[sdiy] samplers & pitch shifting

"'I believe the LM-1 sounded better because I didn't incorporate strict
textbook digital sampling theory. By the book, I should have filtered
out any playback frequencies above the Nyquist frequency, which is a
little less that one-half of the sampling frequency. I used a sampling
rate of around 27kHz. However, filtering on playback would have made
some of the drums sound pretty dull. Instead, I let some of the
frequencies above that point get through, because the results - which
can get distorted - sounded like the sizzle of drums anyway. Thanks to
that decision, the LM-1 sounded better than some drum machines with the
same sampling rate, because it had the highs. In a sense, I'm thankful
that I wasn't very good at the engineering.'"
