[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.

[linux-audio-announce] Bleepfest: London, UK

by John Littler

Hi All, I don't know how many of you are in or near London, England but we're having an event called Bleepfest in the crypt of Christchurch Spitalfields near Spitalfields Market. Here's the promo ... as a general note, What: Computer and electronic music demo day When: March 25th from 5 PM to 10 PM (these hours might increase) Where: London! Christchurch Spitalfields Crypt, by the market a few minutes from Liverpool St Station Who: musicians, bedroom or serious, boppers, thinkers, listeners Music Genres: unlimited! entry: UK2 Bleepfest 06 will be a part-day and night event that will be like the Demos of old and where people can have the option to display what they're doing "off stage" to small groups around them or to plug into the PA and be an "event". Events will have time spaces between them so that everybody else isn't drowned out. The object is to attract people who like to play with music as well as people who are quite serious about it. The object is also to create a fun and friendly environment where people can wander around and get new ideas. While the event is operating system agnostic, and there are Linux people already signed up to come along, it would be nice to have more, and in particular if people want to run advocacy tables or whatever, that would be most welcome. The only charge will be the small entry fee. for more info: http://mstation.org/bleepfest or email me Cheers John

[linux-audio-announce] ANNOUNCE: Rosegarden-4 1.2.3 released

by Chris Cannam

The Rosegarden team are delighted to announce the release of version 1.2.3 of Rosegarden 4, an audio and MIDI sequencer and musical notation editor for Linux. Rosegarden is among the largest and most insanely ambitious Linux music software projects, and is the only Linux application to offer full composition and recording capabilities to musicians who prefer to use classical notation. http://www.rosegardenmusic.com/ The long-awaited 1.2.3 release of Rosegarden-4 offers a variety of new features, bug fixes and enhancements. These include: * The main segment canvas has been rewritten and is now faster, more responsive, more accurate, and marginally prettier than before. (This work proved much more complex than hoped, and accounts for much of the time spent since the 1.0 release a year ago.) * A new percussion matrix editor has been added. MIDI devices can have user-configurable percussion key maps, stored in the same device files as bank and program definitions. Users are invited to contribute their own. * Multi-track audio recording and simultaneous recording of audio and MIDI are now supported. * A "project packager" has been introduced and integrated, facilitating the exchange of complete Rosegarden projects including associated audio data and any other required files. * The Lilypond export function has been updated for Lilypond 2.6 and features a new Preview mode. * You can now control Rosegarden's mixer and other twiddly bits using an external MIDI controller device such as the Behringer BCF2000. * Rosegarden is now capable of synchronising to MIDI Time Code in master and slave modes (thanks to Vince Negri). MMC master and slave are also now supported. * Rosegarden's ALSA MIDI ports can now be connected and controlled using an external ALSA connection manager such as qjackctl (thanks to Pedro Lopez-Cabanillas). * The default sequencer timer selection should be better behaved than in 1.0 (eliminating the dreaded "Rosegarden only plays the first note" problem). * Effects plugins can now be applied to groups of audio instruments at the buss stage. * Many new icons and improved versions of old icons have been added (thanks to Vladimir Savic). * The build system now uses scons instead of autotools. This release also sees hundreds of bug fixes, including fixes to some long-standing issues with DSSI plugin support, JACK transport synchronisation, and punch-in recording. For more information about Rosegarden and what it can do for you, please see http://www.rosegardenmusic.com/ Rosegarden is Free Software under the GNU General Public License.

[linux-audio-announce] [ANN] das_watchdog 0.0.1 and jack_capture v0.2.3

by Kjetil S. Matheussen

Download from http://ccrma.stanford.edu/~kjetil/src/ Das_Watchdog ============ ABOUT ----- Das_Watchdog is a program heavily and shamefully inspired by the rt_watchdog program made by Florian Schmidt: http://tapas.affenbande.org/?page_id=38 However, this one has some improvements: 1. It works with 2.4 kernels as well as 2.6. (well, at least I think it works with 2.6...) 2. Instead of permanently setting all realtime processes to run non-realtime, das_watchdog only sets them temporary. 3. When the watchdog kicks in, an X window should pop up that tells you whats happening. (just close it after reading the message). INSTALLING ---------- make cp das_watchdog /usr/local/sbin/ echo '/usr/local/sbin/das_watchdog & >/dev/null' >>/etc/rc.local reboot REQUIREMENTS ------------ tcl/tk. (http://en.wikipedia.org/wiki/Tk_(computing)) Jack_capture ============ ABOUT ----- jack_capture is a small simple program to capture whatever sound is going out to your speakers into a file. This is the program I always wanted to have for jack, but no one made. So here it is. CHANGES ------- 0.2.2 -> 0.2.3: *Added -z argument that choose number of leading zeros. *Various changes.

