For example, in zynaddsubfx, we count the ascending

multiplied with the signal. Counting zero crossings prevents clicking on
lower notes, and it makes higher notes more punchy. That algorithm works
very well for a buffersize of 256 samples (at 44100 samples/s), but it fails
at 32 samples (since the zero crossings of 32 samples are often not
representive).
That could be a good method, but why should this (or anything a synth
does) depend on period size ? Implementation may be a bit simpler if
it does, but that's poor excuse (IMHO :-)...
