It seems to me that a peak voltage detector combined an average (or better 
RMS) voltage detector would be suitable for sensing compression. If the peak 
to average ratio is low, mute the audio. Properly setting the integrator 
time (low pass filter) for the average detector would be tricky.

Take care,
