help with making a parametric EQ
by hard off 07 May '08

07 May '08

from this site, in the section titled 'group delay' http://www.dspguru.com/info/terms/filtterm/index2.htm i got an equation to calculate the 'group delay' of a linear FIR filter. the equation is: group delay = phase shift / -2pi where phase shift is a value of radians / hz can anyone please tell me how to calculate the phase shift with a basic FIR filter in pd? i'm hoping that if i can get that, then i can add/subtract the filtered signal to a slightly delayed original signal to make a reasonable parametric EQ. (oh, and sorry if this mail gets sent to the list twice - i forgot to add the [pd] bit to the subject first time)

Re: [PD] chromatic fft

Dear Mirko Maier I don't have really a solution for you question but maybe something that can help you. For some time I have been developing a brunch abstraction for the spatialization spectral feedback delay techniques, and I used Data Structures to make a final representation in 2 and 3D of the bins in the room. Even if it's not what you asked it can be already a start for you work. Anyway what I have done is simply a visualization of the bins and doesn't allow any control. Not all the patches has this room simulation check these files: 4-channels: fft.pan4~-help.pd and fftEQ.pan4~-help.pd 4-channels-round: fft.round~-help.pd and fftEQ.round~-help.pd Also to implement a chromatic color scale in data structure is really hard to I came up with a simpler ideia. You can find them here: http://bernardes7.googlepages.com/software All the best, Gilberto http://bernardes7.googlepages.com _________________________________________________________________ Receba GRÁTIS as mensagens do Messenger no seu celular quando você estiver offline.

I know that question is ask and discussed ever and ever again, but from time to time there is a need of an update caused by the newer hardware offerings on the market. What kind of GC would be a recommandation to buy. Thank you in advance Markus Brandt

Re: [PD] end of the vline~

> I feel this is a head-slappingly stupid question, but is there any way > to tell when vline~ has finished its run? It doesn't seem to me a stupid question at all - also I've heard that stupid questions don't exist. I don't think there's any "direct" way - i.e. any way to have vline itself tell you when he's finished. However you can certainly achieve what you need. I can think of 2 approaches: 1) Analize the same messages you're feeding into vline to drive a [delay] 2) Analize the same messages you're feeding into vline to set up a [threshold~] and manage its output bangs One or the other may result the simpler depending on the context (i.e. assumptions and restrictions about the messages that can come to vline in your particular case). -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

Re: [PD] any tips on fart synthesis?
by Ed Kelly 06 May '08

Sawtooth modulation (~5-20hz) of the cutoff frequency of a resonant lowpass filter (such as vcf~) and a simple pitch curve (rise fall, fall rise, fall fall, rise rise) on a complex waveform going through the filter. 4-point amplitude envelope - fastish attack, slightly slower decay with an imbalance of maybe 3-6dB between the second and third points. Medium resonance. Then you stick the whole lot through another filter - a peak EQ. Some kind of envelope. Maybe something needs to be done with the pitch, in sync with the saw tooth modulation?

I got similar sounds also from recordings in a wash basin using empty plastic bottles or hands, or mouth sounds (like trumpet blowing, but under water). or really try to rebuilt it synthetically, probably two amplitude modulated waveshaped signals. would be nice to see synthetic solutions for it. marius.

pd extended on Ubuntu Hardy Heron
by francois labastie 05 May '08

05 May '08

Hello! Does someone knows how to install puredata extended on Ubuntu Hardy Heron? I tried Pd-0.39.3-extended-debian-testing-i386.deb, from http://puredata.info/downloads, and I got "Error: Dependency is not satisfiable: libflac7" I tried Pd-0.39.3-extended-rc5-debian-stable-i386.deb, from http://at.or.at/hans/pd/installers-0.39.3-extended-rc5.html, and I got "Error: Dependency is not satisfiable: libflac7" as well. I used to work with it on Gutsy, but now with Hardy Heron how can I do? Thanks a lot for your help. FranÃ§ois

Re: [PD] ossmixer of ext13 not working with pd-extended
by Ingo Scherzinger 05 May '08

Hello Frank, Thank you for the info! I downloaded "amixer" but didn't succeed in compiling it. It could be "amixer" or it could be me (I'm relatively new to Linux and don't really know what to do when there are errors while compiling). I'll keep trying! Maybe I'll get it to work somehow.

I am looking for english translations of Mario Costa's writings. JStor has Technology,Artistic Production, and the 'Aesthetics of Communication' but I have not found a good anthology or other collections that include more from Costa. Does anyone have any suggestions? Please respond off list. Thanks Greg gregpond(a)gmail.com
