On the website you will find up-to-date instructions, as well as important information about deadlines, travel, lodging, and so on. Read on for more details! We invite submissions of papers addressing all areas of audio processing based on Linux and open source software. Papers can focus on technical, artistic or scientific issues and can target developers or users. We are also looking for music that has been produced or composed entirely or mostly using Linux and other Open Source music software. The Deadline for all submissions is January 11th, 2012 The Linux Audio Conference (LAC) is an international conference that brings together musicians, sound artists, software developers and researchers, working with Linux as an open, stable, professional platform for audio and media research and music production. LAC includes paper sessions, workshops, and a diverse program of electronic music. The upcoming 2012 conference will be hosted at CCRMA, Stanford University, on April 12-15. The Center for Computer Research in Music and Acoustics (CCRMA) at Stanford University is a multi-disciplinary facility where composers and researchers work together using computer-based technology both as an artistic medium and as a research tool. CCRMA has been using and developing Linux as an audio platform since 1997. http://ccrma.stanford.edu Stanford University is located in the heart of Silicon Valley, about one hour south of San Francisco, California. This is the first time LAC will take place in the United States. http://www.stanford.edu We look forward to seeing you at Stanford in April! Sincerely, The LAC 2012 Organizing Team

[LAD] Some mudita24 fixes in SVN now.

by Tim E. Real

Hello. I noticed mudita24 SVN was in a sad state, crashing the whole system. There were already significant changes and improvements since release 1.0.3 So I fixed 'er up. Please give it a spin so we can put out a release sometime. mudita24 is the updated replacement of envy24control, the gui for ice1712-based audio hardware. http://code.google.com/p/mudita24/ subversion: svn checkout http://mudita24.googlecode.com/svn/trunk/mudita24 mudita24-svn 1) Moved to cmake build system. No more autotools :) (The default install location is /usr/local. It can be changed - try the handy 'ccmake' gui). 2) Fixed wrong alsactl location. Now cmake looks for alsactl. Override with environment variable ALSACTL_PROG. 3) Added usage info. 4) Fixed serious fatal X error: height too big. Was far too many markings, brought down the system, due to lowest alsa db value now returning -9999999. Installed some limits. 5) Executable is now called mudita24 instead of envy24control. This should help kind packagers out there finally get this into the repos. Cheers. Tim.

[LAD] AV Linux

by Jens M Andreasen

Here is a distro that does away with most of what (some old people in Korea as well as) quite a few users on this list dislikes about "modern" Linux desktop: http://www.bandshed.net/index.html I am using it now, it is current and works like a charm :) .. I really think it deserves to be mentioned on the official LAD pages somewhere /j

[LAD] LV2 and Naspro - MCP Plugins

by Aurélien Leblond

Hi everyone, I was wondering something about the Naspro LV2 Plugins: Are they considered as a workaround until we get the DSSI and LADSPA plugins ported to LV2, or more of a "definitive" solution? The reason why I'm asking the question is that I'm currently porting the AlsaModularSynth internal modules into LV2 plugins for Ingen. And when I'm creating synthesizers in AMS, I'm often (if not always) using the LADSPA MCP plugins created by Fons Adriaensen. So would there be any point porting these MCP plugins to LV2 as well, or would the general consensus be "what's the point, we have Naspro for that". Thanks in advance! Aurélien

[LAD] [OT] RIP Dennis Ritchie

by Lorenzo Sutton

It seems Dennis Ritchie [1] passed away last week end. He was the inventor of the C programming language and core developer of UNIX. I guess we are all relying in some way or another on this man's research and inventions in our 'contemporary computer lives'. Lorenzo. [1] http://en.wikipedia.org/wiki/Dennis_Ritchie

[LAD] Client connection to JACK fails with socket error -- help?