[linux-audio-announce] fastbreeder (a genetic programming synth)

by Dave Griffiths

An experimental genetic programming synthesiser. This program is free software, developed for linux, using jack for audio. Fastbreeder is essentially a 4 button synth. The idea is to grow code by choosing from a range of automatically generated variations of functions, you don't have to know how they work, but each function creates a sound which can be selected by you. The following generation is then created containing mutants of your chosen sound. You can refine and develop the sound just by auditioning and choosing the best one each time. http://www.pawfal.org/Software/fastbreeder/ For those in the London UK area, I'm doing a short show and tell of this app at the next dorkbot: http://dorkbot.org/dorkbotlondon/ cheers, dave

[linux-audio-announce] CLAM 0.90 Released

by Pau Arumi

Wed Feb 8 2006 CLAM 0.90 Released ====================================== ´New multiplied build-system, fancy applications and inter- connectivity' What is CLAM? CLAM is a framework for research and application development in the Audio and Music Domain. It offers a conceptual model as well as tools for the analysis, synthesis and processing of audio signals. We are glad to announce that our new 0.90 release is already available at our (also brand new) website: http://clam.iua.upf.edu. This release represents a big step forward to our soon to come first stable 1.0 release and includes major improvements. For the first time the CLAM framework and all related applications are available in binary form for all major platforms: deb packages are provided for Ubuntu/Debian GNU/Linux, dmg images for Mac OSX and setup executables for Windows. This change has represented a complete but necessary (and painful!) rework of our build system, which is now based on small binary libraries and uses Scons as the build tool. We expect it to reduce drastically the complexity of the compilation and installation of clam applications for the end-user. Other major improvements include a complete rework of the SMSTools, application GUI, which is now based on Qt, as well as many additions to the Annotator app. A CLAM Network can now also become an Open Sound Control (OSC) node, opening up the possibility of interconnection to external applications. In the 'Application Prototyping' chapter we'd like to mention that we have also added complete tools to create both VST and LADSPA plugins out of a previously designed network. It is also worth noticing the possibility of creating stand-alone applications with a GUI created using the great Qt-designer and the CLAM Qt-plugins. Such standalone applications can behave either as a Jack client (for GNU/Linux and Mac OSX) or use audio backends like alsa or Portaudio. Please read these and other improvements in the attached changelog and visit our website and/our mailing list for further announcements. Although we are continuing to work toward the 1.0 release and we expect to come up with new improvements soon, we hope all these additions already convert the framework into a more usable and useful tool and, as always, we expect as much feedback as possible from all our users. The CLAM team CLAM ChangeLog 2006-02-07 CLAM_0_90_0 'New multiplatform build-system, fancy applications and interconnectivity' * Building and packaging + New build system based on scons + Binary libraries + Standard library installation + CLAM applications just link against the libraries + CLAM and all provided applications are working multiplatform (Linux/MacOSX/Windows) + Easy to use installers for MacOSX, Windows and Linux (Debian) + Ported to g++ 4.0 * Rappid prototyping infrastructure + New external-generators/sinks and external-control-senders/receiver classes. o They glue specific architecture (jack, portaudio, ladspa, vst) ports with a clam network. * New hierarchy of network-players classes, with these (final) classes: + JACKNetworkPlayer, + PortAudioNetworkPlayer, + BlockingNetworkPlayer, * LADSPA Plugins (Linux): A generic plugin that embeds a network can be easily created by just providing the path to a valid network xml file. * VST Plugins (Mac/Windows): A generic plugin that embeds a network can be easily created by just providing the path to a valid network xml file. * OSC (Open Sound Control): A network (for instance from the Network Editor) can now send an receive OSC messages and interconnect to other applications that follow this protocol. * MIDI files + New classes to read/write