Ubuntu Studio is a multimedia editing/creation flavor of Ubuntu, built for the GNU/Linux audio, video, and graphics enthusiast or professional. http://www.ubuntustudio.org The Ubuntu Studio team is proud to announce its sixth release: Ubuntu Studio 9.10 "Karmic Koala". With this release, which you can download in a 1.4GB DVD, Ubuntu Studio offers a pre-made selection of packages, targeted at audio producers, video producers and graphic designers. Ubuntu Studio greatly simplifies the Linux-based multimedia workstation. Downloads of the install DVD are available here: http://cdimage.ubuntu.com/ubuntustudio/releases/9.10/release For Ubuntu Studio 9.10 we have continued to grow our feature set, update packages, and fix critical bugs to better the Ubuntu Studio user experience. We are happy to announce that the real time kernel will be an official upstream release patch. It will be installed by default if the audio task is selected. We have tested it heavily and are very happy with it's performance in audio environments. Features/Improvements: * Official upstream RT kernel release (i.e. it's very stable) * Font meta package added to the graphics meta, which installs literally hundreds of free fonts * Xwax (http://xwax.co.uk) and a2jmidid (http://home.gna.org/a2jmidid/) packaged and added to the audio meta-package * Xjadeo (http://xjadeo.sourceforge.net/) added to the video meta * Network tools like NetworkManager and Pidgin will be available on the DVD disc repository but not installed by default * Firewire libraries are now upgraded to 2.0 * MANY newer versions of applications (Ardour, Gimp, Blender, Inkscape, Audacity, Kino, Scribus, Denemo, Hugin, etc...) for exact versions please see: http://packages.ubuntu.com See the Ubuntu release notes for other non Ubuntu Studio specific changes. As our wiki page at https://wiki.ubuntu.com/UbuntuStudio states, "our aim is to make it more accessible for new users to get into the tools that GNU/Linux has to offer for multimedia creation and production. We also want to spotlight what's out there, and show users tools they might not know to exist." Thanks to all who helped in Ubuntu Studio 9.10's creation!

VamPy: Vamp plugins in Python

by Chris Cannam

VamPy, a Python wrapper for the Vamp plugin API, is now available. Using VamPy you can write audio analysis or visualisation plugins for use in Vamp hosts with a quick and dynamic environment that is somewhat like working in Matlab or other high-level modelling environments. VamPy has full two-way support for NumPy, an efficient numerical library for Python, and for the dynamic typing of Python. You can download VamPy from : http://www.vamp-plugins.org/vampy.html VamPy was written by Gyorgy Fazekas at the Centre for Digital Music, Queen Mary University of London and is published under a BSD-style license.

QM Vamp Plugins v1.6.1 now available

by Chris Cannam

[Note: This announcement is about closed-source software] Version 1.6.1 of the QM Vamp Plugins -- a set of audio analysis plugins in the Vamp plugin format, developed at the Centre for Digital Music at Queen Mary, University of London -- is now available for download. Plugins included are note onset detector, beat and barline tracker, tempo estimator, key estimator, tonal change detector, structural segmenter, timbral and rhythmic similarity, wavelet scaleogram, adaptive spectrogram, note transcription, chromagram, constant-Q spectrogram, and MFCC calculation. This is a bug-fix release, fixing a failure to correctly smooth the onset detection function which caused the onset and beat tracking plugins occasionally to miss onsets or find spurious ones. For downloads, please see: http://isophonics.net/QMVampPlugins The plugins are available in binary form only and may be freely used for any purpose, and redistributed for non-commercial purposes only. Supported platforms are 32- and 64-bit Linux, 32-bit Windows, and OS/X 10.4 or newer (Intel/PPC universal). For documentation of these plugins, please see: http://www.vamp-plugins.org/plugin-doc/qm-vamp-plugins.html Chris

introducing l2ork

by Ivica Ico Bukvic

Greetings all, I wanted to share with you my latest Linux-based and Linuxaudio.org-related project that has been sucking up most of my time over the past year or so to the point it seemed as if I have disappeared off the face of the Earth. Needless to mention it continues to alter my sleeping/eating patterns with unprecedented aptitude and with no end in sight ;-). http://l2ork.music.vt.edu/ Best wishes, Ivica Ico Bukvic, D.M.A. Composition, Music Technology Director, DISIS Interactive Sound & Intermedia Studio Assistant Co-Director, CCTAD CHCI, CS, and Art (by courtesy) Virginia Tech Dept. of Music - 0240 Blacksburg, VA 24061 (540) 231-6139 (540) 231-5034 (fax) ico(a)vt.edu http://www.music.vt.edu/faculty/bukvic/

