[linux-audio-announce] FlacPak - Free lossless instrument compression

by Josh Green

In the past few weeks I've been working on defining a new standard called FlacPak for compressing MIDI instrument patch files. This format uses FLAC (Free Lossless Audio Codec) and zlib to compress audio and binary data respectively. By using FLAC for audio and exploiting other characteristics of instrument files (stereo samples, differing bit widths, etc) much better compression can be achieved then if just using a binary compressor. Currently SoundFont, Downloadable Sounds (DLS) and GigaSampler files are supported. Adding support for a particular instrument format means creating a specific file handler for that format. The decoder on the other hand is generic and sees the resulting file as interleaved binary and audio data. This means other instrument formats can be added in a backwards compatible manner. This also means that FlacPak isn't limited to just instrument patch formats, pretty much any binary/audio combined data format might benefit from FlacPak (provided the audio is mono/stereo 8/16/24 bit). The current reference FlacPak implementation is part of the libInstPatch library that is in active development. A CVS tarball of libInstPatch was made to help in getting feedback from users on the current design of FlacPak so that the format can be finalized. To read more about FlacPak: http://swami.sourceforge.net/flacpak.php To get right to the download (libinstpatch-cvs_20031201.tar.bz2): http://sourceforge.net/project/showfiles.php?group_id=47510 I welcome any feedback on this format and the results obtained. The Swami development list can be found here: http://sourceforge.net/mail/?group_id=47510 I still haven't tested it a whole lot so don't trust your data with it yet. There is also a lot more tuning that can be done to get the compression higher :) Cheers. Josh Green

[linux-audio-announce] ANN: RTMix 0.75 released

by Ivica Bukvic

Greetings! It's my pleasure to announce immediate availability of RTMix version 0.75. RTMix is an interactive multimedia art performance, composition, and coaching interface capable of triggering various DSP applications and/or processes concurrently, as well as offering a tight coordination between computer(s) and live performers. It can also trigger real-time events utilizing MIDI and OSC protocols, and can be in theory networked from a single client with up to 1000 other RTMix clients (personally neither have I had the opportunity to try this and besides the network latency would probably get the best of it anyways). For more info on what it is, what it does, and how it does it, please see the online docs: http://meowing.ccm.uc.edu/~ico/RTMix-doc/ Changelog: *Minor bug fixes in scripting language. *Ability to connect directly to /dev/sequencer (needs to be tested -- any help in bug reporting is greatly appreciated!). This should theoretically enable users to have theoretically infinite number of MIDI devices hooked up to RTMix (using ALSA's aconnect). *UI improvements (mostly "eye-candy"). *New LED icons for improved visibility. *Improved functionality of the Console. *Full documentation included in the distribution (just in case someone missed this one from before :-). *New application icons (16x16 to 192x192). *Smaller tarball. *This is the last version before the milestone 0.8 release with that will sport a completely revamped UI and many new features. RTMix has so far been featured at ICMC 2002 conference (Sweden), SEAMUS 2003 conference (US), in the "Organised Sound" magazine (December 2002), and has been used in several of my works whose recordings are available on my website. If you happened to use RTMix in your work, I would love to hear in what ways you got to utilize its features, as well as how can I make the application better. Thanks! The tarball is available for immediate download from: http://meowing.ccm.uc.edu/~ico/rtmix-latest.tar.gz (4.07MB) For more info, please visit my website and/or the online documentation (provided above). Best wishes, Ivica Ico Bukvic, composer & multimedia sculptor http://meowing.ccm.uc.edu/~ico

[linux-audio-announce] ecasound 2.3.1 released

by Kai Vehmanen

1. A short summary of changes Ecasound's emacs mode, ecasound.el, has been updated to version 0.8.3. Due to severe bugs found in the native Python ECI implementation, the C implementation has been again set as the default. Minor interoperability problems with older JACK releases and Ecasound have been fixed. A bug that caused builds against an external libreadline to fail, has been fixed. Also recording problems with the WinTv 401Dbx and other bt878-based devices have been fixed. This release is compatible with the upcoming alsa-lib-1.0 releases. --- 2. What is Ecasound? Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. Ecasound supports a wide range of audio inputs, outputs and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console mode user-interface is included in the package. Ecasound is licensed under the GPL. The Ecasound Control Interface (ECI) is licensed under the LGPL. --- 3. Changes since last release Full list of changes is available at <http://www.wakkanet.fi/~kaiv/ecasound/history.html>. --- 4. Interface and configuration file changes None. --- 5.

