Hi list, I'm happy to announce the release of Spek 0.6 - a multi-platform acoustic spectrum analyser. Spek is available on GNU/Linux, Windows and Mac OS X. Find out more about Spek on its website: http://www.spek-project.org/ New Features And Enhancements: Spek 0.6 is part of beta 0.x releases, leading up to a stable 1.0 release later this year. Check Spek website for the roadmap. New features since 0.5: * Switch from GStreamer to FFmpeg libraries for audio decoding. This speeds up the overall analysis by a factor of 1.5 to 2. * Decode audio and perform the analysis in separate threads. This makes the analysis 1.3~1.8 times faster on multi-core systems (issue 11). * Check for a new version once a week and notify when it becomes available (issue 27) Enhancements: * Windows installer branding (issue 32) * Option to launch Spek when the Windows installer exits Bugfixes: * Fix link activation on Windows (issue 31) * Fix ALAC issues on OS X (issue 23) * Re-run the analysis only if the window width has been changed * Fix opening of files containing Unicode symbols in their name on Windows Cheers, Alex

StretchPlayer 0.502: Real-time audio player with time stretch

by Gabriel M. Beddingfield

I am pleased to release StrechPlayer 0.502, a time-stretching, pitch-shifting audio file player. It is powered by librubberband, and also features an A/B repeat. NEW IN THIS RELEASE ------------------- * Reduced Xorg load (was typ. 20-30% CPU even when idle) * Fix build errors on 64-bit systems (incompatible integer types). * Add CMake USE_COMPOSITING option to explicitly disable compositing features. LINKS ----- Home Page: http://www.teuton.org/~gabriel/stretchplayer/ Tarball: http://www.teuton.org/~gabriel/stretchplayer/stretchplayer_0.502.tar.gz Binary: Ubuntu/Karmic http://www.teuton.org/~gabriel/stretchplayer/stretchplayer_0.502_karmic_i38… http://www.teuton.org/~gabriel/stretchplayer/stretchplayer-dbg_0.502_karmic… Debian Dsc: http://www.teuton.org/~gabriel/stretchplayer/stretchplayer_0.502.dsc Git: http://gitorious.org/stretchplayer git://gitorious.org/stretchplayer/stretchplayer.git USING THE PROGRAM ----------------- After stretchplayer is installed, there should be an [S] icon under Multimedia or Sound. Or, you can run it from the command line like this: $ stretchplayer The GUI is pretty self-explanatory, and if you hover over the controls a tool-tip should appear. The GUI also has several keyboard accelerators. To play a file, click the file-open icon and select an audio file. Stretchplayer can play anything that libsndfile supports (ogg, flac, wav, etc.). However, it does /not/ support MP3 files at this time. As the file plays, slide the horizontal slider left or right to change the speed of the song. If you wish to transpose the audio, push one of the + or - buttons. INSTALLING THE PROGRAM ---------------------- You will need at least a 1200 MHz processor[1] to use this program. It also requires the following libraries: * Qt >= 4.4 http://qt.nokia.com * librubberband http://www.breakfastquay.com/rubberband/ * libsndfile http://www.mega-nerd.com/libsndfile/ * JACK http://jackaudio.org/ * CMake http://www.cmake.org/ If you are running Ubuntu Karmic or Ubuntu Jaunty, you can install the .deb packages like this (from the command line): $ sudo dpkg -i stretchplayer*_0.502_karmic_i386.deb Anyone else will need to build from source. Please read the INSTALL.txt file that comes with the taarball. Peace, Gabriel M. Beddingfield 2010-07-11 [1] With this release, Stretchplayer works OK (but not great) with an 800MHz Celeron processor. Before this release, it was unusable on this system.

