by Patrick Shirkey

From the "Better Late than Never Dept"... Announcing the _*Linux Audio Musicians Best of 2010 mix*_ Download and view the full playlist of 116 tracks here: http://djcj.org/audio/lam/ Listen to the continuous radio stream here: http://radio.linuxaudio.org/lam2010.ogg.m3u **************************************************************************** Congratulations!!! to the Artists and Bands that made 2010 a bumper year for well produced and unique music from the Linux Audio Community. This mix is the biggest yet with over 100 tracks included and over 12 hours of music to listen to. A hefty selection of guitar music and rock productions are included in this years mix to complement the large range of electronica. The variation of styles and genres is superb and as expected there was lots of off the wall and challenging music produced during the 2010 period also. The playlist has been ordered in terms of Genre/Style to make it easier to separate the tracks out for those with specific tastes and to ensure the radio stream flows nicely. If you feel that there is a track missing please feel free to contact me with details. This is a snapshot of the year so lets make it as complete as possible. Enjoy! **************************************************************************** -- Patrick Shirkey Boost Hardware Ltd.

SuperCollider 3.4.2 released

by Dan S

Hi all - SuperCollider 3.4.2, released March 2011, is a bugfix release. Source code downloads: http://sourceforge.net/projects/supercollider/files/Source/3.4.2/ Ubuntu packages: https://launchpad.net/~supercollider/ Since SuperCollider 3.4, we’ve found and fixed quite a few bugs - including an important “garbage collection” problem which could cause the language to crash in some rare instances, and a cleanup of the regular-expression methods. We recommend users of 3.4 to upgrade to 3.4.2. More details on the wiki: http://supercollider.sourceforge.net/wiki/index.php/SuperCollider_3.4.2 Dan -- http://www.mcld.co.uk

[ANN] jack-stdout 1.0

by Robin Gareus

Hya, I've just brought jack-stdout up to scratch. jack-stdout captures audio from one or more JACK audio-ports and writes raw data to standard-output. It can write signed/unsigned 16/24bit integer and 32bit floating-point data, both big/little endian. * http://rg42.org/oss/jackstdout/ * git://rg42.org/jack-stdout example usage - live stream from JACK: jack-stdout system:capture_1 system:capture_2 \ | oggenc -r -R 48000 -B 16 -C 2 - \ | tee /tmp/recording.ogg \ | oggfwd -p -n "my live stream" localhost 5900 hackme live.ogg have fun, robin

[ANN] zynjacku-6

by Nedko Arnaudov

In this release: * Fixes and improvements that improve interoperability with these plugins: * The Composite Sampler * EQ10Q * Calf * Support the new dynamic manifest extension and thus NASPRO 0.2.90 * It is now possible to supply on commandline a regular expression instead of URI. The regexp must match only one URI. * Plugin GUI windows now have WM_WINDOW_ROLE set to "plugin_ui" (for WM kludges etc) * Various improvements in lv2 turtle rdf parsing * A commandline parsing bug that prevented use of state file is fixed * Better reporting and handling of ttl syntax errors * The plugin scanner got some speed an memory optimizations * It is now possible to build and use zynjacku on MacOSX * Windows of the generic GUIs are now smaller when the plugin is not dynparam one * The Author column is now named Maintainer to better match doap:maintainer semantics * Change installation layout to better suit Debian and hopefully other distros as well * In single plugin mode, exit if UI show failed * Properly handle scan when there are no lv2 plugins installed (patch by Orcan Ogetbil) https://bugzilla.redhat.com/show_bug.cgi?id=551480 * Fix syntax error exception. #15558 * When rack was being cleared, some plugin UI windows were not being closed. This bug was fixed. zynjacku is JACK based, GTK (2.x) host for LV2 synths. It has one JACK MIDI input port (routed to all hosted synths) and one (two for stereo synths) JACK audio output port per plugin. Such design provides multi-timbral sound by running several synth plugins. zynjacku is a nunchaku weapon for JACK audio synthesis. You have solid parts for synthesis itself and you have flexible part that allows synthesis to suit your needs. lv2rack is a host for LV2 effect plugins.

