[sdiy] Truly white noise

[harrybissell]

Guilty as charged... I used radio inter-station noise (FM) as a noise source to get

a 'waves' effect for a recording of a reading from Homer's (no... not Simpson)
Odyssey. The filters were the tone controls of the receiver, and the VCA was
the volume knob.  Worked well... hard to control.  The PAiA 2720 was a real step
up...
except for that fateful day when that receiver played "Lucky Man" by ELP....
