"This is designed for "less is more"
and comes with a pair of filters, pair of shelves
and two mid-freq bells. This isn't "quite" cookbook
stuff. Have fun trying to match them with a stock EQ.
Tech-wise these use a fitting method
to approximate analog response, improving the
high-freq shape significantly (whether you compare
to cookbook or Orfanidis-style compensation). To
further improve the very-high frequency response
there's 2x oversampling (actually that's mostly so
the high-shelf cutoff can go to 24kHz and the
low-pass to 28kHz, but it also looks a bit better in
a spectrum analyzer).
Processing is done with my SVF-inspired
filter structure which is cheap to calculate while
handling low-frequencies rather better than the
average direct form filter (proper 0df SVF would be
even better, but would roughly double the CPU.. I
tried, but figured it's not really worth it). "
