In this 12-minute video, I give you a tour of some advanced Max filtering tools and filter design options that go above and beyond the biquad~ object. With the filterdesign, filterdetail and plot~ objects, you can take filtering to the next level.
my "next level" would be to calculate the new filter types myself uign messages (or in best case even signal based).
if anyone would be bored enough to build it for me that would be great.
i have lowpass, highpass, bandpass and shelving filter coefficient patches (mostly copied from zack settel i think) and it would be so lovely to have the brickwall filters (and eventualy the butterworth, but it is not too important for now) as max patch, too.
I tried playing around with this, and I got some crazy feedback. Just gave myself a heart attack by switching between filter modes, and nearly blew out my speakers. Perhaps it's best not to be changing the attributes of filterdesign while the audio engine is running, but seriously a little warning would have been nice.
Otherwise, really interesting tutorial, and definitely did inspire me to try it myself!