[linux-audio-announce] Ann. Vstserver V0.2.8 and Ladspavst V0.1.5

by Kjetil Svalastog Matheussen

These updates makes it possible to use windows vst plugins in linux applications getting very descent realtime performance. I have successfully ran vst plugins in ardour with 2.66 ms latency. Sources: http://www.notam02.no/arkiv/src/ Linux Vst Compatibility Page http://80.61.20.184/vst/ Tutorial: http://www.djcj.org/LAU/quicktoots/toots/vst-plugins/ Mandrake binaries: (not the latest versions (yet)) http://rpm.nyvalls.se/sound9.1.html Vstserver 0.2.7 -> 0.2.8: ------------------------- -Added SCHED_FIFO priority and locking all mem (mlockall) to the processing thread. Can be used without being root by for example using the givertcap program by Tommi Ilmonen http://www.tml.hut.fi/~tilmonen/givertcap/ To turn off realtime priority, start the vstserver with either the "-NRT" or "--nonrealtime" flag. vst ladspa plugin v0.1.5 - stable ---------------------------------- -Fixed the worst nonrealtimeness for the default mode. When using realtime priority on the vstserver, it should not be necesarry to set LADSPAVST_RT to "1". --

[linux-audio-announce] JACK-0.90.0 Released

by Taybin Rutkin

********JACK 0.90.0******** JACK is a low-latency audio server, written primarily for the GNU/Linux operating system. It can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves. Its clients can run in their own processes (ie. as normal applications), or can they can run within the JACK server (ie. as a "plugin"). JACK is different from other audio server efforts in that it has been designed from the ground up to be suitable for professional audio work. This means that it focuses on two key areas: synchronous execution of all clients, and low latency operation. Source packages for Jack 0.90.0 are available http://sourceforge.net/projects/jackit/ . ********Major Changes******** Buffers can resize during operation. This can be triggered by the user or by the function jack_set_buffer_size(). See the documentation for details. It is new code and still needs a shakedown. It can be enabled with './configure --enable-resize'. If not compiled in, jack_set_buffer_size() returns ENOSYS. Applications should be prepared for it though. Major rewrite of the thread model. This won't affect users. Thanks to the rewrite, jack now has a "freewheeling" mode for faster than realtime operation. It decouples the engine from the soundcard. The alsa driver has 3 new options. --i, --inchannels sets the number of channels to open for input. --o, --outchannels sets the number of channels to open for output. -S, --shorts changes the order of in which the sampleformats are tried. The driver will try to use 16bit samples first and only tries 32bit if this fails. Useful if you digitaloutput card supports 32bit samples but your interface doesn't. ********Minor Changes******** Greatly increased support for other architectures. --version also prints out the temporary directory. Example clients expanded to be more helpful. Many bug fixes. Updated and improved documentation. Portaudio driver works on linux. jack_connect() returns EEXIST if a connection is already made. Addition of jack_get_current_transport_frame (). hw:0 is the default ALSA device instead of "default". Jack's build system has better optimization. --silent option for halting jackd's output. Removal of --tmpdir and --asio options. Will compile with alsa-lib-1.0.0pre1 (the latest). ********Other******** Jack now has a mantis bugtracker at http://jackit.sf.net/mantis/ . Please use that for bug reports. James has written a tutorial for jack programmers available at http://dis-dot-dat.net/jacktuts/starting/index.html . ********Deprecated******** These are deprecated structures and functions that have been deprecated. They will likely be removed in a future release. The jack_transport_info_t struct has been deprecated. Please use jack_position_t instead. jack_engine_takeover_timebase() has been deprecated. Please use jack_set_timebase_callback() instead. jack_set_server_dir() has been deprecated. jack_get_transport_info() has been deprecated. Please use jack_transport_query() instead. jack_set_transport_info() has been deprecated. Instead, define a JackTimebaseCallback.
