I was wondering about what effect different resolutions and sampling rates
might have on the effect as well. I tried downconverting Tom's sounds to
8-bit 11 KHz and didn't hear any difference (other than it sounding
lower-quality). I don't have audio software at work but was going to try
using lower-resolution sine waves as the input, rather than adjusting the
output after the fact, to see if that amplified the effect.
I have a feeling that while they're both important, the resolution might
play a larger role than the sampling rate. 65536 potential states for the
wave to be in at any given sample seems to me like it could lead to a lot
of inaccuracy when compared to a true sine wave.
