WORKSHOP 1: REAL-TIME SYNTHESIS AND AUDIO PROCESSING USING PD Miller Puckette, University of California at San Diego, USA Sunday, October 31, 1:00 PM - 3:30 PM USD 40 / EUR 32,50 Pure Data (Pd), available for Mac, Windows, and linux, offers real-time audio processing and synthesis, a Max-like GUI, and a very high degree of integration between control, audio, video, and I/O operations, in an extremely light package. This workshop, intended for people familiar with software synthesis but not assuming any particular technological background, will show what Pd is like and how to get started with it. Time permitting, the more shown. Miller Puckette was the top scorer in the 1979-1980 William Lowell Putnam Mathematics competition and was awarded Putnam and NSF fellowships to study mathematics at MIT and Harvard, where he finished his Ph.D. in 1986 under Andrew Gleason. From 1979 through 1986 Puckette also studied computer music with Barry Vercoe at the MIT Media Lab. He then joined IRCAM in Paris, where he wrote the Max graphic programming language, which has become the lingua franca of live computer music. In 1994 Puckette joined UCSD where he is now professor of music and associate director of the Center for Research in Computing and the Arts. Puckette's research interests include human-machine interaction strategies and real-time audio and video processing. http://www.icmc2004.org/

[linux-audio-user] [ANN] swh-plugins 0.4.11

by Steve Harris

There is a new release of my plugin collection. Bugfixes: (I've lost the attributions, appologies to the fixers!) reverse delay - denormal fix flanger - stability problem multiband EQ - problem running multiple instances in one host Sorry, I didn't manage to get through the TODO list. New plugins: artifical latency plugin - mainly useful for testing crossfader - not really tested, may work There is a new build system (libtool based) that should make it easier to port to other platforms, but may cause problems. Enjoy, Steve

Re: RE: [linux-audio-user] Muse Score compiled from source has

by ico＠fuse.net

Things are getting more interesting. Apparently drakfont shows that the font mscore20 has been successfully installed, although in the preview pane it looks like any other ordinary font (is this normal)? In addition, I found that the drakfont installed the font in the following directory: /usr/X11R6/lib/X11/fonts/drakfont/ttf/ fonts.dir describes the font as follows: mscore20.ttf -misc-mscore20-medium-r-normal--0-0-0-0-p-0-iso10646-1 Could someone please do me a favor and cross-compare this with their setup? Finally, should I install the font first and then recompile the app or should this have no bearing on the issue? Your help in this matter is greatly appreciated! Best wishes, Ico

[linux-audio-user] sndpeek: real-time 3D FFT + audio visualizatoin

by Ge Wang

Dear All, We at the Princeton SoundLab have released our light-weight (stupidly simple yet useful) real-time 3d waveform audio and FFT waterfall visualization. GPL. Plug in a mic, and have some fun, or run it on a file. http://soundlab.cs.princeton.edu/software/sndpeek/ features: - real-time visualization of waveform + waterfall plot - supports scaling - supports rather ridiculous 3d rotation and transformation - centroid, rms, rolloff plot - mic input and file input - full framerate graphics - need OpenGL/GLUT There is now a mailing for the vis apps we are releasing. This has served us well. It is great for teaching, and also for playing around - even during live coding performances. For example, see http://on-the-fly.cs.princeton.edu/listen/ This is part of a suite of real-time visualization tools that will be released soon. We are of course open to comments and complaints. Best, Ge!

[linux-audio-user] ALSA and SPDIF for via82xx - alt: choice of SPDIF cards

by Brad Fuller

Hi, I have been trying to get a via82xx on a DFI mobo to output SPDIF. (The reason: the analog audio on the right side is noisy.) Anyway, I have had no luck. I brought the SPDIF pins out but I see no clock when checking with other hardware. If I could get this working it would mean I won't need to search for another card. If anyone has experience with getting SPDIF working on a via82xx I'd appreciate any help. I've visited http://alsa.opensrc.org/index.php?page=via8233 and related links but no help so far. ----- Besides that: Can anyone recommend a card where SPDIF is a breeze to set up? ;-) I have a Cardeluxe (which works great in Win2k) and a Delta-66 in other machines. I haven't revisited the drivers to see if Delta-66 SPDIF drivers are working yet. However, I don't want to spend too much $$$ on this new card (It's for mythtv). Any recommendations for a SPDIF card is much appreciated! thanks! brad

Thank you Gerard. I deleted the -werror flag in the makefile.config and now pdp compiles. thanks again, rob

[linux-audio-user] rec creates empty files, play plays nothing

by millward

I've tried this for Red Hat 7.3, Slackware 9 and Slackware 10, but so far, no luck. I'm trying to create a WAV file with my guitar. First, I set the software mixer for line-in and line-in gain, and for PCM and master volume for playback and active everything on the mixer I can, just out of desperation. I then use the command line in a terminal window: rec -V -r44100 -c2 -s -w new_file.wav Is this command OK or did I goof? My sound card is a Creative Sound Blaster Live 5.1. I'm using line-in which is a blue plug on the sound card. I've tried various methods to input sound, such as: guitar->adapter plug->sound card line-in guitar->Eurorack UB802 mixer->adapter plug->sound card line-in guitar->Eurorack UB802 mixer->amplifier->adapter plug->sound card line-in guitar->amplifier->adapter plug->sound card line-in I can hear my guitar input through my computer speakers so I know the signal is going into the card and coming out of it. In all cases the WAV file is created with no error messages. I then try to play it back using: play -V new_file.wav In all cases, there is silence. Nothing at all and no error messages. I've tried all kinds of variations on the rec command and have set the volume higher, lower, whatever. So far, nothing. I must be doing something really dumb, but I don't know what. Can anyone tell me how to create a WAV file using rec and get it to play? A couple years ago I did get good results using rec and play, but I've lost the notes I made and can't remember how. I'm not happy with myself for that. Any information would be very welcome!

[linux-audio-user] Muse Score compiled from source has corrupt score fonts

by Ivica Ico Bukvic

Hi all, The title says it all, I guess. The application Muse Score looks incredibly promising yet I fail to understand why are the fonts looking all corrupt (most of them being blocky squares, straight vertical lines or simply non-existent). No errors were reported during install, no configure problems, the app starts cleanly (there is a warning regarding inability to figure out locale but other than that no errors). After logging out and restarting the X server the appearance of the corrupted fonts changed but they were still trashed. I am using mdk 10 (albeit heavily updated). Any help at this point would be greatly appreciated (in part because this would be one of the apps I would want to teach and/or demo in my class, provided that it works on my machine, of course :-). Best wishes, Ivica Ico Bukvic, composer & multimedia sculptor http://meowing.ccm.uc.edu/~ico/ --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).
