[sdiy] Frequency multipliers

[Paul Perry]

just overamplifying - or otherwise making the sine wave squarer -
will give a mix of higher harmonics.
Making pure overtones (pure sines at 2x, 3x etc the original
frequency) isn't terribly interesting for audio, but I think there
is scope to do things with LFOs.
