[linux-audio-announce] New Linux Audio Column in Linux Journal

by Joern Nettingsmeier

hello linux audio enthusiasts! reading lwn.net this morning i found that the linux journal has a new linux audio column in their online edition, written by dave phillips. the current issue is at http://www.linuxjournal.com//article.php?sid=7283 . the content of this first issue will not be news to you, since it's basically a plug for the world's finest linux audio mailing lists, which you already seem to know about :) still, it's an interesting read, and it has had an effect already: about 30 new subscriptions (in addition to the usual continous growth) since wednesday... (see http://www.linuxdj.com/audio/lad/subscribe.php3 .) to all new readers: welcome aboard! best, jörn -- To someone whose only tool is a hammer, each problem looks like a nail. - Edsger W. Dijkstra, EWD838 Jörn Nettingsmeier Kurfürstenstr 49, 45138 Essen, Germany http://spunk.dnsalias.org (my server) http://www.linuxaudiodev.org (Linux Audio Developers)

[linux-audio-announce] Ecasound 2.3.2 released

by Kai Vehmanen

1. A short summary of changes Support has been added for libsndfile. This allows to access a number of new audio file formats such as W64, PVF and VOC files. Integration with libaudiofile and MikMod has also been improved. Bugs in the native Python ECI implementation have been fixed. Rubyecasound, a Ruby ECI implementation, has been added to the package. A serious memory-leak in list handling functions of the C ECI implementation was fixed. This bugfix also affects C++, Perl and PHP ECI implementations. Compiling Ecamegapedal works again as the header files missing from the previous 2.3.1 release are now again included in the dist-package. Many minor bugs have been fixed. --- 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 * Rubyecasound, a Ruby ECI implementation, has been added to the package. Developer documentation can be found at <http://eca.cx/eci>. Rubyecasound was developed by Jan Weil. * Some files were missing from the previous 2.3.1 release dist-package. This caused the "make check" test procedure to fail, and also prevented from compiling Ecamegapedal against 2.3.1. In 2.3.2 the missing files are once again included in the dist-package. * Libsndfile support has been added to Ecasound (development item 'edi-33'). Support for libaudiofile has also been improved in this release. The user can now compile in support for both libraries at the same time. It is possible to use command-line options to select which library to use for a given file. Similar improvements have been made to the MikMod support. See the ecasound(1) man page for more details. * Some bugs in libsamplerate integration have been fixed. Upgrading to libsamplerate version 0.0.15 or newer is recommended. This release contains a few important fixes that affect Ecasound. A few examples of resampling with Ecasound have been added to the docs: <http://www.wakkanet.fi/~kaiv/ecasound/Documentation/examples.html>. * A severe memory-leak bug was found and fixed in the C ECI implementation. This bug affects applications that heavily use EIAM commands that return lists of strings. The C ECI is used by C++, Perl, PHP and Python ECI implementations. * Bugs in the native Python ECI implementation have been fixed. The C-based Python ECI implementation is still selected as the default, but you can override this with the '--enable-pyecasound=python' option to configure. Note, 'native' here means that ECI API is implemented without linking to any Ecasound libraries. Instead the ECI implementation forks 'ecasound' binary on the background and communicates with it using pipes. This allows for clear decoupling between ECI apps and specific Ecasound version. More information about ECI can be found at <http://www.eca.cx/eci>. 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] 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
