[linux-audio-announce] Sweep 0.5.4 -- !ybburcS olleH

by Conrad Parker

Sweep 0.5.4 Development Release ------------------------------- Sweep is a sound wave editor, and it is now also generally useful as a flexible recording and playback tool. Inside lives a pesky little virtual stylus called Scrubby who enjoys mixing around in your files. This development release is available as a source tarball at: http://prdownloads.sourceforge.net/sweep/sweep-0.5.4.tar.gz?download Changes since version 0.5.3 (September 5 2002) include bug fixes for playback during destructive operations and for edits of tiny regions, and improvements in configuration checks for libsndfile-1.0.0. Additionally, scrubbing is now working for reverse playback, and has been tuned for responsiveness independent of sample rate. There is now a web page introducing Scrubby and outlining a few simple editing and live performance techniques: http://www.metadecks.org/software/sweep/scrub.html Summary of library dependencies: * GTK+ 1.2 (standard in most distributions) * libsndfile-1.0.0, available at: http://www.zip.com.au/~erikd/libsndfile/libsndfile-1.0.0.tar.gz * libtdb, available in many distributions or at: http://www.sourceforge.net/projects/tdb Screenshot: http://www.metadecks.org/software/sweep/images/screenshots/sweep_20020813.p… Sweep is designed to be intuitive and to give you full control. It includes almost everything you would expect in a sound editor, and then some: * precise, vinyl like scrubbing * looped, reverse, and pitch-controlled playback * playback mixing of unlimited independent tracks * looped and reverse recording * internationalisation * multichannel and 32 bit floating point file support * LADSPA 1.1 effects support * multiple views, discontinuous selections * easy keybindings, mouse wheel zooming * unlimited undo/redo with fully revertible edit history * multithreaded background processing * shaded peak/mean waveform rendering, multiple colour schemes Help wanted! Sweep needs testing; please report any problems encountered! Urgent development is required in the following areas: ALSA and Jack support, updating of translations and user documentation. (NB. Sweep works fine with ALSA under OSS emulation -- the native ALSA support needs some fixing). Sweep is Free Software, available under the GNU General Public License. More information is available at: http://www.metadecks.org/software/sweep/ Thanks to Pixar Animation Studios and CSIRO Australia for supporting the development of this project. enjoy :) Conrad.

[linux-audio-announce] GStreamer 0.6.0 released

by Christian Fredrik Kalager Schaller

GStreamer "Hottest Pick" 0.6.0 released[*] The GStreamer team is happy to announce our first ABI stable release series. The 0.6.x series of the GStreamer streaming-media framework. At this point in time GStreamer is fully functional for creating audio-based applications, as shown by applications such as gnome-sound-recorder, Rhythmbox and nautilus-media. Video-based applications still have some issues at this point, but we plan on solving those issues during the 0.6.x series in an ABI compatible way. We will also be releasing a development 0.7 release series, in which we will work on such things as the remaining video issues and the interactivity support which is needed for DVD menus and SWF (Flash). This means developers working on apps needing these services can use the 0.7 series for development and then enable 0.6 support as these additions optionally get backported to 0.6 once they are stable and work well. Thread issues and GStreamer Many of GStreamer's features relies heavily on threads. Unfortunately everything is not rosy in the Linux world of threads. If you have a glibc version installed compiled with i686 optimizations (which uses a different codepath than standard i386 glibc), there is a good chance you will experience thread-related crashes in gstreamer-based applications. There are a few workarounds to this available. * You can use an i386 glibc package instead. (Since this is the only one shipping with Debian, debian users do not experience this issue.) * You can also try running the gstreamer-based applications using the command-line option --gst-scheduler=opt, which invokes a newly created scheduler that does not use threads. This scheduler is very new however so you might encounter other issues when using it. Please report issues to our bugzilla. The GStreamer applications we ship all check for both gstreamer-0.6, gstreamer-libs-0.6 and gstreamer-play-0.6; if those aren't found the 0.7 version of those files are checked for. We suggest anyone making GStreamer-based apps do the same. We are starting to have a really nice collection of applications under development using GStreamer. If you are looking for something specific check out our applications status page: http://www.gstreamer.net/status/?category=2 Features * Pipeline based media architecture * Over 130 plugins * All parts interchangeable * Few dependencies, only glib, popt and libxml for core (libxml optional) * Python Language bindings * Good documentation * Will be widely deployed through bundling with GNOME 2.2 * Design catering also for applications needing low-latency * Highly portable, already running on most mainstream CPU's * Modular design and use of 3rd party best of breed libraries means no bloat * LGPL licensing lays no restrictions on application developers licensing. * Easy for applications to ship their own plugins to the core as needed * Compiles with both GCC and Forte compilers * Tested to run on Linux, FreeBSD and Solaris GStreamer Homepage More details on these features can be found on the project's website, http://gstreamer.net/. Download and build instructions: http://www.gstreamer.net/releases/0.6.0/ Support and Bugs We use Gnome's Bugzilla (http://bugzilla.gnome.org) for bug reports and feature requests. The "product name" is GStreamer (capital G). Please do the following before writing a bug report : gst-feedback &> feedback 2>&1 and attach the file "feedback" to your bug report, so that we have some information useful in the debugging process. Developers GStreamer is hosted on SourceForge. All code is in CVS and can be checked out from there. Interested developers of the core library, plug-ins, and applications should subscribe to the gstreamer-devel list. If there is sufficient interest we will create more lists as necessary. We are still looking for people with access to FreeBSD, Solaris, HP-UX, Irix and True64 that would be willing to try building and testing GStreamer. Patches fixing such problems are also more than welcome. Contributors to this release Patches to the core of Gstreamer * Wim Taymans <wim.taymans(AT)chello.be> * Erik Walthinsen <omega(AT)temple-baptist.com> * Thomas Vander Stichele <thomas(AT)apestaart.org> * David I.

