Dear all, Strasheela is a highly expressive constraint-based music composition system. Users declaratively state a music theory and the computer generates music which complies with this theory. A theory is formulated as a constraint satisfaction problem (CSP) by a set of rules (constraints) applied to a music representation in which some aspects are expressed by variables (unknowns). Music constraint programming is style-independent and is well-suited for highly complex theories (e.g. a fully-fledged theory of harmony). Results can be output into various formats including MIDI, Lilypond, and Csound. This release fixes a serious bug: before, Strasheela only worked when IOzSeF (an Oz extension for constraint solvers) was installed. It simplifies the installation on Windows by providing an installation batch file. It also adds a collection of ready-made constructors for musical segments such as contrapuntual lines, homophonic chord progressions, or specific motifs, and adds a number of harmony- related constraints. Further additions and bug fixes have been made as well. For more information on Strasheela, please visit http://strasheela.sourceforge.net/ Changes are described at http://strasheela.sourceforge.net/strasheela/doc/Changes.html This release can be downloaded from: https://sourceforge.net/project/showfiles.php?group_id=167225 Best Torsten -- Torsten Anders Interdisciplinary Centre for Computer Music Research University of Plymouth Office: +44-1752-586219 Private: +44-1752-558917 http://strasheela.sourceforge.net http://www.torsten-anders.de

Sonic Annotator v0.2 released

by Chris Cannam

Sonic Annotator is a utility program for batch feature extraction from audio files. It runs Vamp audio analysis plugins with specified parameters on audio files, and writes the result features in a selection of formats, in particular as RDF using the Audio Features and Event ontologies. Version 0.2 is now available, offering more stable and predictable results than the earlier 0.1. For more details and for downloads, please see http://www.omras2.org/SonicAnnotator Sonic Annotator was developed at the Centre for Digital Music, Queen Mary, University of London. It was funded by the EPSRC through the OMRAS2 project and is Free Software published under the GNU General Public License. Chris

Vamp Plugin Tester: a simple test utility for Vamp plugin development

by Chris Cannam

Announcing v0.1 of the Vamp plugin tester, a simple program that loads and tests Vamp audio feature extraction plugins for various common failure cases. It can't check whether you're getting the right results, but it can help you write more resilient and better-behaved plugins. Source code: http://downloads.sourceforge.net/vamp/vamp-plugin-tester-0.1.tar.bz2 OS/X universal binary: http://downloads.sourceforge.net/vamp/vamp-plugin-tester-0.1-osx-universal.… Windows binary: http://downloads.sourceforge.net/vamp/vamp-plugin-tester-0.1-win32.zip For more information about Vamp plugins, please see http://vamp-plugins.org/. The "home page" for this utility is the developer page at http://vamp-plugins.org/develop.html . There is some documentation for this program in the README file, but the short version is that you run it at a command prompt with the library name and plugin name, colon-separated, as an argument: $ ./vamp-plugin-tester vamp-example-plugins:spectralcentroid ... and see what it has to say about your plugins. It may also crash; if it crashes in the middle of one of its tests, that usually means that your plugin has crashed when faced with some unexpected input (run it in a debugger, or a memory checking utility if you have one, to find out where). This tester does report some genuine bugs when run against several of the existing Vamp plugins. I'll be aiming to make some fixes where I'm able. This is only the first release, so it's quite likely that the tester hasn't been tested enough itself yet. Please report any problems to me or the Vamp plugins develoment forum at http://vamp-plugins.org/forum/index.php/board,1.0.html . Chris

Rivendell v1.3.0

by Fred Gleason

On behalf of the entire Rivendell development team, I'm pleased to announce the release of Rivendell v1.3.0. Rivendell is a full-featured radio automation system targeted for use in professional broadcast environments. It is available under the GNU General Public License. Changes in this release include (from the NEWS file): *** snip snip *** Changes: Podcast System Enhancements. Support has been added to allow interoperation with third-party podcast traffic measurement and verification systems. It is also now possible to override the default ordering of episodes and configure automatic redirection of feed subscriptions. RDLogManager Enhancements. It is now possible to configure log import under-/over-fill warnings even for non-autofill events. When generating import warnings, RDLogManager will now warn if the dayparting parameters would cause a scheduled event to be unplayable at its scheduled time. An overall length counter has also been added for the Pre- and Post-Import lists in the Edit Event dialog. New RML. A new 'Message Box' ['MB'] RML has been added that allows a popup message to sent to any Rivendell workstation. (Be sure to see the 'MESSAGE_BOX.txt' file for information on configuring X11 to work properly with this feature). RLM Changes. An 'rlm_album' field has been added to the metadata fields and the API version incremented to '1'. A new plugin ('rlm_ando') has been added to allow interconnection with the Ando Media Ad Injector System. Bugfixes. See the ChangeLog for details. Database Update: This version of Rivendell uses database schema version 174, and will automatically upgrade any earlier versions. To see the current schema version prior to upgrade, see RDAdmin->SystemInfo. 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, screenshots and download links are available at: http://www.rivendellaudio.org/ Cheers! |-------------------------------------------------------------------------| | Frederick F.

Sonic Visualiser v1.5 now available!

by Chris Cannam

Sonic Visualiser is an application for inspecting and analysing the contents of music audio files. It combines powerful waveform and spectral visualisation tools with automated feature extraction plugins and annotation capabilities. Version 1.5 of Sonic Visualiser is now available. http://www.sonicvisualiser.org/ This release contains a small number of new features and a larger number of bug fixes over the previous 1.4 release. For more details, please read the release notes at: https://sourceforge.net/project/shownotes.php?release_id=668854 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, slow down playback while retaining display synchronisation, and show the ongoing alignment in time between multiple recordings of a piece with different timings. Sonic Visualiser supports the Vamp plugin API for plugins that extract descriptive or analytical data from audio. Vamp plugins for onset, pitch and note detection, tempo tracking, chromagram analysis, constant-Q spectrogram, spectral centroid, power curve, key estimation, tonal change detection, harmonic spectrogram, structural segmentation, timbral similarity, audio alignment calculation and a large number of low-level spectral features are available. There is also a comprehensive SDK for use by developers of Vamp plugins and hosts. For more information about Vamp plugins, please see: http://www.vamp-plugins.org/ Sonic Visualiser was developed at the Centre for Digital Music, Queen Mary, University of London: http://www.elec.qmul.ac.uk/digitalmusic/ Ongoing work on Sonic Visualiser and audio feature representation in the semantic web is carried out as part of the OMRAS2 project funded by the EPSRC. See http://omras2.org/ for more information. Sonic Visualiser is Free Software distributed under the GNU General Public License. The 1.5 release is available now in source code form or as binaries for Linux, OS/X, and Windows. Chris
