I should've seen this coming, even more so when I used audio-related
stuff a few times. Well, I'll work on it and try to add to both
differentiators and filters, but I can already smell the burn on the
CPU.

In the meantime, except for the "default" weighting for
differentiators, did the new script behave well enough?
