But the latest version only compiles with a quite old version of wine, not the newest. So if you compile the vstserver while having the older … [View More]

[linux-audio-dev] Creamware's Scope Fusion Platform on Linux/OSX

by Jan Weil

I was browsing the comments to this (Linux Audio) article[0] on OSnews.com when I found this link[1] to a Creamware Scope forum[2]. It states that Creamware's Scope Fusion Platform[3] is about to be ported to Linux and OSX. This is a community effort led by Frank Hund of Creamware and Willie Sippel (which is a funny name BTW) and they are looking for skilled developers. The posting is from March 19th.

[linux-audio-dev] LADSPA 2.0 notes

by Steve Harris

These are just my thoughts and some notes about "LADSPA 2.0", the mail I sent yesterday was the notes I made in the meeting that everyone agreed to, so I didn't want to add my personal thoughts. Mentally prefix everything below with "I think...". I wasn't particuarly happy with the tone of the meeting report, it was a bit authoritarian for my tastes, but the LADSPA 1.x discussions weren't really going anywhere, and we had Paul and Stefan at the conference, Richard had made his feelings clear … [View More]and we had a reaonable represenation from the various user/developer groups, so Paul declared us quorate ;) The .h file will contain a structure much like the 1.x one, but it will only have: * an identifier of some kind (like label/uid, maybe with stronger semantics) * a port count * a list of ports (float *'s and types, eg input control port etc.) The other stuff (names, hints, defaults etc.) will be sotred in an external metadata file. The float *'s obviously have to be in the struct as thier a point of reference, and the port types allow a host that just has the .so file to be compliant, even if it cant do anything intellignet, or present a UI. There will be a provided library for handling the metadata format. The format of the metadata is up for discussion, Ideally it should be something that is easy to parse so people dont have to use the ladspa-sepcific library if they dont want to. The library API will be very thick, eg get_defaults(plugin) returning an array of default values - that kind of thing - hiding the details of the metadata format. The reason for this supprising decision (well, I was supprised) was that everyone agreed that the current mecahnism where some details about the plugin are in the struct and some is external is not ideal, and the prevailing opintion is that external metadata is easier to extend without complicating the struct. There are lots of general, technical reasons why external metadata is preferable, but theres not space to go into them here. Several people expressed concens about the way that extending the struct we have now either blocks, or complicates future expansions we might want. The reason that LADSPA 2.0 will have no more features (than 1.1 + what we agreed in the meeting) is to allow it to be defined quickly and easily - if the fetures set is not up for discussion it should be easier to decide. There is the option for 2.1 etc. which can add more features once the dust from 2.0 has settled down. Things like the VST-LADSPA bridge that can generate plugins on the fly will need a mechanism that allows the dynamic plugin to squirt metadata generated dynamically into hte host, through an API. The exact API will depend on the metadata format. - Steve [View Less]

[linux-audio-dev] [ANN] Ecasound 2.3.3 released

by Kai Vehmanen

Hello all, this year's first stable Ecasound release is now out! Most of the final tuning for this release was done last Sunday while watching and listening to the last sessions of 'laconf2'. Many thanks to all the organizers and participants! And special thanks for the excellant net coverage of the event! But now, back to the 2.3.3 release -- here are the details: 1. Summary of changes Bugs in ecasignalview, effect presets, NetECI protocol parser and the C ECI implementation have been … [View More]fixed. Many build system issues, including errors in building against libsndfile-1.0.4 and older, have been resolved. A separate section covering ecasound.el, the ecasound emacs interface, has been added to the Ecasound Control Interface Guide. The Ecasound User's Guide has also been updated. --- 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 * Preset handling fixes: When saving chainsetups containing presets, values of preset parameters were not saved correctly. Also problems with presets containing untitled parameters have been fixed. * New ecasoundrc(5) setting "autodetect" for "default-output" has been added. When selected, libecasound will check for JACK support and whether a JACK server is running, if not found, check for ALSA, then OSS, and finally fallback to using "rtnull". This feature is especially useful to apps such as ecaplay. * Fixes to ecasignalview: Proper cleanup after receiving an interrupt from keyboard (SIGINT/CTRL-C) has been added. Originally tested on FreeBSD, but helps on Linux as well. * Ecasound Interactive Mode (EIAM) updates: Added new command 'map-ladspa-id-list' to allow listing the available plugins by their unique ID numbers. A special case value of '-1' is now understood by 'cs-set-length'. This allows undoing any previously set length value. * Ecasound Control Interface (ECI) updates: Added a section on ecasound.el - the Ecasound emacs interface - to the ECI Guide [1]. Several bugs have been fixed in the ECI C implementation. A serious bug in NetECI protocol parser, that caused parsing long (over 32 chars) commands to fail, has also been fixed. * Documentation updates: The Ecasound User's Guide [2] has been updated. Also, a bug in the groff source for the ecasound(1) man page that prevented man from showing the last five pages of the document, has been fixed. * Build system fixes: Problems in building against libsndfile-1.0.4 and older have been fixed. 'libecasound-config --libs' has been fixed to return the full list of external libraries. Based on recent discussions on linux-audio-dev, minor changes have been made to processing CFLAGS, CXXFLAGS and LDFLAGS. Full list of changes is available at <http://www.wakkanet.fi/~kaiv/ecasound/history.html>. --- 4. Interface and configuration file changes * ecasoundrc(5) - "default-output": new value "autodetect" (default) --- 5. Contributors Patches - Accepted code, documentation and build system changes Michael Ewe (2) -- bugfixes to ecasignalview and ECI C impl Mario Lang (1) -- section on ecasound.el to ECI Guide Eric Rzewnicki (1) -- set of updates to Ecasound User's Guide Kai Vehmanen (n/a) -- various Bug Hunting - Reports that led to bugfixes (items closed) Pierre Lorenzon (1) -- bugs in ecasound's daemon-mode protocol parser Jan Weil (1) -- cs-save dit not save preset parameters Feature suggestions - Ideas that led to new features (items) Jan Weil (2) -- map-ladspa-id-list command, -t:1 option --- 6.

[linux-audio-dev] (web-based) interactive sound art?

by Niklas Werner

Hi .*, I am doing my PhD at the University of Waikato's Music Department, NZ with Ian Whalley. I am going to develop a Web-based interactive sound art system allowing composers/players to incorporate aesthetic approaches from electronic music, net.art, sonic art and soundscapes. I am trying to get away from using MIDI in favour of OSC and direct DSP on the audio (That's why I'm thinking of using SuperCollider). I will direct much attention to the musical quality of the system's output, … [View More]
