by Kjetil S. Matheussen

Download from http://ccrma.stanford.edu/~kjetil/src/ Snd-ls v0.9.5.4 ================ Contains -------- Snd v7.15 from 17.8.2005 About ----- Snd-ls is a distribution of the sound editor Snd. Its target is people that don't know scheme very well, and don't want to spend too much time configuring Snd. It can also serve as a quick introduction to Snd and how it can be set up. Changes 0.9.5.3 -> 0.9.5.4 -------------------------- -Changed default resampling quality to SRC_SINC_BEST_QUALITY -Added workaround for shift-handling across various keyboard settings. (shortcuts for zoom in and undo works with american keyboards now.) -Added check for Guile 1.8. Snd-ls crashes with guile 1.8. (all versions I have tried of 1.7 seems to work though...) -Use JackPortIsPhysical instead of "alsa_pcm" when finding jack ports. -Updated the rt stuff to latest versions. *************************************** *************************************** Das_Watchdog V0.2.1 =================== About ----- Das_Watchdog is a general watchdog for the linux operating system that should be runned in the background at all times to ensure a realtime process won't hang the machine. Changes 0.2.0->0.2.1 -------------------- *Cleaned up source a bit. *Properly find number of timer processes. *Added shortcuts for optargs.

[linux-audio-announce] Call for help for LinuxTag2006

by Arnold Krille

Hi all, as every year the famous german LinuxTag is taking place. This year in Wiesbaden from 3. to 6. May. Yes, this is just one week after LAC2006, which has several advantages and disadvantages: + It is a good chance to come to Germany for LAC, have one or two days of holiday and then join the LA-Group at LinuxTag! + Maybe even repeat your LAC-Talk at LinuxTag? (see www.linuxtag.org for details on the Call-for-Papers but be aware that it ends January 15...) + Wiesbaden is more in the center of germany so perhaps some LA-folks from the north of germany can join us? - The new place for LinuxTag together with LAC being a week before enforce two of the main-booth-members of the last years (Christoph Eckert and Frank Neumann) to be only a visitor at LinuxTag or even less... That leaves a hole in the organisational part. :-( So here is my call: I am willing to do some work organizing a booth and a group of staff but I need YOUR help! If you are a german LA[DU]-member and have some spare time, join in! A booth at LinuxTag is a good opportunity to present Linux Audio to the people, not only to developers but more to users. The crowd is mostly industry (producers, technicians, musicians) at the weekdays and home-recording-users at the weekend. Don't be afraid, there won't be much questions about setting up drivers for consumer-cards (and If there are, we usually send them to their distributions booth :-) ). But there will be a lot people thinking about using your app in studio! So you definitly don't want to miss this chance! If I get positive answers from at least two other people by weekend, I will apply for a booth and things start rolling, so don't hesitate, check your calendar, plan for another week of holiday and join me (us?). So long and thanks for all the fish, Arnold -- visit http://dillenburg.dyndns.org/~arnold/ --- Wenn man mit Raubkopien Bands wie Brosis oder Britney Spears wirklich verhindern könnte, würde ich mir noch heute einen Stapel Brenner und einen Sack Rohlinge kaufen.