[ANN] guitarix-0.10.0 released

by hermann

guitarix is a simple Linux Rock Guitar amplifier and is designed to achieve nice thrash/metal/rock/blues guitar sounds. guitarix uses the Jack Audio Connection Kit as its audio backend and brings to the jack audio graph a mono amplifier input/output port, and a FX mono input with two (stereo) output ports. guitarix provide a jack midi input port to connect a midi controller (midi learn) and a (3 channel) jack midi output port, feed by a (scalable) mix of the tuner and a beat-detector. Release 0.10.0 comes with following changes : * add tonestack models * add 2. amp model * add cabinet impulse response module * add Patch Info widget * add Preset File Load/Export option * add simple looper * add Oscilloscope and tuner state to main settings * selectable distortion model (multi/single line) * selectable EQ model (fixed/scalable freq) * free mem when not used (delay lines) * reworked Gui * fix various bugs have fun _________________________________________________________________________ Note:// for experienced Users there is a Experimental widget witch comes with the tremolo effect contributed by transmogrifox (Rakarrack dev-team) please look ./waf --help for how to build with this widget activated. Many thanks to transmogrifox for his contribution. _________________________________________________________________________ guitarix is licensed under the GPL. Project page with screenshots: http://guitarix.sourceforge.net/ download: http://sourceforge.net/projects/guitarix/ please report bugs and suggestions in our forum here: http://sourceforge.net/apps/phpbb/guitarix/ ________________________________________________________________________ For capture, guitarix uses the great 'jack_capture' (version >= 0.9.30) written by Kjetil S. Matheussen. If you don't have it installed, you can look here: http://old.notam02.no/arkiv/src/?M=D For extra Impulse Responses, guitarix uses the zita-convolver library, and, for up/down sampling we use zita-resampler, both written by Fons Adriaensen. If you don't have it installed, get it here: http://www.kokkinizita.net/linuxaudio/index.html We use the marvellous faust compiler to build the amp and effects and will say thanks to : Julius Smith http://ccrma.stanford.edu/realsimple/faust/ : Albert Graef http://q-lang.sourceforge.net/examples.html#Faust : Yann Orlary http://faust.grame.fr/ ________________________________________________________________________ For faust users : All used Faust dsp files are included in /guitarix/src/faust, the resulting cc files are in /guitarix/src/faust-cc The tools we use to convert (post-processing and plot) the resulting faust cpp files to the needed include format, stay in the /guitarix/tools directory. ________________________________________________________________________ regards Hermann Meyer, James Warden, Andreas Degert

[ANN] Drumstick 0.4.0 released

by Pedro Lopez-Cabanillas

Drumstick is a C++ wrapper around the ALSA library sequencer interface using Qt4 objects, idioms and style. ALSA sequencer provides software support for MIDI technology on Linux. Complementary classes for SMF and WRK file processing are also included. This library is used in KMetronome, KMidimon and KMid2, and was formerly known as "aseqmm". Changes: * New visibility attribute for all public classes allowing client programs to be compiled with hidden visibility if desired. * Better error reporting for all the utilities. * Subdirectory "tests" renamed as "utils". * Utility "smfplayer" renamed as "guiplayer" and enhanced with a new interface design and support for Cakewalk WRK files.

gst123-0.1.2

by Stefan Westerfeld

gst123-0.1.2 has been released. Overview of changes in gst123-0.1.2: ------------------------------------ * Added -a option to select audio driver (oss, alsa) and device (/dev/dsp1, hw:1) * Fix crash triggered when closing the video window (thanks Siddhesh Poyarekar) * Improved configure check (works now if ncurses headers are not in /usr/include) What is gst123? --------------- The program gst123 is designed to be a more flexible command line player in the spirit of ogg123 and mpg123, based on gstreamer. It plays all file formats gstreamer understands, so if you have a music collection which contains different file formats, like flac, ogg and mp3, you can use gst123 to play all your music files. Since gst123-0.1.0 support for watching videos has been added; however gst123 should run fine in situations where no X11 display is available; videos can be played without X11 display, too (-x, --novideo); in this case, only the audio stream will be played. It is implemented in C++ and licensed under the GNU LGPL version 2 Links: ------ Website: http://space.twc.de/~stefan/gst123.php Download: http://space.twc.de/~stefan/gst123/gst123-0.1.2.tar.bz2 -- Stefan Westerfeld, Hamburg/Germany, http://space.twc.de/~stefan

spectmorph-0.0.3

by Stefan Westerfeld

spectmorph-0.0.3 has been released. The main improvement is that the piano samples sound a lot better now, because the attack is modelled better by the SpectMorph model. Overview of Changes in spectmorph-0.0.3: ---------------------------------------- * added encoder algorithm to find attack envelope, this makes piano sound much more realistic * introduced smwavset tool, which allows managing instruments consisting of many samples - encoding/decoding a set of samples - delta operation for comparing errors of sets of samples * smextract can now provide an overview of how many bytes in an .sm file can be attributed to which fields * documentation updates * refactoring, cleanups What is SpectMorph? ------------------- SpectMorph is a free software project which allows to analyze samples of musical instruments. This should allow constructing hybrid sounds, for instance a sound between a trumpet and a flute. Also interpolating between two samples of the same instrument (different attack velocity of a piano) could be interesting. SpectMorph is implemented in C++ and licensed under the GNU LGPL version 3 SpectMorph currently is in the early stages of development, which means that it is not yet ready to be used by end users. Links: ------ Website: http://space.twc.de/~stefan/spectmorph.php Download: http://space.twc.de/~stefan/spectmorph/spectmorph-0.0.3.tar.bz2 There are sound examples on the website which demonstrate the sound quality of the current SpectMorph models using piano samples. -- Stefan Westerfeld, Hamburg/Germany, http://space.twc.de/~stefan
