http://www.ecs.soton.ac.uk/~njl98r/code/ladspa/njl-plugins/njl-plugins-0.2.… An implementation of the continuous Risset scale gives me the confidence to announce this suite of LADSPA plugins. Thanks to Steve Harris for his invaluable contributions to the design and implementation. Also, if any XMMS LADSPA users lurk on this list, a bugfixed version is now available from my home page along with all my Linux audio software. http://www.ecs.soton.ac.uk/~njl98r/code/ladspa/ Nick.

[linux-audio-announce] [ANN] Ecasound 2.4.0 released

by Kai Vehmanen

1. Summary of changes An annoying bug with handling filenames with whitespace has been fixed. Integration with libsamplerate and other resamplers has received a lot of attention and many bugs have been fixed. Error reporting has been improved when loading invalid chainsetups. A new sum-mixdown mode has been added to the engine. Some minor cosmetic changes have been made to the output produced by the console ecasound interface. A log message history mechanism has been added to the engine to help ECI app and script development. --- 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. Primary platform for running Ecasound is GNU/Linux. Ecasound can also be run on many UNIX-derived systems such as FreeBSD, Mac OS X and Solaris. Limited support for Windows is available through Cygwin. Ecasound is licensed under the GPL. The Ecasound Control Interface (ECI) is licensed under the LGPL. --- 3. Changes since last release * Fixed a bug present in 2.3.3 and 2.3.4 releases which broke handling spaces in filenames. This affected all file formats handled via external tools (ogg/mp3/flac/m4a/...). * Improved support for handling commas in parameters such as filenames given to ECI commands and to the console ecasound interface. A section on "Filenames with commas not handled correctly" was added to the Ecasound User's Guide that provides more information about how commas and other special characters are handled by ecasound. * Log message history added. The EIAM command 'int-log-history' shows you the recent log messages printed via Ecasound subsystem, and 'int-set-log-history-length' sets the history buffer size. This should be a very useful tool for debugging ECI scripts and apps (insert int-log-history at suitable places in your code to get a detailed log of what happened in the engine). * Cosmetic changes to ecasound output. In the interactive mode (does not affect wellformed output or -D), ecasound now wraps all lines so that they fit into 74 columns. I've copied the "... " prefix style from the python interpreter to print messages that do not fit on one line. * Code added to analyze problems with chainsetups. If you now make common errors like: ecasound -i foo.wav -i foo.bar -o rtnull or ecasound -a:1 -i foo.wav -a:2 -i bar.wav -o rtnull ... ecasound will try to explain what is wrong with the configuration. This is related to edi-40, "Update to error and warning reporting mechanisms", development item. * Integration with libsamplerate and other resamplers has received a lot of attention and many bugs have been fixed. Special thanks to Aaron Heller, Kamil Wencel and Julien Claassen for the extensive testing! * Fixed segfaults related to buffersize and samplerate change events from JACK. Ecasound now gracefully shuts down if one of these events is received. Note that Ecasound is still not able to adapt to a new buffersize or samplerate on the fly. * A new 'sum' mixing mode has been introduced. Traditionally Ecasound has used the averaging method of mixing multiple input channels into one output channel. This avoids the risk of clipping, but can lead to suprising results in certain use-cases. The 'sum' method is closer to the way an analog mixer works. To retain backwards compability, the 'avg' mixing mode is still used as the default. Full list of changes is available at: - http://www.eca.cx/ecasound/history.php --- 4. Interface and configuration file changes * In string lists returned by ECI commands, all commas are now escaped with backslashes. This change was needed to make unambiguous parsing of the return values possible. * Ecasound console output is pretty-printed to fit 74 columns. This does not affect output in well-formed (-d:256) and plain-text (-D) modes. --- 5. Contributors to this release Patches - Accepted code, documentation and build system changes * Vitaly Belostotsky and Junichi Uekawa (1): Bugs in compressor presets defined in effect_presets * Steve Harris and Tim Blechmann (1): Float anti-denormal routines from swh-plugins * Eric Dantan Rzewnicki (1): Manpage fixes Bug Hunting - Reports that led to bugfixes (items closed) * Jan Weil (3): Comma-escaping problems with EIAM return values * Aaron Heller, Kamil Wencel and Julien Claassen (1): Bugs in resampling with libsamplerate. * Didier Bellamy (1): Bug in aac/m4a encoding * Erik de Castro Lopo (1): Bug in resampling with libsamplerate * Jesse Chappell (1): Bug in resampling with libsamplerate * Frederik Eaton (1): Whitespace handling bugs ogg/mp3/ext support * Mario Lang (1): Regex metachars in LADSPA plugin description fields were not properly escaped * Philippe Schelté aka Dubphil (1): Denormal problems in Ecasound filters. * Junichi Uekawa (1): Whitespace handling bugs ogg/mp3/ext support. --- 6.

