(i had no creative input at all, i just made Thorsten's mesh move) blender creates a sequence of knob sized frames (with an alpha channel, should that be desired) then, the image magick tool "convert" is used (eg "convert +append output.png *.png" to concatenate the frames into a large single image which can be easily loaded and manipulated programatically. (as is done in the phat knob and numerous other pixmap knobs derived from the galan C code) the method is independent of the code you use so there's no reason why it shouldn't be useful to you. in fact, it's so simple that i've duplicated your red knob design. see here for the blender (.blend) file: http://www.zenadsl6252.zen.co.uk/flat-red-100-frames.blend and here for the output: http://www.zenadsl6252.zen.co.uk/flat-red-100-frames.png it's trivial to change the number of frames, the colours used or the frame size and re-render it. you can also adjust the output filter to sharpen or soften the edges. i must admit though, that with a minimal design like this, you might do well to implement it algorithmically with drawing operations. then you can make run time changes to the appearance. if you want something more complex or tactile then you could use Thorsten's knob animation or give me a shout and i'll knock something out to your specs. (although, bear in mind that my blender skills are somewhat limited so it won't be a work of art =) pete.

Source code for Open Sound System now available under GPLv2 and CDDL 1.0

by Hannu Savolainen

Hi folks, Now it has happened. Open Sound System is finally open sourced. Source downloads are available from http://developer.opensound.com/sources The actual announcement follows. Best regards, Hannu ------------------------------------------------------------------ FOR IMMEDIATE RELEASE 4FRONT TECHNOLOGIES RELEASES THE SOURCE CODE FOR OPEN SOUND SYSTEM CULVER CITY, CA, June 14, 2007: 4Front Technologies is proud to announce the release of the source code to Open Sound System (OSS) v4.0. The software currently runs on Linux, Solaris™, SCO UnixWare™ and FreeBSD platforms. OSS is a cross platform API that provides drivers for most consumer and professional audio devices for UNIX® and POSIX based operating systems, including Linux. Owing to its open architecture, applications developed on one supporting operating system platform can be easily recompiled on any other platform. Licensing Models: Open Sound System source code is now available under 3 licenses: · GNU Public License (GPL) version 2 · Common Development and Distribution License (CDDL) for all operating systems that have full source code available under the BSD or CDDL licenses. · 4Front’s commercial license for using Open Sound incompatible with open source licenses listed above. Commercial licenses are also available for entities not wishing to use Open Sound System under any of the above open source licenses What is being open sourced? The source code includes drivers for most consumer PCI and USB audio devices and operating system support, including binary package generation and sample test programs. Complete documentation and API specification is also being made available to the open source community. A device driver kit (DDK) is also available for developers to implement cross platform device drivers for audio hardware. This eliminates lot of redundant work that has traditionally been required to support any hardware under multiple Unix/POSIX operating systems. Reasons for going Open Source: OSS has been an open API specification with multiple implementations by independent developer communities. This has caused problems for application designers because there are minor differences between the implementations. The new open source community development model makes it possible to replace the obsolete and incompatible vendor specific sound subsystems and OSS implementations with a state-of-the-art implementation developed by 4Front Technologies. The goal has always been to standardize audio under POSIX compliant systems and this includes real time operating systems and embedded systems as well. "We are open sourcing OSS because this provides a great opportunity for different communities to work together to provide wider audio hardware support for all operating systems." said Hannu Savolainen, CTO and chief architect of Open Sound System. Industry Reaction: "It's great to see 4Front releasing OSS under the Common Development and Distribution License (CDDL). It's something the OpenSolaris™community welcomes, and it provides an opportunity to improve sound support for all OpenSolaris™ distributions," says Stephen Lau, OpenSolaris™ board member. "Fluendo is excited to see the open source release of 4Front Technologies advanced OSS implementation for UNIX® and Linux. Getting a unified and advanced sound system across all major UNIX® and Linux variants will be a big advantage for developers. We look forward to working together with 4Front Technologies to make sure the GStreamer multimedia framework and the Open Sound System integrates perfectly with each other", says Fluendo Business Development Manager Christian F.K. Schaller. "With a long history of successful collaboration with 4Front, Creative looks forward to working with the Open Sound System community in ensuring that Creative Sound Blaster Live! and Sound Blaster Audigy sound cards have stable and well-supported drivers on Linux, Solaris and BSD. The open source release of Open Sound certainly helps our goal in providing cross-platform support for our products," said George Thorn, director of digital media relations for Creative Labs. Community Portal A new web site with source code, API specs and forums for the developer community has been opened at http://developer.opensound.com <http://developer.opensound.com/>.

