audio output AND input with the Rpi?
by Chris Jack 31 Oct '13

31 Oct '13

Hey folks, Apologies as this post is not strictly about Pd, though Pd will be a crucial part of my final setup so whatever solution I find ought to work with Pd. Also, there is a chance the issue might lie with Pd. I just don't know. I'm looking for a usb bus-powered audio interface for the Rpi that can take a stereo input and provide stereo output *at the same time.* * * I have tried a couple different images and a couple different audio interfaces, to no avail. Perhaps there's something can be done with one of these setups to get it working? First, the Pd-LA custom Raspian (v1) image and Pd 43.2: ..with Behringer UCA202 (at 44100khz): Alsamixer picks the device up but the input section shows nothing. Pd (gui) audio preferences allows selection of the interface for both input and output. Output only is lovely and clean but as soon as the device is selected for audio input the audio quality drops horrendously (vaguely recognisable from the original signal).. ..although what gives me hope is I CAN software monitor the input (poorly) in 'Test Audio and MIDI' with this arrangement. ..with Behringer UCA202 (at 48000khz): Output only in Pd is poor (beating and popping sound - possibly sounds like a samp rate conversion issue). When device is selected as Pd input software monitoring is possible and oddly, though the result is still poor, there is effectively no drop in quality from having the device selected only for output and the monitored signal sounds drastically better than at 44100khz. ..with Turtle Beach Amigo II* (at 44100): Alsamixer shows both input and output and allows to change gain of both. If plugged in from boot and only the output is selected in Pd it works but with a lot of jitter. Selecting the device for input too causes a further drop in audio quality although again I can software monitor the input in 'Test Audio and MIDI' If plugged in after boot the OS crashes. The Satellite CCRMA (operating via ssh) and Pd-extended: ..with Behringer UCA202 (at 44100 and 48000): Alsamixer picks the device up but again the input section shows nothing. If I have the device plugged in from boot then I get the same behaviour with it as I do in Pd vanilla on the Pd-LA Raspian image, ie. software input monitoring but at an extremely poor quality. If I don't plug the device in from boot I see it in Pd audio prefs but get this: ALSA input error (snd_pcm_open): No such file or directory ALSA output error (snd_pcm_open): No such file or directory from the Pd terminal and this ALSA lib pcm_hw.c:1401:(_snd_pcm_hw_open) Invalid value for card ALSA lib pcm_hw.c:1401:(_snd_pcm_hw_open) Invalid value for card oops: ALSA cards not reported in order? from the ssh terminal. ..with Turtle Beach Amigo II* (at 44100khz): Alsamixer shows both input and output and allows to change gain of both. If plugged in from boot and then only output selected in Pd I get clean audio out. If I try to select the Turtle Beach as audio inout in Pd then Pd stalls indefinitely when I try to 'Test Audio and MIDI' or make anything in a patch. Same direct input monitoring by default. Also get ALSA input error (snd_pcm_open): Device or resource busy ALSA output error (snd_pcm_open): Device or resource busy from the Pd terminal if I don't have it plugged in from boot, though no message in ssh terminal. *It also appears that by default the Turtle Beach does direct input monitoring of some sorts, the output stage sending out a clean copy of whatever signal is going into the input stage whenever the device is plugged into a usb port. With the Pd-LA image this occurred simultaneously while input monitoring in Pd. I guess this is part of the design of the Turtle Beach, though their documentation is devoid of any useful info regards this. If this is the case then this ain't the sound card for me, though clearly some might find this a very useful feature. Just to give a bit more info about what I'm attempting: I wish to run the stereo input from the Turtle Beach through Pd, play with the audio signal using data from an accelerometer (not nearly there yet) and then send the audio out through the Turtle Beach's stereo output. Apologies for the essay. Hopefully my findings are useful for others and hopefully I can get my rig working! Help muchly appreciated. I've probably left out some crucial bit of info so please shout me if I have! Cheers, Chris Jack.

tabread2~ noisy output
by peiman khosravi 30 Oct '13

30 Oct '13

Attached is a simple patch that reads sound file data from an array with tabread4~. Does someone know why the result is so noisy? Please try with this sound file (96k 24bit): https://dl.dropboxusercontent.com/u/47945259/test.aif. It sounds like some sort of extreme quantisation noise. But maybe I've missed something in the patch. I'm on the latest version of pd vanilla on os x 10.7.5.

pd on Mac OSX 10.9
by Dan Wilcox 30 Oct '13

30 Oct '13

Howdy all, I updated to OSX 10.9 "Mavericks" last night and pd-extended runs fine. Only note is that a dialog box pops up when you first run it saying "You need X11 installed to run pd." In that case, simply download and install XQuartz which provides X11: http://xquartz.macosforge.org/landing/ I had XQuartz installed before but the OS upgrade must have removed it. In any case the dialog they give you includes some extra info so beginners should be able to figure it out. -------- Dan Wilcox @danomatika danomatika.com robotcowboy.com

