There are two variables: how many samples to be corrected (which affects
computation) and table length (which affects memory requirements).
For BLEP, you can achieve decent sounding aliasing reduction with less than 32

My advice is this: don't get too caught up in the theory! I tend to do that
myself, so... Just implement something quick and dirty and *listen* to the
results.
Also, I really don't think the choice of window matters very much. You
could probably get away with Hamming. And 150 samples at 44k1 is pr

For BLIT, these sub-sample delayed grains are usually integrated to get a
saw/square/pwm signal.

Hello Everyone,
I'm looking for a reality check on practical implementation aspects of
the minBLEP "corrective grain" approach. I'm trying to compare the
computation cost to other methods, but I'm having difficulty working out
the correct grain parameters to make a valid comparison.
Assuming
