Max/MSP Raw Filter Pack

I’ve ported a collection of raw filters to Max/MSP from puredata.  These are basic single pole and zero components, for real and complex signals, with their coefficients controllable by audio signals. They allow the construction of more complex filters.

There is an example of a 5-pole butterworth lowpass provided in the pack.

They are currently compiled for OS X only, but the source is provided and should compile fine under Windows.

For the theory about their use, turn to Miller Puckette’s execellent (and free online) book, Theory and Techniques of Electronic Music, Chapter 8.

They are available on my software page, under a BSD license (unlike most other content on this site which is cc licensed).
