Unfortunately the faust-0.9.9.4.tar.gz initially uploaded to sourceforge was outdated. it should *not* be used. A new up to date version, named faust-0.9.9.4b.tar.gz, has been uploaded in replacement of the previous one.So please make sure that you are using the new faust-0.9.9.4b.tar.gz. Sorry for the inconvenience ! Yann

Thanks Kjetil for pointing the problem. It seems that the tar.gz that I have uploaded is not the correct one ! It is not in sync with the cvs. I am investigating... Yann Kjetil S.

[ANN] Faust 0.9.9.4

by Yann Orlarey

Grame - Centre National de Creation Musicale - is pleased to announce the release of Faust 0.9.9.4. Faust AUdio STreams is a powerful and expressive functional programming language for realtime audio signal processing. The Faust compiler translates DSP specifications into efficient C++ code. A variety of platforms and plugin formats are supported. A single Faust specification can be used to easily generate JACK and ALSA applications, as well as LADSPA, MAX/MSP, PD, Q, SC and VST plugins. In addition to C++ code, the Faust compiler can also generate SVG block-diagram representations as well as XML descriptions. To easily test Faust before installing it, please refer to http://faust.grame.fr. The Faust distribution can be downloaded at http://sourceforge.net/projects/faudiostream. Debian and rpm packages are also available from Debian, Ubuntu, Planetccrma and Packman. Please note that Faust can now also be used from within the CLAM 1.2 audio and music application development framework (http://clam.iua.upf.edu/) and the Snd-rt 0.8.9.13 realtime music programming environment (http://www.notam02.no/arkiv/doc/snd-rt) ------------ What's new : ------------ * Syntax modification allowing unary operator - with identifiers (-x is now allowed) * Parametric string can now contain the number of digits to use. In the string "line %2i" %2i will be replaced by the value of i using at least 2 digits. * New fvariable declaration : possibility to declare an external C variable of block variability. * Redefinition of symbols is now considered an error instead of a simple warning * New syntax highlighting for TextWrangler (Macintosh) * snd-rt-gtk.cpp: a new architecture file to use Faust with snd-rt. (Contributed by Kjetil Matheussen) * synthfile.cpp: a new architecture file to generate audio files (contributed by Dominique Fober) * osc.lib: a new oscillator library containing fast filter-based oscillators (contributed by Julius Smith) ----------------- What's improved : ----------------- * new additions to filter.lib and effect.lib : Piano dispersion filter, fifth-order fdelay5, notch filter, Second order transformer-normalized digital waveguide resonator... (contributed by Julius Smith) * Improved jack-gtk.cpp architecture file allowing to control the default connexions and to run several instances of the same program (contributed by Fons Adriaensen) * Huge speedup of type inference system for complex expressions by using memoization and recursiveness information ------------ Bugs fixed : ------------ * Bug correction in the type inference system of recursive expressions * Better sharing of slow expressions appearing delayed * Avoid division by zero and report error when block-diagrams with no inputs or outputs are used in merge and split compositions * The Faust compiler and some of the architecture files have been updated to replace char* parameters by const char* when appropriate --------------- Acknowledgments --------------- We are grateful to Fons Adriaensen, Dominique Fober, Albert Graef, Kjetil Matheussen, Julius Smith and all the contributors of this new release. Keep sending us remarks, suggestions, bug reports and contributions.

Call for Student Participation - CLAM in Google Summer of Code 2008

by Pau Arumí

We are glad to announce that 2008 summer is also going to be a Summer of Code for CLAM [1]. In other words, CLAM has been accepted as a mentoring organization for the Google Summer of Code, a program that offers student developers stipends of 4500 USD to write code for open source projects [2]. We are looking for smart students who enjoy coding free software so that they can earn some bucks for the summer. Last year, GSoC 2007[3] was a very fun and productive experience and we are willing to repeat it. Take a look at the CLAM GSoC 2008 wiki page[4] for more information on how to apply and some sample ideas[5] for projects. CLAM (C++ Library for Audio and Music) is a framework for research and applications development in the audio domain. It offers a multi-rate dataflow model suited for spectral processing, and a visual building tool that allows to develop rapid prototypes without writing code. See the CLAM web for more details and screenshots. We are waiting for you! Application deadline: March 31 If you have any question about any of the information below please contact ask to clam-devel list or join the #clam channel at FreeNode IRC.

[ANN] Qtractor 0.1.2 (frantic dame) is out!

