I guess it's kind of 1-Bit PCM sampled using the CoCo's "Zero Crossing
Detector" (cassette port). Recording is done saving the (loop-) times
between "bit changes" of the cassette port. Playback is done outputting
the "bit changes" to the CoCo's "One Bit Sound" and waiting the recorded
(loop-) times again (kind of sequencer). Steve must have been an expert
of this stuff, remember his great "Spectrum Audio Analizer" Pak...
