BadCable is a v2 AudioUnit which attempts to simulate a bad audio cable. The result is a form of waveform distortion. With some settings, the effect sounds like an FM broadcast when you're at the edge of reception (check out preset #2 "FM Edge").
The effect is rather dependent upon the average level of the incoming signal, so the Intensity parameter is designed with a very wide range to cover all possibilities, including very soft 24-bit signals.
Very high settings of Intensity will sound like a "cable" that is so "bad" is doesn't work at all :-)
