[PD] Good filtering package

[Alexandre Torres Porres]

If you just want to see the freq/phase response, check [else/biplot], an
abstraction that plots biquad coefficients (also more than one biquad
filter in cascade). Use it with [else/bicoeff] that generates the
coefficients for many different filters - all of which are also present as
dedicated objects that also take signals to set frequency/resonance, like
else/bandpass~ (so you can use them and then bicoeff/biplot just for
visualization).

The biplot is actually an abstraction and you can build your own to plot
from difference equations/transfer functions. The ELSE library comes with a
tutorial that explains lots of computer music theory, including this filter
theory (see chapter 31). For reference, see
https://github.com/porres/pd-else/releases but you can also get it directly
from Pd (aka deken).

cheers
