Hey everyone -- Sorry about the multiple postings, but I figured what the heck... I've just put on-line a whole lot of work I've done; papers, pieces, software, etc. Here's the link for the 2-3 people (beyond my immediate family) who might be interested: http://music.columbia.edu/~brad/ There's a fair amount of unix/linux work scattered throughout, including the big "My Music Book" thing I did a few years ago. Hope you enjoy this! brad

[linux-audio-dev] [ANN] Sonic Visualiser: An application for audio visualisation and analysis

by Chris Cannam

Announcing Sonic Visualiser, an application for viewing and analysing the contents of music audio files. http://www.sonicvisualiser.org/ Sonic Visualiser contains advanced waveform and spectrogram viewers, as well as editors for many sorts of audio annotations. Besides visualisation, it can make and play selections based on the locations of automatically detected features, seamlessly loop playback of single or multiple noncontiguous regions, synthesise annotations for playback, and slow down playback while retaining display synchronisation. Sonic Visualiser also introduces the Vamp plugin API, for plugins that extract descriptive or analytical data from audio. Vamp plugins for onset, pitch and note detection using the Aubio library are available, as well as plugins for tempo tracking, chromagram analysis, constant-Q spectrogram, spectral centroid, power curve and tonal change detection. There is also a comprehensive SDK for use by developers of Vamp plugins and hosts. Sonic Visualiser is Free Software distributed under the GNU General Public License. The 0.9 release is available now in source code form or as binaries for Linux, OS/X, and Windows. For more information and downloads, please see http://www.sonicvisualiser.org/ For more information about Vamp plugins, please see http://www.sonicvisualiser.org/vamp.html See also the SourceForge page for this project at http://www.sourceforge.net/projects/sv1/ Sonic Visualiser was developed at the Centre for Digital Music, Queen Mary, University of London and partially funded by the European Commission through the SIMAC project IST-FP6-507142.

Re: [linux-audio-dev] [ANN] realtime-lsm 0.8.6 available via SourceForge

For reference there are alternative ways to gain access to the rlimits functionality which don't rely on updated PAM (or login on PAM-less systems such as Slackware). Set_rlimits, available at http://www.physics.adelaide.edu.au/~jwoithe/set_rlimits-1.2.0.tgz is one alternative and has the advantage of operating on a per-user/per-application level rather than a per-user level (ie: elevated limits are set for users/groups running specified applications only). Yes, it's slightly less convenient but it works and is arguably more secure. Regards jonathan

[linux-audio-dev] [ANN] realtime-lsm 0.8.6 available via SourceForge

by Jack O'Quin

Download links (once SF finishes updating mirrors)... http://prdownloads.sourceforge.net/realtime-lsm/rt-lsm-0.8.6-kernel.patch.g… http://prdownloads.sourceforge.net/realtime-lsm/realtime-lsm-0.8.6.tar.gz?d… The Realtime Linux Security Module (LSM) is a loadable extension for Linux 2.6 kernels. It selectively grants realtime permissions to specific user groups or applications. This release provides the kernel patch formerly included in Andrew Morton's kernel development tree. This module is no longer available there, so I am releasing it for download via SourceForge. The kernel developers prefer their own rlimits solution for granting realtime privileges. Since that is their responsibility, I defer to their feelings. Since their solution requires PAM updates which have been very slow to appear in end-user distributions, I continue to provide this (simpler) solution via SourceForge for those who need it. There are no new features. You need not update, if an older version still works for you. This patch is not actively being developed, but I will continue to provide support as needed for the many users of distributions still lacking the required PAM updates for the rlimits solution preferred by the kernel developers. This release only supports kernel version 2.6.6 and newer. For older kernels, realtime-lsm-0.1.1 is still available. This LSM was written by Torben Hohn and Jack O'Quin, who make no warranty concerning the safety, security or even stability of your system when using it. But, if you do have problems, please report them on the linux-audio-user(a)music.columbia.edu mailing list -- joq

[linux-audio-dev] LV2 Logo again

by Thorsten Wilms

Hi! So LV2 will be the name by benevolent dictator descision :) More work on the logo: http://affenbande.org/~thorwil/wordpress/2006/05/19/lv2-5/ It's still a bit rough, so a few things might not be lined up perfectly, line width may be slightly inconsistent, but it should be good enough to get the idea and judge the overall shapes. I tried to bring in the idea of things connecting to build a whole. A puzzle in a way. I would like to hear of preferences (2 picks are better than 1), dislikes, and pointers to what could be improved with a specific variation. Cheers, Thorsten Wilms

[linux-audio-dev] Skype, ekiga, audacity, other audio util probs.

by Gene Heskett

Greetings everybody, this time I'm temporarily a Yupee, as in upstate michigan. I brought a laptop along, with linux on it, FC5, 386 version on an AMD64 turion in an HP dv5320us laptop.. The audio chipset in this is, from an lspci -v: 0:14.5 Multimedia audio controller: ATI Technologies Inc IXP SB400 AC'97 Audio Controller (rev 02) Subsystem: Hewlett-Packard Company Unknown device 30a4 Flags: bus master, 66MHz, slow devsel, latency 64, IRQ 11 Memory at c0003400 (32-bit, non-prefetchable) [size=256] Capabilities: [40] Message Signalled Interrupts: 64bit- Queue=0/0 Enable- The problem is that anything that requires it to handle a full duplex audio stream falls over very quickly. Skype in 10 seconds, ekiga even quicker, and in audacity, it will record great, and it will playback what it records great, but if you ask it to play as it records like one would do for overdubs and such, the sound in the headphones represents only that amount of the audio that may have hit the rails in the a-d, very chopped up, and often sounding like an echo thats cut into 2ms pieces and spread out over the next 30 seconds. Is there any known cure for this other than sueing HP for such a shitty piece of hardware that cost me about $1399 at CC? That of course will be a waste of time because their warranty shop says any and all warranties on it were null and void the instant I put a linux dvd in the drive. Any hints that result in getting something like skype or ekiga working will be applied with many profuse thanks offered. -- Cheers, Gene

Doesn't look that great and Steve and me would rather like to avoid any possible LV 2 vs LV II confusion. Should there ever be a LV 10, it should be LVX, though, because that's so cool ;) --- Thorsten Wilms

[linux-audio-dev] more questions on FST

by Aaron Krister Johnson

Hi all- I tried fst-1.7 under the latest version of wine on my Slackware 10.1 system--no luck still. I'm beginning to think that fst is not playing nice with glibc-2.3.4 Can someone who has used Kontakt under Linux share the output of /lib/libc.so.6 here with me so I can compare? Also, if glibc is indeed the problem, is there smething I can change in the fst code that would make it work with my current version if I can show debugging info--I prefer not to go through the headache of overhauling my entire system if there's a uick fix in fst code instead. Another question--barring that, if I do replace glibc, will I have to recompile my kernel, wine, etc? Best, Aaron.
