[linux-audio-announce] [ANN] GStreamer graphical pipeline editor released

by Andy Wingo

GStreamer Pipeline Editor "Thanks for all the fish" 0.2.0 released A first release of gst-editor, the GStreamer graphical pipeline editor, is now available for public consumption! This tool allows easy, graphical construction, inspection, and operation of media processing pipelines. It can be used as a rapid prototyping tool as well as a method to learn more about [1]GStreamer. More information about gst-editor is available on the project's [2]home page. Work on gst-editor was originally started in 2000 by Erik Walthinsen, but was left unfinished and unmaintained for a year or two. Development was picked up in mid-2002 by Andy Wingo, resulting in a port to Gnome 2, adaptation to the current GStreamer API, and general UI improvements and modularization. While much progress has been made in the area of stabilization, crashes still occur from time to time. Reproduceable bugs should be reported to [3]Gnome bugzilla. To rehash, for the impatient: THIS CODE IS VERY ALPHA. Screenshots * Thomas Vander Stichele took [4]this shot while designing the pipeline topology for a radio station mixing project: "It shows two decoding threads that read files from disk, connected to an adder, which does threaded output (in the actual app, osssink is replaced again by tee, which sends data to various output methods). "After some experimentation, this seemed to be the ideal pipeline setup, which I was able to verify by setting the whole pipeline to play (using the buttons at the bottom), then only pausing the adder (as shown in the screenshot - see the adder being in pause and everything else in play). Pressing pause here kept osssink playing for a little bit more until the queue is empty. In the app, this gives me the time to disconnect an input pipe, or connect a new one, with the adder being paused, so as to have seamless playback." * Andy made [5]this shot while playing around with [6]LADSPA plugins. Note the automatically generated controls for element properties, as well as the quick launch palette showing all available elements. Download gst-editor requires GStreamer 0.4.1. It could probably work with 0.4.0, but that is untested. You can find the source release of gst-player in [7]tar.gz format. RPM packages will be available from our [9]apt for rpm repository, and Debian packages should be coming soon to an experimental near you. Maintainer needed Andy is heading off to teach physics in rural Namibia for two years. Needless to say, he won't be doing much development on the editor. Patches should be submitted to the [10]gstreamer-devel mailing list.

[linux-audio-announce] ANNOUNCE: Rosegarden-4-0.8 released

by Richard Bown

The Rosegarden development team would like to announce the release of Rosegarden-4-0.8(*) for immediate download. Please go to the project homepage for further details: http://www.all-day-breakfast.com/rosegarden We'll be demoing Rosegarden at the Linux Expo in Olympia, London, UK, 9th-10th October 2002. Come and see us there. Major features of this release include: - Improved Notation Printing (draft quality) - realtime LADSPA plugin support (chainable plugins for each Instrument) - Note entry using the PC keyboard in notation view - Major Matrix view improvements (zooming, snapgrid size, quantizing) - Major Performance improvements in sequencer - "Stuck notes" problem fixed - Matrix velocity setting dialog - Segment positioning guides - Turn repeating Segments to real copies - Matrix view auto scrolling - Rudimentary lyric editor - Chorus, Reverb, Resonance, Filter, Attack, Release MIDI controls - Specialised Rotary Control widget - Repeating Segments work to end of Composition marker - Composition Start and End Markers can be changed - Splitting Segments fixed - Audio volume faders - EventList editor extended - Better Audio Waveform Previews - SysEx, Program Changes, Controller Changes, PitchBend all supported and editeable at Composition level - Toolbars & Settings saving fixed - Some new useful keyboard shortcuts - Optional Transport toolbars - More preference settings - A couple of new note transformation functions - Some fixes to progress reporting - More help text for Notation * - We've adopted a new numbering scheme for tarballs and packages that will hopefully make things less confusing in the long term. We've also jumped several release numbers for this release in an effort to make things more confusing in the short term. This release is Version 4, Release 0.8 : rosegarden-4-0.8.tar.gz Last release was Version 4, Release 0.2 : rosegarden-0.2.tar.gz

[linux-audio-announce] Mammut V0.10

by Kjetil S. Matheussen

Mammut will FFT your sound in one single gigantic analysis (no windows). These spectral data, where the development in time is incorporated in mysterious ways, may then be transformed by different algorithms prior to resynthesis. An interesting aspect of Mammut is its completely non-intuitive sound transformation approach. New in V0.08 -> 0.10 -Using gtk instead of motif. The reason is cleaner code because of better python-support, and more portable. -Buttons in the main-window. -Support for 16,24 and 32 bits soundfiles, not only 16 bits. -Support for float and double soundfiles. -Fixed filenamebugs in combsplit and reimsplit -Replaced libaudiofile with libsndfile. -Removed soundfile length limitation. -Removed some warnings. -Playing internally from program using sndlib. -Added undo/redo. (currently hardcoded to 300000 levels) http://www.notam02.no/arkiv/src/ Mammut is developed at Notam/Oslo, http://www.notam02.no --

[linux-audio-announce] Announcement: Frequency domain audio analysis tools

by Silvia.Pfeiffer＠csiro.au

We have recently ported our frequency-domain audio analysis library Maaate to the Windows platform and fixed some minor bugs and compile warnings. This is the announcement of Maaate Version 0.3.0 available for Linux, Windows and Solaris. (It uses bewdy 0.2.2 for visualisation under Linux only.) http://www.cmis.csiro.au/maaate/ Maaate: ======= Maaate is a C++ frequency domain audio analysis toolkit. http://www.cmis.csiro.au/maaate/docs/index.html Maaate is a set of libraries supporting frequency-domain based feature analysis. Although it currently only works on MPEG compressed audio files in the compressed domain, the interface to plug-in other file formats (uncompressed or compressed) exists. Maaate also contains some 30 audio feature extraction, segmentation and classification algorithms. It's all published under the GNU GPL. Download it from: http://www.cmis.csiro.au/maaate/docs/download.html Highlights of Maaate version 0.3.0: - a generic frequency-domain based analysis framework - a specific MPEG compressed (frequency) domain analysis library - 30 analysis modules covering * energy features (usable for loudness statistics), * bandwidth features (usable for speech/music segmentation), * spectral statistics (usable for sound type distinction), * silence statistics (usable for speech/music segmentation), * noise features (usable for explosion or crowd cheer detection), * generic segmentation algorithms (thresholds on features) and * some generic statistical algorithms (histogram, variance). - extensive documentation on all modules is also available online (http://www.cmis.csiro.au/maaate/docs/modules.html) - works under Linux, Windows and Solaris Bewdy : ======= Play around with the compressed audio content of MP3 files under Linux! http://www.cmis.csiro.au/maaate/bewdy/index.html Bewdy is a program to visualise frequency domain audio feature analysis and segmentation algorithms. For example, it can display the spectral content of an MPEG audio file in the compressed domain and allows you to play around with analysis algorithms on that data. It uses the (MPEG) Maaate libraries for that purpose and can thus load up any analysis module that is implemented for Maaate. The pictures at http://www.cmis.csiro.au/maaate/snapshots.html and at http://www.cmis.csiro.au/maaate/bewdy/docs/handbook.html show off more of bewdy. Download bewdy from: http://www.cmis.csiro.au/maaate/bewdy/index.html Download Maaate from: http://www.cmis.csiro.au/maaate/docs/download.html About CSIRO audio analysis research: ==================================== Here at CSIRO, an Australian government research organisation, we perform research into the analysis of music and sound. We create software to unravel the structure and texture of recorded audio, and we develop systems which make use of the information extracted. Examples of such systems include searching for music features and indexing soundtracks. Much of our work is available as open source software.
