As happens all too often, its been longer than expected between releases, but finally Ardour 2.5 is ready to ease the path, soothe the brow and excite the heart of musicians and audio engineers worldwide. Tons of bug fixes and several new features will make it worthwhile for everyone and anyone to try this out. http://ardour.org/download Note that you should probably remove ~/.ardour2/ardour.bindings in order to ensure that you get the latest key bindings. As noted below, this file will no longer be created unless you explicitly edit the key bindings yourself via the GUI. PACKAGERS and SOURCE BUILDERS please note that this release sees a new library dependency. Ardour 2.5 requires the aubio library, which is small and fast to build. Many distributions do not currently package it. You know what to do ... OS X users The first native release of 2.5 will not be ready until at the earliest July 13th, possibly as much as several days after that. We apologize for the delay, caused by problems with our build system. New Features ============= * plugin selection via menu (per plugin "manufacturer") * plugin "favorites" * dynamic track resizing with the mouse * Rhythm Ferret now has note onset detection as an alternative to percussion onsets. * make track faders display automation-driven changes * add "Consolidate Range" which writes a new audio file and uses it to replace whatever was in the playlist within the range * add "make range to next marker" and "export range" context menu items for range markers * all GUI menu items/actions can now be activated using OSC * new "name-new-markers-at-creation" option * zoom-to-region (on one or both axes) * fit-tracks (selected tracks sized to vertically fill editor window) * insert-time operation to add "silence" to the timeline * 12 saved "view states" that save zoom levels and timeline positions * working latency compensation and I/O configuration for AU plugins * goto-wall-clock command * * Fixes and Improvements ====================== * at least 20 crashing bugs fixed * use latest version of libsigc++ (potential bug fixes) * use version 1.2 of RubberBand for speed & quality improvements and potential patent avoidance * online (and available) manual updated, including correct key binding tables * editor GUI is now 100% 64-bit for audio timeline values * never save keybindings to user's ardour directory unless they change them * allow keybindings to use arrow keys (GTK doesn't permit this) * fix for plugins-do-not-work-on-all-channels bug * fix track selection sensitivity botch for Import action, should have been toggle-waveform-visible instead * Support FFT for multi channel tracks and fix analysis for tape track regions. * fix mix group problems caused by recursive loop when modifying gain/gui * make big clock stay on top even in broken desktop environments * fixes to correct the results of running time/pitch shifting multiple times on the same region * updated swedish translation * don't double-call JackStartFreewheeling if we're already freewheeling * small changes to export code to hopefully fix some bugs with range export(s) * minor UI fixes for clocks and Locations dialog. Prevent tape tracks from skewing the session extents * major fix for computing plugin I/O configuration when using mono/stereo plugins in stereo/mono tracks/busses * fix up scaling problems with cleanup caused by redisplaying all regions every time a file is removed * fix for illegal audio device selection in audio setup dialog * fix for plugins being shown twice in the automation menus * make generation of new region names scale properly rather than being O(N^2) * reset meter peaks when meter point is reset * editor faders now insensitive to unmodified scroll wheel events (Alt-scroll does the same thing) * change the step size for scroll-driven resizing * make region context menu items always operate on well-defined and reasonably obvious region selection * ctrl-w shortcut ("close dialog") works on plugin editors * make bounce range and bounce region work properly (wrong boundaries before) * prevent periodic auto-save from causing GUI deadlock during export-ranges * improve horizontal scrolling. When the playhead is moved past the end marker, the canvas will alter its boundaries as needed. The Zoom to Session button will now reset the canvas size to start-2-end plus a little extra after end, so the end marker is visible. * Move the Enable Track Meters option to Metering menu section * removing sends now cleans up fully, preventing problems when adding sends again later * check both whole-file and part-file regions when adding to the visible region list, and do not show regions that are region list equivalent with existing entries * Fix up checks for whether the track height is too small for the name highlight. Fixes irritating issue with 31 pixel height tracks having small waveforms but no name highlight. * make "feature lines" always be the right height as tracks resize * nudge clock now has a default value of 5 seconds, not zero * What used to be the pink recording rectangle is now blended into the recording regions so that they appear to be the same thing. Then recording specific colors are added so the waveform and region base when recording are all various shades of red during recording. *** Open Theme Manager and click Restore Defaults for these changes to apply *** Contributors ============ Paul Davis, Ben Loftis, Doug Mclain, Ryan Scott, Colin Fletcher, Sampo Savolainen, Jesse Chappell, Sakari Bergen, Dominic Sacre

