[Csnd] Phase Filters implementation

Hi all,
Does any have, or know of, a Csound implementation of Max Mathews' Phase Filters? I'm trying learn about them, and would love to try using them. I'm aware of Diane Douglas' work in this area, but unfortunately I can't use her code because I'm a Linux user, and thus can't run the Max/MSP runtime or Max 4 Live, which are the platforms she has been developing for.
Thanks, Dave |

I have an implementation in csound somewhere but don't have it right now. The code follows directly the difference equation found here I believe: https://ccrma.stanford.edu/~jos/smac03maxjos/Oscillator_based_Complex_Number.html This is from the paper by Max Mathews and Julius Smith: https://ccrma.stanford.edu/~jos/smac03maxjos/ Its really just a resonator, and on its own has only minor differences from any other to use. Controlling the gain is a little tricky, they have a tendency to explode. Other than that I'm not sure they can be called 'phasor filters' without the control mechanism that Max wrapped around them.

Thanks, Joel. I have a copy of the paper, good to have the shorter page as well. My math skills are pretty primitive, so I have a difficult time trying to translate equations into sound code. I'm trying to get hold of a copy of the C program mentioned in the Mathews/Smith paper. - Dave On Thu, Mar 20, 2014 at 5:41 AM, Joel Ross <joel.binarybrain@gmail.com> wrote: I have an implementation in csound somewhere but don't have it right |