[linux-audio-announce] AMD to sponsor linuxaudio.org stand at Sounds Expo

by Daniel James

Hello all, AMD has offered significant sponsorship which will allow linuxaudio.org to have a stand at the Sounds Expo music technology trade show in London, 14-16 April 2005. This will be our second exhibit at Sounds Expo, following generous sponsorship from the AGNULA project last year. As you may know, AMD has worked closely with the Linux development community to ensure that Linux can run natively on its 64-bit x86 processors. There is also at least one shipping Linux-based pro audio product on the market with an AMD processor inside. I will be at Sounds Expo in person, but other people who can help on the stand are also needed, mostly to answer questions about Linux and libre software from musicians, sound engineers and hardware manufacturers. It need not be for all three days - if you can help out on just one day, that would be great. This is a great opportunity to once again put libre audio software directly in front of the target users, so please help if you can. Cheers! Daniel James Director http://linuxaudio.org

[linux-audio-announce] GOTO10 Pure Data Workshop in the Netherlands Media Art Institute

by goto10

sorry for X and Y _pd.workshop 4+1 days 23-3-2005 until 27-3-2005 Netherlands Media Art Institute, Amsterdam in collaboration with goto10.org Guests Tom Schouten (Author of PDP, video processing within PD, Belgium) and Aymeric Mansoux (Artist, France) Fee 150,- Euros Admission Due to the limited capacity, applicants will be selected according to relevant experience and motivation. Please note all materials should be written in English. Applicants can send a mail stating name, adress, telephonenumber, and a short overview of your skills and motivation to : carlijn at montevideo.nl BEFORE MARCH 11th _Pure Data Pure-Data is a "real-time" graphical programming environment for audio and graphical processing. It was planned as a free, better and more stable Max/fts, which has also been developed by Miller Smith Puckette at IRCAM. It is used as a rapid prototype-software for DSP-algorithms, and also as a music instrument and universal multimedia-software. Being a mature project now, Pure-Data is getting more and more popular in the academic field for teaching and exploring computer music and new media art. It's hard to describe the possibilities of such an environment as its field of creation is almost infinite. From audio processing, to video, 2D/3D, interactivity, on-line experimentation, streaming and sensors, Pure-Data can handle all of these and provide a rock stable system which is perfect for performances and installations of any kind. _PDP PDP is a set of external objects to PD developed by Tom Schouten. They are based on the idea of processing data in packets. While it is primarily used for video, the basic structure of PDP allows any kind of data to be processed into any other kind of data. Images can be converted to textures, that can be changed into sound, re-rendered again as image, and so on. The possibilities are endless. _Presentation Sunday March 27th (from 15:00 until 17:00) a presentation of the workshop will take place. This presentation will be open to an audience invited by the participants. A short overview of the workshop will be given and the participants can share the creations they have made with each other and with the audience. Tom Schouten (BE) Artist and author of PDP.

For OSX there is minimal support. The last year PDP has undergone a major restructuring which mainly aims at a wider platform support and 2D/3D drawing primitives (aka 3DP). For the OSX users out there: keep an eye on it! We plan to add Altivec, Quicktime and OpenGL support to use them macs for what they're worth. goto10.

[linux-audio-announce] KMidiTracker 0.5.10

by David Moreno Montero

Hi, I'm pleased to announce KMidiTracker 0.5.10, the new revision of my KDE Midi Tracker, or Step Sequencer, as you wish to call it. New features include SysEx capture of messages, columns are muteable, and finally MIDI clock messages are undestood (as master and slave), so it can finally interact with other sequencers as Rosegarden4. You can get it from http://www.monasteriomono.org/programs/kmiditracker/ Small introducion to KMidiTracker (from the website). ------- Introduction KMidiTracker is a MIDI Step Sequencer. A Step Sequencer is a sequencer in witch the MIDI notes are delivered at regular time intervals, usually a 1/4th of a quarter note. As such it is not as versatile as a regular sequencer as [Rosegarden], but allows very easy creation of loops and sequences. The use of the [MIDI Clock] allows several sequencers communicate clock events, so it is possible to join several sequencers, with diverse focus, to make one single synchronized composition. KMidiTracker is similar to trackers like [FastTracker], [ScreamTracker] or [Buzz], but only the Tracker; no actual sound is emmited. Only MIDI signals. The Tracker divides songs in tracks, each one have several patterns that are arranged as sequences. Time advance in steps that depend on tempo, and in each time step a new MIDI note may sound, or a controller event may be sent. You can have several columns of notes and/or controllers for each pattern, and pattern length is configurable. KMidiTracker Features * MIDI oriented Step Sequencer * ALSA MIDI input/output * Keyboard input * Graphical Controller edition * Controllers include MIDI Controllers, SysEx Controllers and PitchBend * MIDI Master Clock (master and slave) * Linux RTC timer or MMC if avaliable for perfect timing * Tracks and columns in patterns muteable * SysEx parameters. Can be loaded from binary file, manually inserted in hex, or captured from midi input. * Variable Time Signature * Load/Save * KDE application: easy menu, toolbar and shortcuts changes * Everything can be changed in realtime: notes, arrangement, loops, controllers, load/save, new tracks or patterns, delete tracks or patterns... * GPL license -------- Thank you! --- http://www.monasteriomono.org david(a)monasteriomono.org

[linux-audio-announce] LAC 2005: Conference programme online, register now!

by Frank Neumann

Hi all, the conference programme of the International Linux Audio Conference 2005 (LAC2005) in Karlsruhe, Germany, on April 21st-24th, 2005, is now online at http://lac.zkm.de. Small changes are still possible, though. Also, registration (free) for the conference is now possible, too, at http://lac.zkm.de/registration.shtml Quote from that page: "Admission to this year's conference requires a registration. This helps us to estimate how many visitors we may expect, what individuals the audience is made of, and allows to produce name tags for all attendees so that it becomes easier to identify each other. The registration is free - and so is the conference (except for the concerts). The data you enter here is purely for our own informational purposes, and will never be given away or sold to anyone. If you register, no confirmation of any kind will be sent to you. You can even completely omit the E-Mail address, but providing it makes it easier for us to tell if there's a real human behind a registered identity or rather a robot/spambot." So, there you have it. Go ahead, read, register and come :-) Thanks for reading, The LAC05 organization team: Götz Dipper (ZKM) Frank Neumann
