I looked in my list of pd-ext objects, but found no elliptic filters.
are
there any, or any way of getting their coefficients to use with
biquad~?
Elliptic filters are rather hard to design, most of the time you will
find
Butterworth or Chebyshev designs in our little audio world.
hey, joão
you still haven't made friends with fft? ;)
i've just finished a max external that does chebyshev filtering with a
variable number of poles and adjustable % of ripple in the passband.
repackaging this into a pd external wouldn't be too hard.
if you are interested in trying this out, drop me a mail and i'll see
when i can get it done.
volker.
ah ah, that's true. actually I didn't need anything so far that *had* to
be done with fft, so I never learned it properly (just unproperly a couple
of times, like yours, in which I didn't exercise afterwards).
of course I would be interested in the filter, as well as the rest of the
community should be. don't make any rush because of me, because it can
happen that after a while I don't need it anymore (in case you're too busy
with something else). but if you want to join your code to pd-ext,
everyone will be happy. (and windows compatible, please)