[ann] CAPS 0.4.5

by Tim Goetze

The C* Audio Plugin Suite reaches version 0.4.5. http://quitte.de/dsp/caps.html http://quitte.de/dsp/caps_0.4.5.tar.gz CAPS is a collection of refined LADSPA units covering a wide range of applications, from stompbox classics to experimental oscillators. CAPS is distributed as open source under the terms of the GNU Public License. -*- This release brings a new plugin, "Narrower", which reduces the perceived width of a stereophonic image. Frequent users of headphones will appreciate the increased subtlety of the listening experience as well as the reduced fatigue caused by "superstereo" recordings. Other than that, some minor bugs have been fixed and the accompanying PDF data sheet has been improved (frequency response plots now use log scale: http://quitte.de/dsp/caps-0.4.5.pdf ). The build configuration tool "configure.py" has been modified to handle python3's errant ways in graceful manner. Upgrading is recommended unless you have no need for the new plugin and the current version is working fine for you. -*- Enjoy, and thank you for using CAPS, Tim

NASPRO 0.2.90 released

by Stefano D'Angelo

Hi all, I'm glad to announce the release of NASPRO 0.2.90. NASPRO (http://naspro.atheme.org/) is meant to be a cross-platform sound processing software architecture built around the LV2 plugin standard (http://lv2plug.in/). The goal of the project is to develop a series of tools to make it easy and convenient to use LV2 for sound processing on any (relevant) platform and for everybody: end users, host developers, plugin developers, distributors and scientists/researchers. This release is a total redesign/rewrite that more or less reimplements the features of the previous release, but in a much cleaner and maintainable way. It includes: * NASPRO core: the portable runtime library at the bottom of the architecture; * NASPRO Bridge it: a little helper library to develop insert-your-API-here to LV2 bridges; * NASPRO bridges: a collection of bridges to LV2 which, once installed, allow you to use plugins developed for other plugin standards in LV2 hosts. In particular, the NASPRO bridges collection includes two bridges: a LADSPA (http://www.ladspa.org/) 1.1 and a DSSI (http://dssi.sourceforge.net/) 1.0.0/1.1.0 bridge. All of the code is released under the LGPL 2.1 (http://www.gnu.org/licenses/lgpl-2.1.html) license. More information is available on the project's website. Enjoy! Stefano D'Angelo

first release of flarps

by Lieven Moors

I would like to announce the release of flarps-0.1.0 Flarps is an arpeggiator for Linux. It uses JACK MIDI to generate melodies, and it can be controlled live by editing a text file in a simple text-editor. Flarps is designed around the notion of 'steps'. A step describes the relative distance between two MIDI notes, and has a horizontal and a vertical component. Vertically, a difference in pitch is specified, and horizontally a distance in time (rhythm). You can find a lot more information about flarps here: http://flarps.sourceforge.net/ You can download it directly at: http://sourceforge.net/projects/flarps/files/flarps-0.1.0.tar.bz2/download Or you can clone the git repository with: git clone git://flarps.git.sourceforge.net/gitroot/flarps/flarps For bug reports, feature requests, support requests etc., please use the facilities at the sourceforge project site. New ideas or patches for this project are very welcome. If you want to collaborate on this project, you can find me on the linux-audio-dev mailing list. lievenmoors

LV2 4.0

by David Robillard

LV2 4.0 is out. More information about LV2 can be found at: http://lv2plug.in This release is a significant one, fixing many problems and introducing a new standard (though optional) method of depending on LV2 extensions. In particular, it is now possible to install system-wide extensions and build against them using a standard include style (without requiring a central authority on extension package names). The lv2core package, as of this version, includes a utility called lv2config that makes this possible. See http://lv2plug.in/docs/index.php?title=Using_Extensions_in_Code for details. Changes (non-exhaustive): * Make doap:license suggested, but not required (for wrappers) * Define lv2:binary (MUST be in manifest.ttl) * Define lv2:majorVersion and lv2:minorVersion (MUST be in manifest.ttl) * Define lv2:documentation and use it to document lv2core * Add lv2:FunctionPlugin and lv2:ConstantPlugin classes * Move lv2:AmplifierPlugin under lv2:DynamicsPlugin * Loosen domain of lv2:optionalFeature and lv2:requiredFeature (to allow re-use in extensions) * Add generic lv2:Resource and lv2:PluginBase classes * Fix definition of lv2:minimum etc. (used for values, not scale points) * More precisely define properties with OWL * Move project metadata to manifest * Add lv2:enumeration port property. * Define run() pre-roll special case (sample_count == 0). Release tarball is available at: http://lv2plug.in/spec/lv2core-4.0.tar.bz2 Documentation for LV2 core is available at: http://lv2plug.in/ns/lv2core <http://lv2plug.in/ns/lv2core/> Share and enjoy, -dr