[ANN] Ecasound 2.7.0 released

by Kai Vehmanen

Hello all, Ecasound 2.7.0 has been released! Releases notes follow: 0. Special note: Ten years of Ecasound! --------------------------------------- This is the 10th year anniversary release for Ecasound! The first public version, 1.1.4r1, of Ecasound, licensed under GPL, was released on 30th June 1999. See the following mailing list post for a quick rundown of what has happened so far: - http://eca.cx/ecasound-list/2009/07/0004.html 1. Summary of changes in this release ------------------------------------- Initial Open Sound Control (OSC) interface for parameter control has been added. New '-chorder' and '-eadb' options, and 'cop-get' interactive mode command, have been added. Optional build time support has been added for using liboil to optimize inner loops, giving a small performance boost to many common use-scenarios. Various bugs fixed in JACK support, mp3 output and option parsing. Fixes to build problems in Mac OS X. 2. What is Ecasound? -------------------- Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. Ecasound supports a wide range of audio inputs, outputs and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console mode user-interface is included in the package. Primary platform for running Ecasound is GNU/Linux. Ecasound can also be run on many UNIX-derived systems such as FreeBSD, Mac OS X and Solaris. Limited support for Windows is available through Cygwin. Ecasound is licensed under the GPL. The Ecasound Control Interface (ECI) is licensed under the LGPL. 3. Changes in 2.7.x series -------------------------- v2.7.0: * Open Sound Control (OSC) support. See the initial announcement mail sent to ecasound-list: http://eca.cx/ecasound-list/2009/04/0036-fixed.html Current interface is documented at: http://eca.cx/ecasound/Documentation/ecasound_osc_interface.txt The interface is still limited and subject to change in later releases, but it's a start. * New '-chorder' operator that allows to reorder channels of an audio stream. Also duplication and omission of certain channels is possible. See ecasound(1) man page for more information. * Added new amplify/gain variant '-eadb' that allows to specify the gain in dB. See the related mail thread: http://eca.cx/ecasound-list/2009/03/0034.html * Refactored POSIX signal handling in ecasound. See the following mail for some rationale, as well as a list of changes. See mail thread: http://eca.cx/ecasound-list/2009/02/0027.html * Various optimizations to Ecasound inner loops using the liboil library. See http://liboil.freedesktop.org/wiki/ To enable the optimizations, liboil-0.3 development files need to be installed and '--enable-liboil' must be passed to Ecasound's configure script. * New 'cop-get' interactive mode command. See the updated ecasound-iam(1) manual page for further info. Full list of changes is available at: - http://www.eca.cx/ecasound/history.php 4. Interface and configuration file changes in 2.7 series --------------------------------------------------------- v2.7.0: Output of '-ev' operator has been renewed. The name for default chainsetup created from command line is now "untitled-chainsetup". Most of the entries in the installed ecasoundrc file (in ${prefix}/share/ecasound/ecasoundrc), are now commented out by default. Major changes to the libecasound library public interface. This should not really affect anyone anymore, as direct use of libecasound has been discouraged for a long time and it is available only as a static library, but just in case someone is still using it. See libecasound/ChangeLog for a detailed list of changes. 5. Contributors to 2.7 series ----------------------------- Patches - Accepted code, documentation and build system changes ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Extracted with 'git-shortlog -s': v2.7.0: - Adam Linson (1) - Jeremy Hughes (1) - Junichi Uekawa (1) - Kai Vehmanen (203) Bug Hunting - Reports that led to bugfixes (items closed) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ v2.7.0: * Oliver Oli (2) various bugs in new OSC support * RProgrammer @ sf.net (1) uninstall target broken on OS X (sfbug:1283448) * Jason Galyon (1) frontend parser bug for '-E' option Feature suggestions - Ideas that led to new features (items) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ v2.7.0: * Julien Claassen (1) OSC support * Klaus Schulz (1) -eadb chainop 6.

Second version of alsa-midi-latency-test released (v0.0.2)

by Jakob Flierl

Hi LAA, the second release (v0.0.2) of "alsa-midi-latency-test" is available at: http://github.com/koppi/alsa-midi-latency-test/ alsa-midi-latency-test measures the roundtrip time of a MIDI message in the alsa subsystem of the linux kernel using a high precision timer. It calculates the worst case roundtrip time of all sent MIDI messages and displays a histogram of the rountrip time jitter. The console application aims to become a Linux drop-in-replacement for the windows application "MidiTest": http://earthvegaconnection.com/evc/products/miditest/index.html The second release of alsa-midi-latency-test includes a number of bug fixes with the high precision timer code. It also includes some benchmark results for future reference: http://github.com/koppi/alsa-midi-latency-test/tree/master/benchmarks/ Any kind of feedback is greatly appreciated. Kind regards, ++Jakob
