Just for the record, can I mention that the split band audio clipper I
referred to isn't a simple compressor/clipper that generates lots of
harmonic distortion and splatter. By splitting the audio into sub-octave
bands you can clip each one, and then remove the harmonics, before
recombining so you end up with the same effect as rf clipping.