by Joe Deken 30 Oct '13

30 Oct '13

New Blankets Inc. is a non-profit Foundation dedicated to the the re-invention of the Free Community Public Library in the realms of new media. Specifically New Blankets develops the dimensions _of_ -- free/open communities -- _circulation_ and _sharing_ mechanisms -- technology innovations which together weave and support new benevolent cultural communities. New Blankets is pleased to announce today the recognition of Jonathan Wilkes as our latest "Artist in Transit" Fellow. . New Blankets has provided Jonathan with an initial honorarium of $500 to support his work. . In addition to the initial honorarium support, New Blankets has also launched a "1 : 1 matching mini-fundraiser" during the coming month (October 14 - November 14, 2013), to further support Jonathan and the Artist-in-Transit Fellowship: 1) That is, any contributions to New Blankets during Oct 14 - Nov 14 which you kindly care to make and designate for "Artist in Transit" will be matched 1 for 1 by New Blankets -- up to a $500 matching limit. 2) At the end of the one month mini-fundraiser, the total sum (your contributions + NB matching amount) will be presented to Jonathan at *PdWeekend* -- to be held Nov 15-17, 2013 with Miller Puckette & Friends in San Diego and Los Angeles CA. *********************************************************** If you would like to make a contribution -- small or large -- to the New Blankets Artist-in-Transit fundraiser, please send e-mail ASAP to New Blankets, using the special fundraiser address : "wilkes_ait(a)newblankets.org" When we hear from you, we will arrange a convenient way for you to send your check or electronic payment to New Blankets, by whichever of several available methods may be most convenient for you.) *********************************************************** ** PdWeekend** If you would like to participate in PdWeekend with us in California on Nov 15-17, you are cordially invited and most welcome! Kindly RSVP "yes" and let us know your plans to participate with us in San Diego (Nov 15) or Los Angeles (Nov 16-17) by sending e-mail ASAP to: pdweekend(a)newblankets.org We will then send you a confirming e-mail immediately, and we will keep you advised as our *PdWeekend* plans and the details of events move forward, from now until November 15. The *PdWeekend* events are quite informal, but they also will include four structured workshops on Saturday Nov 16 -- in co-operation with CrashSpace LA: .... .... .... .... .... .... .... .... .... .... .... * Miller Puckette: Pd+Raspberry Pi * Katja Vetter: DIY Live Sampling Microphone-Build & Slice//Jockey * Ico Bukvic: Laptop Orchestrating with your Friends * Jonathan Wilkes: Your Computer, Your Creativity ** Registration is required each of the above workshops ** .... .... .... .... .... .... .... .... .... .... .... You may wish to peruse our (very much in-progress) plans for *PdWeekend* and the stellar list of participants -- including Miller, Jonathan the other workshop presenters above -- at: http://newblankets.org/nov15.html ** Join us in CA in November! Invite your friends, too! **

Mac: 64 bits faster than 32
by Miller Puckette 29 Oct '13

29 Oct '13

Just FYI. I just heard back from Rand Steiger who tried out a big patch in both the 32 and 64 bit versions of Pd on Macintosh - 64 bits came out substantially faster. So if you've got a 64 bit machine, I think you're going to want the 64 bit Pd, unless you have old externs that can't load into it. cheers Miller

[PD-announce] earGram: concatenate sound synthesis/generative music
by Gilberto Bernardes 29 Oct '13

29 Oct '13

Hi, I’m working on a project for my PhD that recombines audio segments according to pre-defined generative methods. For those familiarised with concatenative sound synthesis, earGram reformulates the notion of unit selection algorithms to encompass generative music strategies. It relies heavily on timbreID a known library for PD by William Brent. So, here's the website that hosts the project: https://sites.google.com/site/eargram/ You can find project examples in the download section as well. P In addition there are plenty of abstractions that may interest you, in particular clustering and dimensionality reduction algorithms... As you can guess, I would like to get feedbacks and advises. Best, Gilberto Bernardes _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

[PD-announce] Radium 1.9.31 released for Linux
by Kjetil Matheussen 29 Oct '13

29 Oct '13

Radium 1.9.31 is a big release with many new features and bug fixes. 1.9.31 is the first release with Pd embedded. Pd embedded in Radium has got approximately the same features as Max for Ableton Live. (https://www.ableton.com/en/live/max-for-live/) Screenshot: http://folk.uio.no/ksvalast/radiumpd.png Video 1: http://folk.uio.no/ksvalast/radium_pd.ogv Video 2: http://folk.uio.no/ksvalast/radium-pd-invertnote.ogv A windows version will be released later. Radium homepage: http://users.notam02.no/~kjetism/radium/ Most important changes 1.9.30 -> 1.9.31: * New demo song: BlowFish! Made by www.magnetophon.nl * Save hashmap elements in sorted order so that songs can more easily be compared textually * Menu entry to show name of all included pd externals * Help menu options to edit keybindings and menues * Song comment dialog * Fix "Switch Window Configuration" menu option * Removed "Error. y2>=window->height: ..." error. Just print to stderr instead. * Removed the "Something strange just happened in the function Blt_markVisible" warning (print to stderr instead) * Option to set number of scrolls per second. Scrolling too often can be tiresome for the eyes. * Make it easier to connect objects and see connections in the mixer, plus adjust object sizes * Patchbay sound object * Fix crash loading Soundfonts in the Fluidsynth and Sampler instrument * Show stars around filename if theres unsaved data * When quitting or loading, only ask sure/yes/no if edited since last save. * Change "Set Patch For Track" to "Set Instrument For Track" in the instruments menu. The word "patch" should not be exposed to the user anymore. * Be able to load files with DOS char set * Changed internal radium block size to 64 (similar to Pd) * Sending note events between sound objects (green lines) * Enable undo for on/off effect controllers * Pd extended is included as a sound object. 921 externals are included. GUI is working. Several instances is working. Can be used to write both audio effects and note effects. * Fix qt paths on Archlinux (Javafant/archlinux) * Many minor bug fixes _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce
