Ynzn's Interpolator 1.0
This is just a causal interpolator filter. You can set the
number of samples it takes to do the calculations between 1 and 250.
Some of you may wonder, why 250 and not another number? Well, the
dice decided it.
It picks num_samples samples, sums them up, and divides by the
number of samples taken. At high values it should give you the
"medium value" (this is a nasty translation from spanish: 'valor medio').
Actually it acts as a low pass filter. Higher values mean lower
cutoff frequencies.
Cutoff = 44100 / (N+1)
(B'cause the sampling freq is 44100 Hz)
Higher frequencies than the cutoff freq. are attenuated, but not
completely wiped out.
It comes with no demo or help because I thing it's not necessary.
It seems to work well with the PitchShifter and the Organ.
Bugs: By the moment it has never crashed in my computer (PII-350Mhz).
It should crash if there's no memory enough for its buffer,
but I couldn't reach this situation: A lot of other programs
crash before. A 250-float buffer is not so big.
