But quick looks may be deceiving ... You have been deceived, the filter has the tanh()s inside the recursive loops, so it's not a linear filter. I'm deceived too easily. ;) To make up for my mistake, I did a quick port of Victor's CSound code to a Pd external here: http://footils.org/pkg/moogladder-0.1.tgz It's just a quick copy-and-paste version, not really tested, so expect bugs and be careful with the volume! The makefile only has a pd_linux target, but it may be a start if someone wants to take over. Possible enhancements could include signal inlets for frequency and resonance instead of float inlets and maybe table lookup for the tanh-calculation instead of direct computation.

[PD] Csound opcode Moogladder to Pd?
Frank - that was fast! Thanks! I haven't had time to try it out yet but will report back when I get home. The csound opcode I've used myself is a modification of the original with signal input for cutoff (please find it attached). Signal input for both cutoff and resonance would of course be awesome. If anyone could compile a windows binary of this I would be very grateful. I use both winxp and ubuntu. /Anton ml_aak-csound.csd Description: Binary data ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] Csound opcode Moogladder to Pd?
Hi, I once made some kind of implementation of the Moogladder filter to Pd. I never evaluated the implementation so I'm not sure if it really sounds as the Csound version or gives the same output as in the paper. It is kind of crude Pd code anyway. =) But I'll attach the patch here if you wan to give it a try? -Mika Message: 2 Date: Mon, 25 Aug 2008 22:49:11 +0200 From: Anton H?rnquist [EMAIL PROTECTED] Subject: [PD] Csound opcode Moogladder to Pd? To: pd-list@iem.at Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=ISO-8859-1 I've used the Csound opcode Moogladder (based on an algorithm by Antti Huovilainen) in Pd using csoundapi~. It uses a lot of cpu cycles but it sounds really good. The csoundapi~ external is useful but it only allows one instance per patch on windows so ideally I would like to have this opcode as a Pd abstraction or external and get rid of the csoundapi~ external. Is it possible to convert the Moogladder opcode to a Pd abstraction?

The csound opcode I've used myself is a modification of the original with signal input for cutoff (please find it attached). Signal input for both cutoff and resonance would of course be awesome. I now made a version where cutoff and resonance are signals. This version is a bit more CPU intensive now, as some computations had to move into the DSP loop to react to the changes in center frequency. I played a bit with a rational tanh approximation from the music-dsp list but it didn't sound good anymore. If someone wants to play with other approximations e.g. table lookup: Just change the function mytanh. The filter response gets nasty and loud if the center frequency is near or above the sampling rate. Maybe it should be restricted as well. But then, resonance at 1 will make everyone jump, too...

Re: [PD] find formants from fft table
Hi Ricardo, i have written an external (sms_peaks~) that does exactly what you want. It is part of my naive but usable pd-based implementation of sms. It analyzes only half the signal vector as it is designed to work in combination with rfft~. Please see the help file. You can find it in my svn at https://svn.g.org/ext/trunk/ sms_peaks/ .
