[ANN] International Conference on Spatial Audio, Nov 10-13 2011, in Detmold, Germany

by Jörn Nettingsmeier

hi *! sorry for the slightly off-topic post, but since spatial audio has been a frequent topic lately, i think some people here might be interested. linux or FLOSS won't be exactly in the limelight, but yours truly will make sure there are at least 2-3 boxes with your favourite OS and audio tools humming along in various places. oh, and you might come early and watch a few high-end mixing consoles boot - the startup screen will bring tears to your eyes (as will the price tag, unfortunately :) unfortunately, there will have to be an admission fee, which we haven't decided on yet. but we're trying to keep it reasonable. don't shout at me when it turns out to be a bit more costly than LAC, though... jörn *.* ICSA 2011 - International Conference on Spatial Audio November 10 - 13, Hochschule für Musik, Detmold Organizers: Verband Deutscher Tonmeister (VDT), in cooperation with Deutsche Gesellschaft für Akustik e.V. (DEGA), and European Acoustics Association (EAA). Contact/Chair: Prof. Dr.-Ing. Malte Kob Erich-Thienhaus-Institut Neustadt 22, 52756 Detmold Mail: icsa2011attonmeister.de Phone: +49-(0)5231-975-644 Fax: +49-(0)5231-975-689 Summary: The International Conference on Spatial Audio 2011 takes place from November 10 to 13 at Detmold University of Music. This expert‘s summit will examine current systems for multichannel audio reproduction and complementing recording techniques, and discuss their respective strengths and weaknesses. Wavefield synthesis systems, a higher-order Ambisonics array, as well as 5.1/7.1 installations in diverse acoustic environments will be available for comparative listening tests during the conference. Structured plenary talks, paper and poster sessions will revisit fundamentals and present latest research. A series of workshops will be dedicated to practical implementations of spatial sound capture and playback methods, and their esthetic and psychoacoustical implications for music perception. Concerts that include music specially arranged for the conference will let you experience various spatial sound systems in "live" conditions. Call for papers and music: Your contributions are welcome, either as presentations, posters, or workshops. Submissions will undergo a review process, and accepted contributions will be published in the conference proceedings. The conference language is English. We are planning structured sessions on the following topics: * Multichannel stereo * Wave field synthesis * Higher-order Ambisonics / spherical acoustics * 3D systems * Binaural techniques An additional session will be dedicated to related miscellaneous contributions, such as hybrid systems and perception/evaluation of spatial music reproduction.

Re: [LAU] LinuxSampler problem (notes disappearing)

by Julien Claassen

Hi! Oh dear, I definitely didn't have as many voices and stream configured. I think in my best times I had 128 voices and 90 disk streams, which was always fine for me. Even with the big piano, also the sampletekk Black Grand.

LinuxSampler problem (notes disappearing)

by Julien Claassen

Hello Everyone! I recently started having problems with my Linuxsampler. I've seen that ones before at a friend's place, but never had it myself. I'm currently running LinuxSampler 1.0.0.cvs10. Especially when I load a big piano and use the sustain pedal, after a while notes keep disappearing. I may hit them and hit them again and then they will play. Even if I lift up on the pedal, the problem keeps persisting. I have to completely reload the instrument, which is a bugger, since it takes ages. And that way LS isn't useable anymore in recordings. It's not reliable. Does anyone have an idea, why that is, if I may change something in my setup to prevent that? Or is there a fix already? Kindest regards Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net the Linux TextBased Studio guide ======= AND MY PERSONAL PAGES AT: ======= http://www.juliencoder.de

yoshimi 0.060.9

by cal

0.060.9 corrects an error on my part that resulted in a licensing anomaly. Thanks to Adam Huffman for bringing it to light. There's now yoshimi 0.060.9 in git (0.060 branch) and a tarball on sourceforge, <https://sourceforge.net/projects/yoshimi/files/> cheers, Cal -------------------- yoshimi-0.060.9 licence anomaly corrected. yoshimi-0.060.8 Nothing too adventurous, just an incremental advance on 0.058.1 adding Paul's Unison and Reverb enhancements, jack session support, panning inversion corrections and assorted other tweaks and bug fixes.

list all flac files by bit depth?

by Aaron L.

How would one go about listing all flac files that have a bit depth of greater than 16? Since this info is stored in an id3 tag I can't seem to figure out how to go about this. Thanks for any input. -Aaron

real-time wave to midi?

by Dan Muresan

Probably a tall order, but if I have a non-MIDI keyboard, is there any software that analyzes the audio and generates MIDI? For monophonic noise at least? :) -- Dan

Music Made WIth Linux: The Infinite Repeat - The Speeding Train

by Jeremy Jongepier

Dear all, My entry for the KVR One Synth Challenge 26 (http://sites.google.com/site/kvrosc/osc-26-zynaddsubfx): *The Infinite Repeat - The Speeding Train* http://linux.autostatic.com/images/2011-04/the_infinite_repeat-the_speeding… As the One Synth Challenge rules dictate, all the instruments, sounds and noises are generated by ZynAddSubFX. Well, almost, because as Linux users we have some more choice than on other platforms. So I used 11 ZynAddSubFX-DSSI plug-ins in Qtractor together with 3 separate Yoshimi instances for the voice patches that use the PADsynth engine (apparently the DSSI plug-in can't handle those patches). I used seq24 to trigger everything and Qtractor for mixing and a bit of mastering. Some external effects were allowed, given they are freely available and don't alter the original sound (so no phasers, choruses etc.). For this track I used Calf gates, Calf EQ, SWH SC3 sidechain compressor, AMB panner, Calf Vintage Delay, Freeverb reverb, Invada Stereo compressor and a fast lookahead limiter. Voice patches I used: - SuperSaw (Paul Nasca) - Extreme (Will J. Godfrey) - Bass 2 (Paul Nasca) - Eeooww (Will J. Godfrey) - Drumkit (Paul Nasca, tweaked and layered, the snare sound consists of 4 or 5 different snare sounds) - Snare 1 (M?sterious) - Soft Kick (AutoStatic) - 8 Bit Car (M?sterious) - Soft Ahh (Will J. Godfrey) - Wind and Surf (Will J. Godfrey) - Binary Piano 2 (Paul Nasca) The track was composed and sequenced on the train when commuting to and from my work. Hence the title. Best, Jeremy

UA25 noise problem w. nVidia chipset

by Dave Phillips

Greetings, I've been working with Ardour3 on my laptop, a machine with an AMD Turion X2 CPU and an nVidia 8200M integrated video chipset. Recently I started monitoring my test recordings through the headphone output of my UA25 and I notice that when I move the mouse it creates scratchy sounds, though QJackCtl reports no xruns and my recordings are unaffected. I verified the problem with Ardour2 and Mixbus. It doesn't occur when I use the integrate audio chipset (snd-hda-intel, wahoo). Running 'cat /proc/interrupts' reports that usb1/usb3 share interrupt 17 and usb2/usb4 share interrupt 16. I've tried switching ports around but that didn't get rid of the noise. Any further suggestions ? Best, dp