by Ivica Bukvic

Hi all, Just to share the good news that Linux got some exposure in the latest edition of the Organised Sound journal (pub. by UK's Cambridge Journals). Stuff covered is RTMix, as well as JACK/Linux audio. Big thanks go to Paul Davis for the help with the benchmark info, as well as everyone else in the Linux community who have made Linux a formidable multimedia platform. For more info on the journal see (it's just an abstract page about the actual journal -- I am still trying to find out how to locate the darn article online :-) http://titles.cambridge.org/journals/journal_catalogue.asp?mnemonic=oso Cheers!

[linux-audio-announce] ecamegapedal 0.4.0 released

by Kai Vehmanen

1. A short summary of changes Sliders for parameter control and text inputs for lower and upper bounds have been added as well as support for LADSPA-1.1 and ecasound effect parameter hints. There has been some user interface improvements and a native JACK support has been added. Updated to use the new ecasound-2.2 libraries. --- 2. What is ecamegapedal? Ecamegapedal is a real-time effect processor software with a graphical user interface for controlling the effect parameters. It is meant to be used as a virtual guitar-fx or studio effect box. In addition to real-time operation, ecamegapedal also supports reading from and writing to audio files. All audio object and effect plugin types provided by the ecasound libraries are supported. This includes ALSA, JACK, OSS, aRts, over 20 file formats, over 30 effect types, LADSPA plugins and multi-operator effect presets. Ecamegapedal's implementation is based on ecasound and Qt libraries. Ecamegapedal is licensed under the GPL. --- 3. Changes since the last stable release * Added native JACK support. If compiled with JACK support enabled, ecamegapedal will upon startup fetch the current engine parameters from the JACK server, and initialize the ecamegapedal configuration to work with JACK. In practice this means that you don't have to manually set the buffersize and sample rate parameters to use ecamegapedal with JACK. * Support for LADSPA-1.1 and ecasound effect parameter hints. * Text inputs for overriding default upper and lower bounds for parameter values. * Sliders for controlling parameter values. * Pixmaps for transport control buttons. * Takes advantage of the newly released ecasound 2.2.0 libraries (does not work with older ecasound releases). * Should work with all released Qt2 and Qt3 versions. Tested with qt-2.3.2, qt-3.0.5 and qt-3.1.1. --- 4. Contributors Patches Kai Vehmanen Arto Hamara Bug Hunting Jaakko Prattala Justin Rosander Junichi Uekawa Feature proposals Dan Lyons --- 5.

[linux-audio-announce] ANN: k_jack v0.0.0.5 and Mammut v0.15

by Kjetil S. Matheussen

k_jack is a jack reimplementation, and mammut is a very special sound transformating sound editor. Download from http://www.notam02.no/arkiv/src/ New in mammut v0.14->v0.15: --------------------------- -Removed the synth transform. It was not supposed to be there and had no function. -Fixed the wobble transform. Segfaulted with mono-files. (Bug found by Dave Phillips) k_jack V0.0.0.5 ALPHA - EXPERIMENTAL ------------------------------------- ABOUT k_jack currently consists of k_jackd~, libk_jack and libaipc. k_jackd~ is a jack server external for pure-data. libk_jack is (supposed to be) a (somewhat) libjack compatible library. Jack applications that want to contact k_jackd~ instead of jackd must (somehow) be linked with libk_jack and libaipc instead of libjack. k_jackd~ does not speak with libjack, and jackd does not speak with libk_jack. libaipc is a library for audio interprocess communication, based on code from the vstserver. A preview version is included with this version of k_jack. (API is not settled.) By using libaipc for interprocess communication, and letting PD take care of various low/mid/high-level audio-stuff, only a few hundred lines of code is currently used for this implementation of a simple jack system. k_jackd~ and libk_jack are not based on the jack sourcecode found at jackit.sf.net, except for protos in the header files. COMPILE 1. Go into the aipc/src folder and write make to compile up libaipc.a 2. Go into the library folder and write make to compile up libk_jack.a 3. Write make to compile up k_jack~.pd_linux. 4. Relink you jack application(s) somehow. USAGE 1. Start pd with the "-lib k_jackd~" option. 2. Start a jack application linked with libk_jack. 3. Make an object in pd called "k_jackd~ <clientname>". Correct number of inlets and outlets will be made automaticly. That should be it. Later, when things get more stable, point 3 can do point 2 automaticly. WHY use k_jackd~ ? 1. Simple. Only the clientname is used, not the portnames. 2. Easy and powerful interface to control the audioflow. 3. Good performance. Shouldn't be necessary to run as root. TESTED CLIENTS simple_client, freqtweak, ceres. BUGS Crashes pretty often. Does not clean up. Huge risk of not freeing shared memory in the current implementation: Client must exit before server, and client must not crash. And server must not crash. CONTACT Send ideas (especially about the k_jackd~ object syntax), comments (especially about the libaipc API), questions, code, food, etc. to k.s.matheussen(a)notam02.no --