by Simon Kalteis

Hello all! My name is Simon, I am a long-time user of JACK on Debian-based Linux systems. I prefer to compile JACK myself so I always set the JACK-packages in Debian to "hold", remove everything from /usr and put my build into /usr/local. Starting with Debian 6.0 "squeeze" (Kernel is 2.6.38-1-686 #1 SMP), this seems to cause problems somewhere. I checked out jackdmp from SVN yesterday, build was ok. jackdmp starts up, QJackCtl is able to connect and the connection graph shows up. But any other client I want to use with JACK causes the following error: [snip] Cannot connect to server socket err = No such file or directory Cannot connect to server socket jack server is not running or cannot be started [/snip] My test client of choice is mplayer. (SVN r3418) I checked whether the runtime linker uses the correct libs: /usr/local/bin/mplayer libjack.so.0 => /usr/local/lib/libjack.so.0 (0xb718a000) This should be ok. The list of file descriptors for the running jack server is [snip] jackd 13063 simon cwd DIR 8,6 36864 146594 /home/simon jackd 13063 simon rtd DIR 8,6 4096 2 / jackd 13063 simon txt REG 8,6 22899 223189 /usr/local/bin/jackd jackd 13063 simon mem REG 8,6 145629 236929 /usr/local/lib/jack/jack_alsa.so jackd 13063 simon mem REG 0,16 82493164 2070826 /dev/shm/jack-1000-0 jackd 13063 simon mem REG 8,6 1153328 391304 /usr/lib/libasound.so.2.0.0 jackd 13063 simon DEL REG 0,16 2995543 /dev/shm/jack-1000-2 jackd 13063 simon DEL REG 0,16 2995541 /dev/shm/sem.hTRyxy jackd 13063 simon DEL REG 0,16 2070960 /dev/shm/sem.2Jamky jackd 13063 simon mem CHR 116,5 241895 /dev/snd/pcmC0D0p jackd 13063 simon mem CHR 116,6 241896 /dev/snd/pcmC0D0c jackd 13063 simon mem REG 8,6 1323460 246009 /lib/i686/cmov/libc-2.11.2.so jackd 13063 simon mem REG 8,6 116600 228035 /lib/libgcc_s.so.1 jackd 13063 simon mem REG 8,6 149392 245993 /lib/i686/cmov/libm-2.11.2.so jackd 13063 simon mem REG 8,6 30684 245999 /lib/i686/cmov/librt-2.11.2.so jackd 13063 simon mem REG 8,6 9736 246001 /lib/i686/cmov/libdl-2.11.2.so jackd 13063 simon mem REG 8,6 117367 245998 /lib/i686/cmov/libpthread-2.11.2.so jackd 13063 simon mem REG 8,6 958479 223178 /usr/local/lib/libjackserver.so.0.1.0 jackd 13063 simon mem REG 8,6 975012 214075 /usr/lib/libstdc++.so.6.0.13 jackd 13063 simon DEL REG 0,16 2070886 /dev/shm/sem.5FWprn jackd 13063 simon mem REG 0,16 1012 2070831 /dev/shm/jack-1000-1 jackd 13063 simon mem REG 0,16 70712 1906270 /dev/shm/jack-shm-registry jackd 13063 simon mem REG 8,6 113964 228057 /lib/ld-2.11.2.so jackd 13063 simon 0r FIFO 0,8 0t0 2070809 pipe jackd 13063 simon 1w FIFO 0,8 0t0 1906224 pipe jackd 13063 simon 2w FIFO 0,8 0t0 1906224 pipe jackd 13063 simon 3u CHR 116,7 0t0 241899 /dev/snd/controlC0 jackd 13063 simon 4u unix 0xece16900 0t0 2070957 /dev/shm/jack_(default)_1000_0 jackd 13063 simon 5u CHR 116,5 0t0 241895 /dev/snd/pcmC0D0p jackd 13063 simon 6u CHR 116,6 0t0 241896 /dev/snd/pcmC0D0c jackd 13063 simon 7u unix 0xece166c0 0t0 2070959 socket jackd 13063 simon 8u CHR 116,1 0t0 2555 /dev/snd/seq jackd 13063 simon 9u unix 0xece16000 0t0 2070962 /dev/shm/jack_(default)_1000_0 jackd 13063 simon 10u unix 0xf4c71200 0t0 2995537 /dev/shm/jack_(default)_1000_0 jackd 13063 simon 11r FIFO 0,8 0t0 1906200 pipe jackd 13063 simon 12w FIFO 0,8 0t0 1906200 pipe jackd 13063 simon 13u unix 0xf4f81440 0t0 2995542 socket jackd 13063 simon 17r FIFO 0,8 0t0 1906224 pipe jackd 13063 simon 18w FIFO 0,8 0t0 1906224 pipe [/snip] So the server apparently has sockets open -- question is why are clients except QJackCtl unable to connect to them? I am out of ideas. I basically recompiled everything from source a few times (including alsa-lib, libsndfile, jack, mplayer) and nothing changed. I appreciate any help on this problem. Thank you very much in advance! Simon --

[LAD] LV2 AMS Plugins (0.0.2)

by Aurélien Leblond

Hi Guys Just posted on Sourceforge a new version of these plugins. I added: - a CV to Hz convertor and Hz to CV (seems to be working ok, the VCO is now in tune) - The VCA module from AMS (called VCA Lin and VCA Exp) - The ENV module from AMS With those, it should be possible to create very simple modular synths in Ingen. >From the few test I have done, things seems to be working fine, but feel free to provide any comments and feedbacks! The file can be downloaded from here: http://sourceforge.net/projects/avwlv2/files/ Aurélien