by Rui Nuno Capela

Season greetings, As (almost) everybody knows already, or ought to, Qtractor is an Audio/MIDI multi-track sequencer application, written in C++ on the Qt4 framework and Linux is about its native platform. Thus, JACK and ALSA are the main infrastructures that fit to purpose, respectively for audio and MIDI. Also a known fact is that this is nothing more than my pet, hobby, spare-time-burner, whatever project, but... it's actually my own dogfood where digital music making and (re)creation matters. Yep. I still have this sublime hope to make it evolve as a fairly featured Desktop Audio/MIDI Workstation, one special and dedicated to the personal homestudio. As joked many times before, it's perfectly tagged for the techno-boy bedroom home-studio, but techno-girls can also apply ;). You tell me. Qtractor 0.1.2 (frantic dame) is out! As obvious as in any respectable easter egg ;) This time, some important fixes have sneaked in and other are surely popping and will be lurking out. Main ones go down like this: * You can finally create new clips from scratch. * Track record monitoring with audio effects applied. * New Track/View menu items, all shortcut configurable. * Overlapped clips rendering hopefully fixed. * Improved MIDI editor selection. * New clip-split command. * VST plug-in parameters are now undo/redo-able (mostly). You can grab the new stuff from the usual project site: http://qtractor.sourceforge.net http://sourceforge.net/projects/qtractor Direct download links: http://downloads.sourceforge.net/qtractor/qtractor-0.1.2.tar.gz http://downloads.sourceforge.net/qtractor/qtractor-0.1.2-user-manual.pdf Wait, please take a note: if you ever feel you're having something to say, a heads-up call or just a direction to point, do not ever hesitate in having your worries known upstream. Please, feel welcome at my http://www.rncbc.org Now the plain change-log follows, since she was just a futile duchess: - Session length fixed (yet again) while extend recording; also improved follow-playhead switching while playback/recording. - Whitespace sanitization gets leaner for all recorded filenames. - Run-time SSE optimization detection has been improved while on configure; additionally, IEEE 32bit float specific optimizations have also sneaked in. - SSE optimization is now featured over all audio monitoring, and most specially on audio bus buffering, lowering the CPU burden a bit while doing track and bus gain, pan, metering and mix-down. - Fixed MIDI clip move into new track, preserving the original channel, bank and program whenever possible. - Fixed session cursor seeking, specially regarding overlapped clips, once gain. - The MIDI editor gets new menu access to current MIDI clip track (see File/Track/Inputs, Outputs, Properties); selection of MIDI events has also been improved, specially regarding overlapped note events. - Clip split command enters the stage (see Edit/Clip/Split) about splitting the current (selected) clip at the current playhead position (red cursor line). - Creating new clips from scratch is now finally permitted (see Edit/Clip/New...); additionally, the clip properties dialog is now also allowing for changing the filename (and track/channel as special to MIDI clips). - Record armed tracks are now properly monitored and fed through their own output audio bus on mix-down, which includes plug-in effects processing. - The files widget get alternating coloured rows. - VST plug-in preset values are now being restored properly; individual parameter changes are now being queued for the also convenient undo/redo command pattern. - Some audio clip buffer-sync tweaks have sneaked in, improving and fixing the rendering of full-overlapped, integrally cached and/or offset clips altogether. - Stuffed one primordial shot on XInitThreads() at the main head, and let native VST plug-ins start behaving as they should, or not; this might be in fact problematic and dangerous for people who won't ever try the JUCE based plugins as from JUCETICE (http://www.anticore.org/jucetice), due to some broken locking mechanism in xcb; thanks anyway to mighty kRAkEn/gORe@JUCETICE for this precious hint and from who knows best. - True deterministic session length update has due fixed. - Track menu has new accessible actions: Track/Inputs - show current track input bus connections; Track/Outputs - show current track output bus connections; Track/State/Record - arm current track for recording; Track/State/Mute - mute current track; Track/State/Solo - solo current track; Track/Navigate/First - make current the first track; Track/Navigate/Previous - make current the previous track; Track/Navigate/Next - make current the next track; Track/Navigate/Last - make current the last track; Track/Move/Top - move current track to top; Track/Move/Up - move current track up; Track/Move/Down - move current track down; Track/Move/Bottom - move current track to bottom; - View menus have new accessible actions: View/Zoom/In - horizontal and vertical zoom-in (Ctrl +); View/Zoom/Out - horizontal and vertical zoom-out (Ctrl -); View/Zoom/Reset - reset both zoom levels to default; View/Snap - select current snap-per-beat setting; - Plug-in forms don't auto-open on session reload anymore. - Keyboard shortcuts icon item (Help/Shortcuts...) sneaks in. That's all folks. For the time being... :) Cheers && Enjoy -- rncbc aka Rui Nuno Capela

[ANN] Snd-Rt homepage update, Snd-ls V0.9.8.13 and jack_capture V0.9.7

by Kjetil S. Matheussen

Snd-Rt ====== Snd-rt is a realtime music programming environment running inside the Snd sound editor. The homepage has been updated with links, papers and many examples on how to create GUI's and how to access Faust. The old fancy design is still kept unchanged. http://www.notam02.no/arkiv/doc/snd-rt/ Snd-ls V0.9.8.13 ================ 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) http://www.notam02.no/arkiv/src/snd/ Changes 0.9.8.5 -> 0.9.8.13 --------------------------- -Updated Snd-Rt. (unguote-splicing, gui) -Updated Snd-Rt. (gui, dynamic scoping, oscil* etc.) -Updated Snd-Rt. (timer) -Updated Snd-Rt. (timer, faust, definstrument) -Updated Snd-Rt. Faust support. -Fixed rt timer. Previously it only ran 3 hours before giving negative numbers. Now it should run approx. 13 million years. (not tested) -Removed access to removed functions in jack. -Updated eval-c.scm. 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...) http://www.notam02.no/arkiv/src/ 0.9.6 -> 0.9.7: *Don't segfault if the opening of a subsequent wav soundfile fails. (ie. if the 4GB limitation is reached on the old file and jack_capture continues writing on a new file.)
