Re: [PD] dub chords in Pd
every reggae music mix since Lee Perry has been using this type of sound. I used a cheapo yamaha portasound in the early 80s to do that, plus a fat phasor effect on it. then there's a short delay on it as well with a different EQ setting. if you want to create a phasor effect in pd you either create a very short delay or (I think better) a bank of notch filters, either boost or cut. with a metro you can then slide through the frequencies with range and speed of your liking.

Re: [PD] dub chords in Pd
Agreed, Check the help patch H15.phaser.pd and H03.band-pass.pd, I'd start with running your favorite saw chords into a bandpass filter triggered by note-on, sweep that downward. Patch that into the recirculating delay Andy described (touch of distortion with a bandpass in the delay feedback loop). Finally, add a phasor to the final output. For maximum dub, dangerously vary all important parameters. In sum you have three components: 1. Simple instrument with bandpass filter descending (and resetting) on note-on 2. Recirculating delay with slight distortion on the input, and a bandpass filter in the feedback loop 3. Phasor on output You could probably do similar any number of different ways, but this is how I'd try it.

Of course I would expect the corners of the vowel to depend on individual characteristics, but I dont know where to start. Anyone any ideas? Greetings, Ludwig I'd like to know as well... about two years ago, I made a patch to play Wikipedia's vowel samples according to three criteria (two [vradio] and one [tgl]) : 01234 6 [i][y][ɨ][ʉ][ɯ][u] 5 [ɪ][ʏ] [ʊ] 4 [e][ø] [o] 3 [ə] 2 [ɛ][œ] [ʌ][ɔ] 1 [æ] [ɐ] 0 [a][ɶ] [ɑ][ɒ] And then some more. Personally I'm mostly interested in [iyɪʏeøeœaœəuʊøʌɑ] (the nonnasals used in my own speech), but I'd like a language-independent locator too. Then for example I numbered the above like 001 = 6 0 1 = [ɶ] 200 = 4 0 0 = [ɛ] 511 = 1 1 1 = [ʏ] 531 = 5 3 1 = [ʊ] The digits are : row number, column number, subcolumn number. I'd add a fourth number that'd toggle nasals (because I need [ɛ̃̃œ̃ø̃ɑ̃ɔ̃õ] to reproduce my speech) and perhaps a fifth number that would toggle [ː] but it might be more appropriate to write them as a pair of identical vowels (especially as some of them mutate to diphtongs in my speech). I haven't looked much in the analysis part of it yet. I thought I could analyse the sound samples, extract their cepstrums, cross-fade them, resynthesise using a different envelope and tone... but I haven't tried any of that at all in the end (well, maybe I started trying it and it didn't work...). ___ | Mathieu Bouchard -- Villeray, Montréal, QC___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] IPA Vowel space analyzer
I had a go a number of years ago at coding an LPC-based formant detector for PD, based on the Speech Filing System from University College London. It has since remained on my to do list, since I got the object to load but there were problems in getting it working (i.e. it didn't, and crashed PD). In theory, if you can detect the peaks in a Linear Predictive Coding-derive polynomial plot, then you can determine the vowel very accurately. It would be nice to make this work - I'll dig it out and perhaps someone can help me understand why it doesn't work (and fix it). I'll dig it out and try to GDB it tonight, but I have to feed my child now. Best, Ed Metastudio 4 for Pure Data - coming soon!

Re: [PD] Pd-list Digest, Vol 67, Issue 106
IOhannes, Thanks for the input. What is strange is that the 'Media' tab in the Menu doesn't list any soundcard atall (not like it did on my former Ubuntu system). Also, I tried invoking Pd with the -alsa tag, but Pd told me that there is no such tag :( Still (not) working... David Dear all, I switched operating systems to Fedora 13 yesterday and it is great, except that I cannot get Pd to address ALSA. The build goes well, no errors, and Pd is there and it looks fine, except when I go to 'Audio settings' the boxes next to input and output are empty. There are no options to select. I have installed every ALSA package that I can find, and still no joy. Any ideas? This is a sample what the console reports during configuration: per default, Pd uses OSS. you have to manually tell it to use ALSA. Menu-Media-ALSA or start Pd with -alsa. then the audio-menu should list your soundcards (that is: if you have any; can other (alsa) applications play sound?) checking tcl.h usability... yes checking tcl.h presence... yes checking for tcl.h... yes checking for main in -ltcl85... no checking for main in -ltcl8.5... yes checking for main in -ltk85... no checking for main in -ltk8.5... yes alsa= yes I find the '' before alsa to be troubling.

Re: [PD] dub chords in Pd
i recall one simple way to create that effect was to use a delay as send effect and then route its output to one channel of the mixer where you could then apply the send effect, creating a loop. the delay then could go on almost forever, and be manipulated using the eq of the channel. i spent quite some time (and dope) with this back then ;-) ff Am 28.10.2010 um 12:02 schrieb Roman Haefeli: On Thu, 2010-10-28 at 10:16 +0100, Marco Donnarumma wrote: Yes, check this: http://soundcloud.com/bemong/03-rhythm-sound-mango-drive well, the whole tune, specially at 3' 05 so those are the dub chords I'm talking about :P Sorry for not specifying before, I _love_ RhythmSound. His tracks are mastered in way that really deserves the term mastering. There is very much in it which makes the chords sound dubby. Many combinations of effect chains are competing with each other.