Qsynth 0.3.3 Knobs Galore!

by Rui Nuno Capela

Greetings, Thanks to Pedro Lopez-Cabanillas and Guido Scholz, this Qsynth release is now a reality. Main new features are a the new rotating knob style options, first full translations, German and Spanish and last but not least, there's this Windows(TM) all-in-one package available (includes FluidSynth port) for your (sick:) pleasure only. Please read below the brilliant notes from Pedro about this breakthrouth release. Yes, before's too late: Qsynth</a> 0.3.3 (unstable-qt4) is out! For the clueless, Qsynth is a Qt GUI frontend application to the excellent FluidSynth (http://www.fluidsynth.org) soft-synth library implementation for the SoundFont 2 specifications. Available from the usual place: http://qsynth.sourceforge.net http://sourceforge.net/projects/qsynth There's the change log for this point release: - Due to some trouble with newer Qt >= 4.4 applications regarding font size configuration, a new global user option is now available to the rescue: Options.../Other/Base font size (default is no-op). - Knobs: graphic styles are now QStyle derived classes, which are assigned to the knobs using QWidget::setStyle(). Three styles are implemented in this way, supporting also the legacy QDial: * Our former look, tweaked and ported from Sonic Visualizer. * A port of the new look implemented by David Garcia. * Another ported widget style, designed by Giuseppe Cigala. - Spanish translation added. - Attempt to load Qt's own translation support and get rid of the ever warning startup message, unless built in debug moderr; also introducing the very first and complete German translation (patching transaction by Guido Scholz, thanks). - Messages file logging makes its first long overdue appearance, with user configurable settings in Options/Logging. - Only one application instance is now allowed to be up and running, with immediate but graceful termination upon startup iif an already running instance is detected, which will see its main widget shown up and all engines started automatically (Qt/X11 platform only).</li> Notes about the Windows(TM) package: (http://downloads.sourceforge.net/qsynth/qsynth-0.3.3-setup.exe) * It is a bundle of Fluidsynth 1.0.8 (patched) and QSynth 0.3.3, compiled in Windows with MinGW 3.4.2 and Qt 4.4.0. The package includes all the required libraries except DirectX-9, which should be installed before. The setup program itself was created with NSIS 2.37 (http://nsis.sf.net) * The patch for Fluidsynth (attached) was needed to allow QSynth to specify the name of a MIDI port to be opened other than the first one. The patch was sent to the Fluid-dev mailing list, but maybe we could offer it also in the QSynth web site? Link to the mailing list message: http://www.mail-archive.com/fluid-dev@nongnu.org/msg00816.html * Users should not expect the same functionality level in Windows compared to the Linux version. In windows it is not possible to connect the MIDI out from one program to the MIDI input of another application. QSynth/Fluidsynth needs to read MIDI events from a real MIDI device, as a keyboard. For something similar to the ALSA sequencer routing capabilities, you can try MIDIOX/MIDIYoke (http://midiox.com) Cheers && Enjoy -- rncbc aka Rui Nuno Capela

[ANN] Sonic Visualiser v1.3 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 1.3 of Sonic Visualiser is now available. http://www.sonicvisualiser.org/ This is a feature release, containing several new features and a number of bug fixes over the previous 1.2 release. For more details, please read the release notes at http://sourceforge.net/project/shownotes.php?release_id=612594 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/ Sonic Visualiser is Free Software distributed under the GNU General Public License. The 1.3 release is available now in source code form or as binaries for Linux, OS/X, and Windows. Chris

