small time difference between a phase shift and there 
zero-crossing. Also -if the samplerate would be exactly 24 kS/s-, the 
time when the phase shift occurrs can be somewhere, i.e. wouldn't be 
sync'ed to the zero-crossing. Right?
So it may be easier (also for the receiving side) to let it remain at 
0.1 seconds.
Comments welcome.