[linux-audio-announce] Mic-In-Room Simulator

by davidrclark＠earthlink.net

Greetings to all, Announcing grad_Boxster for creating impulse response functions (IR's) for rectangular parallelepipeds --- for example concert halls modelled as giant boxes --- but using the *gradient* of the solution field projected on a direction specified by the user, similar to the operation of a pressure-gradient microphone --- in a room. At the URL below is a link to this package for downloading as well as a NON-optimized, alternating demo of grad_Boxster versus Boxster (i.e. "ordinary stereo versus binaural" or even "speakers versus headphones"): http://home.earthlink.net/~davidrclark grad2_Boxster is also available for simulating second-order mics in rooms. Extending grad_Boxster, the gradient of the first-order projection is computed and projected onto a second direction specified by the user. By combining IR's from Boxster (pressure mic), grad_Boxster (first-order mic), and grad2_Boxster (second-order), it should be possible to simulate any type of mic setup and combination of setups in any room that could be considered to be a box. Starting with dry, monophonic recordings made in a dead room, one should be able to simulate very sophisticated mic setups in a concert hall, then assemble them into a mix, simulating an ensemble recording, all with a physically consistent model. The demo contrasts simulation of nearly coincident pressure- gradient mics (grad_Boxster) in a 12,500 m3 concert hall versus binaural omni pressure mics (Boxster, no HRTF) in the same hall with the same separation between mics for both. The only difference for the first half of the demo is whether or not the gradient is computed, yet the sounds are very different both with speakers and with headphones (esp. the latter). In the second half, the positions of the guitars are slightly different (maximal separation for either). --------------------------- In short, grad_Boxster can be used to simulate ordinary stereo recordings (Blumlein, etc.) in the same manner that Boxster can be used for simulating binaural recordings, complete with reverb, echo, stereo separation, and so on --- but with physical consistency. As a side effect, both new programs provide other "knobs" for extending sample generation capability. All programs can be run either from a PyGtk GUI or from the command line. Regards to all, Dave Dave Clark

[linux-audio-announce] FW: l.o.s.s - open source sound project

by jake harries

----Original Message----- From: Ed Carter <ed(a)lowtech.org> To: Multiple recipients of list SONICARTSNET <sonicartsnet(a)sheffield.ac.uk> Sent: Tue, 14 Feb 2006 21:40:19 GMT Subject: l.o.s.s - open source sound project [Apologies for cross-posting, please circulate where appropriate.] http://loss.access-space.org The l.o.s.s project promotes and supports the use of free, open source music software, in conjunction with Creative Commons (CC) licensing which accepts and encourages sharing. As well as a CD of curated work (also available for free download), the project's online presence is intended to become a focal point for artists working with open source software, and releasing their work through CC licenses. Please visit the website for details of how to contribute tracks. The aim of the project was not to portray any kind of 'open source' sound, but to offer an array of some of the interesting work people are creating with what is available. The result is an incredibly diverse compilation of internationally renowned artists, encompassing electronica, soundscapes, hiphop and electro-acoustic amongst other styles. Contributions for the CD include work by Nullpointer, Ava, Edge Effect, Jake Harries, Collective Motion, Panayiotis Kokoras, DJ Auto, Chaos Butterfly, Slub, Minimal Turntablist Crew and Elektronengehirn. Even the artwork was produced using open source techniques by Matt Gray (Ava), and the album was mastered at Mirror Image Studios in Minneapolis, again, using the Linux operating system and libre software. The project is run by the registered charity Access Space, a free media lab based in Sheffield, promoting open source software and using recycled hardware.

[linux-audio-announce] [ANN] E-Radium V0.61e and Das_Watchdog V0.2.0

by Kjetil S. Matheussen

Download from http://ccrma.stanford.edu/~kjetil/src/ ***************************************************** E-radium -------- E-radium is Radium and a special version of E-UAE (with support for realtime scheduling and alsa midi). Radium is a unique type of music event editor made to be efficient and give all sorts of possibilities. The user interface is inspired by trackers, but Radium is generally a lot more versatile and can be used for all kind of genres. http://www.notam02.no/radium/ Warning: E-radium does not seem to work on 64bit machines. :-( Changes 0.61d->0.61e -------------------- -Run XInitThreads(). Should fix e-radium in case you got xlib async errors. (Fix for SMP machines) **************************************************** Das_Watchdog ------------ Das_Watchdog is a general watchdog for the linux operating system that should be run in the background at all times to ensure a realtime process won't hang the machine. Changes 0.1.2->0.2.0 --------------------- * Don't do anything if no process priorities are changed, when watchdogging. * Added the --force option, that sets the priority of all timer processes to FIFO/99. * Added the das_watchdog /etc/init.d script provided by Stefan Kersten. (das_watchdog.rc) * Added the --verbose option. * Check that its the same process when setting back old priority. * Don't set back to old priority if the priority has been changed in the mean time. * Added options for setting increasetime, checktime and waittime. (--increasetime, --checktime and --waittime) * Don't change the priority of any timer process when watchdogging. * Smaller code cleanups.