[ANN] Vamp plugin SDK v1.3 now available

by Chris Cannam

Version 1.3 of the Vamp plugin SDK is now available. http://www.vamp-plugins.org/ Vamp is a plugin API for audio analysis and feature extraction plugins written in C or C++. Its SDK features an easy-to-use set of C++ classes for plugin and host developers, a reference host implementation, example plugins, and documentation. It is supported across Linux, OS/X and Windows. Version 1.3 is a maintenance release, with several bugfixes (almost all of which only affect hosts, not plugins) and no new features. Changes since 1.2: * PluginBufferingAdapter has several important fixes to bugs that could cause incorrect timings or output descriptors to be returned * Conversion between real-time and frames has been improved to avoid rounding error in round-trip calculations * Plugin lookup no longer relies on non-portable DT_REG * The SDK now compiles with gcc 4.3 (knowing my luck it probably won't, but it's supposed to) Plugins and hosts remain binary compatible with those built using the 1.0 version of the SDK.

[ANN] jack_capture V0.9.19, Snd-ls V0.9.8.17 and Rollendurcmesserzeitsammler V0.0.4

by Kjetil S. Matheussen

Download from: http://old.notam02.no/arkiv/src/?M=D jack_capture ============ jack_capture is a program for recording soundfiles with jack. Its default operation is to capture whatever sound is going out to your speakers into a file. (But it can do a number of other operations as well...) Changes 0.9.17 -> 0.9.19: *Do not accept filename starting with "-" when filename is last argument. *Added the "--filename"/"-fn" option to set filename not as the last argument. Can also contain "-" as first character. *Fixed colors a bit and removed a superfluous linebreak. *Fixed segfault for missing values in commandline. *Manually clear allocated memory instead of using calloc. *Removed buffer-info line when recording to stdout. *Removed printing of "continue recording" when writing the last overruns. *Niceify the disk writing thread to -20 when more than half the buffer is used. *Continously show buffer usage, total number of overruns and whether the disk thread has high priority, in the console. Turn off by using the -hdu option. *Added option -dc to disable console update. (same as "-dm -hdu") *Fancier colors. *Removed "hepp". *Made dB meter the default and replaced the -dB option with the -lm option. *Made the console meter wider to fit the info line at the bottom. Snd-ls ====== Snd-ls is a distribution of Bill Schottstaedt's sound editor SND. (http://ccrma.stanford.edu/software/snd/) Its target is people that don't know scheme very well, and don't want to spend too much time configuring Snd. It can also serve as a quick introduction to Snd and how it can be set up. Snd-ls also serves as base code for the San-Dysth softsynth (http://www.notam02.no/~kjetism/sandysth/) and the Snd-rt music programming language (http://www.notam02.no/arkiv/doc/snd-rt) Changes 0.9.8.16 -> 0.9.8.17: *(read-enable 'positions) has been wrongfully turned off for some time. Bactrace should work again now. (This only affects people using snd-ls for programming.) Rollendurchmesserzeitsammler ============================ The Audio Rollendurchmesserzeitsammler is a conservative garbage collector providing general ways to efficiently allocate and use memory inside a realtime audio thread without having to manually free it later. Changes 0.0.1 -> 0.0.4 * Added support for iterior pointers. (Pointers which points inside middle of allocated memory). Turned out Stalin depended on this, plus that c compiler are free to store pointers in registers and stack however they want, so it's better to be safe. * Fixed header. * Made it packagable. Write make and make install to install library file and header files. * Added the function tar_get_dynamic_roots_for(char *pointer,char **start,char **end). This function requires the source for HBGC: http://www.hpl.hp.com/personal/Hans_Boehm/gc/ * Note that there are ways to increase the execution speed significantly, I just haven't had the time yet, so this update doesn't contain all the changes I wished for.
