Waveform Analysis?
by Ju'k J'unk 14 Apr '04

14 Apr '04

Hey Everyone, Would anyone know the approach to take to do an in-depth analysis of waveforms or waveforms of an entire audio track? I'd like to scan through the frequencies of a sample or mp3 (or other audio form). I want to come up with all of the recognizable patterns in a given sample. This way I can scan multiple tracks of a certain genre of music or sound and come up with the repetitions and patterns that make up what makes that particular piece of music simillar to others. I'll try to clarrify exactly what I'm trying to do better if you don't quite know what I mean.

polyphonic sampler under Pure Data
by julien.breval＠tremplin-utc.net 14 Apr '04

14 Apr '04

Hello I would like to program a polyphonic sampler/granular/wavetable machine (with some special options) If I understood well, the idea is to use [poly] to control as much copies of the audio~ subpatch as I want voices (Besides the 1.poly.synth.pd example, are there other examples showing how to use [poly] ? I know quite nothing about it) Also, isn't there a way to allocate multiple voices using only one audio subpatch, like [poly~] in Max/MSP ? Or maybe it's useless with Pure Data ? It doesn't bother me copying a subpatch 16 or 32 times, and connecting them to [poly], but what if I want 128 or 256 voices, for example ? or if I want to manage a dynamic number of audio voices in order to save CPU ? Any information about what deals with polyphony will be appreciated -- cheers, J --

Hi all, Is there any method of tallying values within a matrix? I.e. counting the number of times a 1 occurs, 2 occurs etc. Thanks Alyte

streamin~/out~ / jack.udp
by smoerk 14 Apr '04

is anyone working on a multi-channel streamin~/out~ external? the last postings in the mailing list if found are from November/December last year and there where some interest in extending streamio~ to multi-channel. if i were on linux, i would use jack.udp for this, but we are running a mixed setup with windows and linux machines. maybe a multi-channel streamio~ could use the same protocol as jack.udp? (unfortunately i don't have the skills to code it). jack.udp: http://www.alphalink.com.au/~rd/

envexp~ port
by roc 14 Apr '04

yo this may sound selfish, but i'm not a developer so i can't do it myself... for a long time i've been using and loving Trond Lossius' envexp~ external for max, a very nice Envelope with linear rise and exponential decay object. i'd love to use it with pd as well, but before i do so somebody has to port it. trond has all the source files in his site: http://www.bek.no/~lossius/download anybody up for it? i'm on os X besti r -------------------- %evol--------http://www.mego.at/evol.html %alku--------http://personal.ilimit.es/principio %imbécil----http://imbecil.net

pdp_ffmeg~ & mpeg4
by m 14 Apr '04

14 Apr '04

I found pdp_ffmpeg~ alonf with ffserver working great except for some "minor" issues: - pd segfaults when trying to feed a mpeg4 encoded stream to ffserver. mspeg4.. codecs are workin fine though. this happens with pidip-0.12.13 and all availble ffmpeg version I tried out and compiled against (0.4.8, latest cvs, 2003-03-04..) is this working for anyone? - mplayer plays everything, but it seem I cannot get anything out which make those lousy proprietary players happy.... anyone experienced with ffserver streaming and what players to recommend for playback? best, m.

Re: [PD] playlist

...it should be : playlist all 400 300 {Helvetica 10 bold} #457782 yellow black red without the \ ... cheers, sevy and that's the weird thing. i create [playlist all 200 300], save patch, close it and next time it is opened, instead of playlist i get rectangle saying : [playlist all 200 300 {Helvetica\ 10\ bold} #457782 yellow black red] if i try to erase }, pd freezes. but the help-playlist.pd from your tar.gz works allways. on debian, pd 0.37.0 devel. another machine, debian + pd pd-0.37-1 works fine. cheers Ales Zemene

elasticity algorithm
by siggmuss 14 Apr '04

14 Apr '04

Hi , is there any algorithm to make elasticity in pure-data? i send pure-data some elasticity effects made in lingo(director) to control sound parameters, like pannings ...and i was asking myself the way of doing it without lingo, just pure-data...... thanks in advance bye siggmus from fastmail -- http://www.fastmail.fm - Accessible with your email software or over the web