[ANN] AlsaPlayer 0.99.80-rc1 and FftScope 1.0.5

by Dominique Michel

I am very proud to announce 2 new releases: alsaplayer-0.99.80-rc1 and fftscope-1.0.5 The main added feature in those 2 packages is a new GTK2 interface. I must thank Madej. He done most of the job and is still working to improve it. Alsaplayer-0.99.80-rc1 ---------------------- AlsaPlayer is a new type of PCM player. It is heavily multi-threaded and tries to excercise the ALSA library and driver quite a bit. It has some very interesting features unique to Linux/Unix players. This is a major feature enhancement release. The player has now a fully working GTK2 interface. It includes the same functionality as the GTK1 interface and some new functions. The playlist window has been completely rewritten and is inside the main window. The scopes plugins have been migrated too. A lot of debugging has been made. Every user is encouraged to upgrade AlsaPlayer and use the GTK2 interface. We need your help with a few things: * Bug reports * Feature requests * Artwork contributions fftscope 1.0.5 -------------- Fftscope is a nice fft scope plugin for Alsaplayer. It is now 2 versions of this scope in the package: one with GTK1 interface, the other with GTK2 interface. This is a major feature enhancement release Enjoy those 2 new releases! --------------------------- http://www.alsaplayer.org/ http://sourceforge.net/project/showfiles.php?group_id=249 Dominique

CLAM 1.1, The `More eye-candy, please' release.

by Pau Arumi

CLAM 1.1, The `More eye-candy, please' release. After a very intense development months since the last 1.0 release, the CLAM crew is glad to announce that CLAM 1.1 is ready to [1]download. It comes with many new features and code clean up. Most important improvements are found in the Visual Prototyping front: new 3D-looking widgets, new data viewers and control surface; and a simplified way to bind controls between the user interface and the processing network. To learn about CLAM: http://clam.iua.upf.edu This release has been cooked-up under the umbrella of the Interactive Technology Group at the UPF lead by Josep Blat. So we thank their support! It also features the work from contributors such as Zach Welch; as well as the first patches from [2]Google Summer of Code program --for example LADSPA and FAUST support and some work on Annotator widgets. A summarized list of changes follows. See also the [3]CHANGES files for details. New audio related widgets were added to be used on the NetworkEditor and the Prototyper. Such widgets include data views such as the BarGraph which can display LPC's, MFCC's. Nice control widgets were also added. The ControlSurface, for instance, to control two scalar parameters by moving a point. Some widgets were gathered from the LAC community, such as [4]PkSampler [5]PovRay generated widgets, and nice knobs we enhanced from [6]QSynth and [7]Rosegarden. Thanks to the developers of those projects for making them GPL and being so supportive while integrating them in CLAM. With all those widgets, users now can visually build more appealing applications such as the new examples we include with Prototyper: A real-time gender change, or real-time spectral effects. The TonalAnalysis (Chord extraction) now takes advantage of fftw3 performing 4 times faster! The KeySpace visualization was also optimized so now tonal analysis runs even on very slow computers. NetworkEditor and Prototyper usability have been enhanced. They exploit the new in-control bounds parameters to automatically set up bounded control senders widgets. Also, NetworkEditor have proper multi-processing selection features. On different fronts, the code-base has been reduced by getting rid of Fltk and Qt3 modules since we are now focusing on Qt4, and the documentation have been restructured and now it offers new programming how-tos.

pipe/cond/semaphore/etc benchmarks

by Dave Robillard

Hi all, I remember a while back someone posting results of a benchmark to compare performance of pipes vs cond vs semaphores, but I can't find the specific post or code in the archives for the life of me. Does anyone have the /code/ for that benchmark (or anything similar I can fiddle with to do some testing)? Thanks, -DR-

pipes or network?

by Malte Steiner

Hello, I wonder what is the best way to connect applications on the same computer. Usually I use network and localhost plus custom protocols or OSC to let them communicate but wonder if pipes are more efficient. The data to be exchanged is usually control rate, not audio nor video streams. So what are the pros and cons of pipes versus network? Cheers, Malte -- Malte Steiner media art + development -www.block4.com-