standard MIDI files * Qt Visualization Module + Support for multidisplay plots. + BPFEditor: multiple BPF allowed + Faster rendering of plots using buffered pixmaps * QtSMSTools2: New! A total rewrite of SMSTools2 GUI using the Qt toolkit. + Multidisplay implementation sharing common axis o Spectrogram (Color,Black&White) o Improved player: audio and fundamental frequency o More suitable dialogs to configure projects * NetworkEditor + New callback audio-driving mode. This allow different modes (specified as command line options) o Jack client mode (not in Windows) o PortAudio mode o Blocking mode * Annotator + New segment editor: o Different annotation restrictions depending on the schema. Right now: # Continuous segmentation (no gap) # Discontinous segmentation (gaps but not overlaps) o Consistent dragging o Tooltips are faster to appear o Tooltips say just the position of the hovered element instead the cursor position. o Hovering highlights the limit + Optimizations on the song switching and on the display + Inserting and removing segments now has its reflexion on the pool + Playing the wav and the auralization on different channels. + Description schema browser + Now, viable projects can be built from the interface * Spectral Analysis Synthesis + FFTOoura: o By defining a compilation flag, FFTOoura can be choosen instead of fftw by default o FFTOoura is now also implemented in the inverse FFT process 2005-07-21 CLAM_0_8_0 'Prototyper with streaming SMS transformations' * SMS Transformations on the network editor: + All SMS Transformations have been refactored in order to work in streaming mode and not only in offline mode. * New Prototyping way: + Prototyper: Allows to bind a Qt desinger interface to a Network XML definition so you can have an CLAM GUI application up an running without a single line of code. Current features: o It uses the widget names and classes to Automagically relate widgets to processings, ports and controls. o Binds sliders, knobs and so to in-controls on the network o Binds monitoring plots to out-ports on the network o Binds buttons to play/stop actions on the network * QtPlots add-ons: + Editable segmentation marks on all the plots + QtSpectrogram: o Plot to view sonogram (Color/B&W) + BPFEditor: o Editable/auralizable plot (Audio and MIDI support) * Compiler compatibility: + CLAM and its applications now compiles in GNU g++3.4 (as well as 3.3) * Audio file I/O facilities: + MP3 I/O: Bug fixed: that prevented XING headers from being used to compute duration + MP3 I/O: Bug fixed in conversion from milliseconds to seconds + Vorbis I/O: Feature addition: now the # of samples is computed for Vorbis bitstreams * Memory leak review: + FFT internal buffer was not freed on destruction * XML related changes: + Now XmlStorage::Dump does indentation by default. A new optional parameter disables indentation. + XercesC 2.6 is required in order to pass the tests and be memory leak free (even 2.3 should be enough to compile and run CLAM). + XML Storage Error Handling (This solves issue #0000022): o Catchable CLAM::XmlStorageErr excepetions are thrown whenever: # I/O error happens # Malformed XML is readed # Read elements or contents does not match with CLAM objects structure # CLAM objects detect some semantic constraints. + XPath (like) navigation (This solves issue #0000045): o The implementation of XmlStorage::Select allows using: # XmlStorage::AppendToDocument(object, path, filename) # XmlStorage::RestoreFromFragment(object, path, istream) # Using atomic primitives for doing some similar hacks like writing fragments of the XML for an object to disk. + Alternative XML Backends (LibXml++) o Unification of the way XmlStorage interfaces the library dependant code. o LibXml++ Backend implemented. It is planned to be the default backend on future releases but still some work is needed to get the error messages correctly reported. * Network refactoring: + Published{In|Out}{Controls|Ports} -> {In|Out}{Control|Port}Registry * Descriptors: + SpectralDescriptors::HighFrequencyCoefficent -> HighFrequencyContent as specified by the original literature. * Other: + ConnectPorts overloaded to connect free ports (that is not belonging to any processing, normally used for injecting or extracting data) * Build System: + Changes in order to not abort ./configure script when some library is not found (and not specifyed with the --without-libname option) 2004-11-18 CLAM_0_7_0 'Easier deployment, better plots and Processing Networks' etc.
