"audio I/O stuck... closing audio" error message
by Yu Lao 24 Aug '09

24 Aug '09

I'm trying to run Pd on a Linux distribution based on Debian (AVLinux). My audio hardware (RME) has ALSA drivers and seems to work but I'm unable to test it - there is no sound from any application, selecting ALSA or Jack doesn't improve the situation.. Jack runs fine, I can see Pd and the system, connect them and everything looks good except that in the instant that I select Jack as audio device for Pd the canvas displays this error message. Googling sends me to the source code and mail archives that are not accessible from here (China), so I'm clueless. I'd very much appreciate any suggestions how to solve the problem. Even how to test audio hardware with a test signal or so. Best Jurgen

Gem and ffmpeg
by Miha Tomšič 24 Aug '09

24 Aug '09

Hello! I am trying to compile ffmpeg into Gem on Linux (fedora 10 and 11). Which version of ffmpeg is Gem 0.91-3 compatible with? I tried various 0.4.9 and 0.5 (finally an official version of ffmpeg), but function declarations are not compatible. Thanks and take care, M.

patch to profile filters - sugestions?
by João Pais 24 Aug '09

24 Aug '09

Hi, just dia a couple of patches to get the profile of filters by testing them - linear + log versions. I had some questions to see if anyone is interested in this: - is this resolution good enough, or do you think that more is better? this one is already good enough to get an idea - I think it works precisely, but what's your opinion? - I might do later one patch with both linear and logarythmic versions, but was too much work for now - it works a bit slow, but it was as good as it got with the standard settings of env~. I might try out later to see if with other settings it runs faster. - what do you think about the logarythmic one, is the scale ok? maybe there's a better formula for this - to get the rms power of a freq doesn't work in the log version, because I couldn't find out how to connect frequency values and table indexes. you're welcome to patch it, if you want. Btw, anyone has good links/references to filter theory courses/papers? Hope this is useful, JoÃ£o Pais -- Friedenstr. 58 10249 Berlin (Deutschland) Tel +49 30 42020091 | Mob +49 162 6843570 Studio +49 30 69509190 jmmmpais(a)googlemail.com | skype: jmmmpjmmmp

Efficient additive Synthesis
by Andrew Faraday 23 Aug '09

23 Aug '09

Dear All I've just recently found a more efficient method of additive synthesis. It might be covering old ground, of course. Anyway, I've enclosed a demo patch. Comments and suggestions on efficient synthesis are welcome.

PD font size issue on Gentoo
by Jarra 22 Aug '09

22 Aug '09

Hi, I installed Pd on Gentoo, and the GUI text looks good, but the console text and the text in the PD objects is rather large, popping out of the object boxes. (as you can see here -> http://2009.jarra.nl/pd_20090822.png) Is there a way to change this? The Tk, Tcl and Pd version I have currently installed are these: gentoo:~$ eix dev-lang/tk [D] dev-lang/tk Available versions: 8.4.15-r1 8.4.18 8.4.18-r1 ~8.4.19-r1 ~8.5.7 {debug threads truetype} Installed versions: 8.5.7(10:54:03 08/22/09)(truetype -debug -threads) Homepage: http://www.tcl.tk/ Description: Tk Widget Set gentoo:~$ eix dev-lang/tcl [D] dev-lang/tcl Available versions: 8.4.15 8.4.18 ~8.4.19 ~8.5.7 {debug threads} Installed versions: 8.5.7(10:52:33 08/22/09)(-debug -threads) Homepage: http://www.tcl.tk/ Description: Tool Command Language gentoo:~$ eix pd-extended [I] media-sound/pd-extended [1] Available versions: (~)0.40-r1 (~)0.40-r2 (~)0.40-r3 {adaptive bassemu boids bsaylor creb cxc cyclone deprecated earplug ekext ext13 flashserver flatspace flib freeverb ggee hardware hcs iem_ambi iem_bin_ambi iemgui iemlib jack jasch_lib loaders mapping markex maxlib mjlib moocow moonlib motex mrpeach msd oscx pan pdcontainer pddp pdogg pmpd sigpack smlib tof toxy unauthorized vbap windowing zexy} Installed versions: 0.40-r3(15:29:49 08/22/09)(adaptive bassemu boids bsaylor creb cxc cyclone earplug ekext ext13 flashserver flatspace flib freeverb ggee hardware hcs iem_ambi iem_bin_ambi iemgui iemlib jack jasch_lib loaders mapping markex maxlib mjlib moocow moonlib motex mrpeach msd pan pdcontainer pddp pdogg pmpd sigpack smlib tof toxy unauthorized vbap windowing -deprecated -oscx -zexy) Homepage: http://www.puredata.org/ Description: Realtime multimedia environment plus a collection of plugins [1] "pd-overlay" /usr/local/portage/layman/pd-overlay Thanks for any help, Jarra

They install into the same dir, so you can't. You can always reinstall 'puredata' later.

Efficient additive synthesis
by Andrew Faraday 22 Aug '09

22 Aug '09

Hey guys This might be covering old ground but I've been looking at more processor-efficient methods of producing additive synthesis. And I've attached a patch with what I've come up with. It's a personal epiphany to me, working out that it can all be run from a single phasor~ Any comments and suggestions for efficient synthesis would be welcome.