[linux-audio-announce] [ANN] das_watchdog 0.1.2

by Kjetil S. Matheussen

Sorry for all the announcements. I think I got it right now. ;-) I have fixed up the compilation problems, corrected the DISPLAY environment variable, and let both the program and makefile give warning/error if the softirq-timer/0 or ksoftirqd/0 processes aren't set to have highest priority. It might still not work, but at least you get a message about /why/ it doesn't work, and what you can do to fix it. (Running "chrt -f -p 99 `ps -A |grep softirq-timer/0 |awk '{print $1}'`" for all processors (change the "0" in "softirq-timer/0" for each additional processor) is probably a good tip to make it work.) REQUIREMENTS ------------ xmessage (should be a part of X11) libgtop2 (should be a part gnome. No, das_watchdog is not a gnome-program.) CHANGES ------- 0.1.0->0.1.2 * Added check for the ksoftrqd/0 process as well as the softirq-timer/0 process. * Added check for SCHED_OTHER of the timing process as well as priority. * Removed debug-printing. * Added extensive checks both when compiling and when running about the priority of the "softirq-timer/0" process: - ***If "softirq-timer/0" is not set to a very high priority (99), the watchdog most probably will not work.*** - The default priority for softirq-timer/0 seems to be 1. However, for real time work, it must be set higher to get reliable timing. Set it to 99. - If softirq-timer/0 is set to less than 99, das_watchdog will refuse to compile unless you force it to by editing the makefile. When running das_watchdog, it will only give a warning if the priority is set too low. * Changed the DISPLAY environment variable to ":0.0" instead of "localhost:0.0". Seems to work for everyone now. * Switched from libgtop to libgtop2. Download from http://ccrma.stanford.edu/~kjetil/src/

[linux-audio-announce] Rivendell v0.9.66

by Fred Gleason

I'm pleased to announce the release of Rivendell v0.9.66. Rivendell is a full-featured Radio Automation System that is available under the GNU General Public License. From the NEWS file: *** snip snip *** Changes: CD Ripper Enhancements. Major enhancements have been made to the CD ripper functionality in the RDLibrary module, including: CD-TEXT Support. The rippers now use CD-TEXT data in preference to the FreeDB. If no CD-TEXT data is found on a disk, then the FreeDB is searched as before. International Standard Recording Code (ISRC) Support. If found, the rippers will now record the ISRC string from each track. These strings can be viewed and/or edited in the 'CutInfo/Record' dialog box. Automatic Cart/Cut Generation. In the Full Disk ripper, it's now possible to rip an entire CD into the system with just a few mouse clicks. This can be done on a track-by-track basis by clicking the 'Add New Cart' button in the Select Cut dialog, or for all the tracks at once by clicking the 'Set All New Carts' button. New Build Targets. It's now possible to build Rivendell as a Slackware package by doing 'make slack' (requires the Slackware packaging tools) or as a SLAX module by doing 'make slax' (requires the Linux-live scripts and the Slackware packaging tools). RDCatch Enhancements. The previous hard-coded system-wide limit of 16 RDCatch decks has been removed, making it possible to configure and use an arbitrarily large number of decks. Miscellaneous Bugfixes. See the ChangeLog. Library Versions: This version requires that, at a minimum, libradio-0.96.1 and librhpi-0.94.5 be installed. If installing from RPM, the version of the currently installed libraries can be determined by doing: rpm -q libradio rpm -q librhpi Database Update: As always, be sure to run RDAdmin immediately after upgrading to allow any necessary changes to the database schema to be applied. *** snip snip *** Further information, including download links can be found at: http://www.salemradiolabs.com/rivendell/ Cheers! |-------------------------------------------------------------------------| | Frederick F.
