[linux-audio-dev] "LADSPA 2" name

by Steve Harris

Several people have suggested that LADSPA is not a great name for what we are calling LADSPA 2. Reasons for this include: The L, it's not really linux specific, and though /we/ know that its the L of LAD, its not obvious to people outside. The S, it ain't really going to be simple. For someone like me, who is neck deep in triples on a daily basis, 2.0 seems like the paragon of simplicity, but I can imagine 2.9 being quite a beast. LADSPA, (pron. ladspuh?) is a bit of a mouthful, and not exactly catchy. 2.0, it's not going to be obvious to all users that 2.0 and 1.0 are binary incompatible. I'm not sure everyone thinks in major and minor revisions. So, with some trepidation I suggest that we think about naming, with the proviso that if we haven't reached consensus by May 10th we default to LADSPA 2.0, and live with the pain. ---- My suggestion is that we ressurect the XAP name (http://www.google.com/search?q=lad+xap) It stood for Xap Audio Plugin IIRC. Pros: it's short*, relatively unused** and pronouncable*** Cons: xap.{com,org,net} will have gone long ago (too short), theres a small ammount of baggage. - Steve * I've typed LADSPA_ a lot ** There is a home automaption protocol, called xAP that takes plugin modules. Though I think we started using the name around the same time, they seem like nice people and we should OK it with them. *** "zap"@en-gb

Slackware 10.2 doesn't come with sigc++. You will have to get the source, compile and install it before attempting to compile anything that uses it, such as cheesetracker. It's not hard though - sigc++ compiles and installs cleanly under Slackware 10.2 (for me at least) using the normal ./configure make make install process. Regards jonathan

(looking at http://xap-plugins.org/artwork.html). And it's not too VST -alike, as XAP doesn't share a single letter with VST. > Cons: xap.{com,org,net} will have gone long ago (too short), theres a > small ammount of baggage. I think we would select a short name anyway. Most of them are gone already, so we have the same problem whichever [a-z][a-z][a-z] we select :) Sampo

[linux-audio-dev] Todays "LADSPA2" update

by Steve Harris

I've written a first cut at an ontology/schema for the plugin RDF: http://plugin.org.uk/ladspa2/ladspa-2.ttl The term schema is a bit misleading, as it doesn't really enforce anything, it really just gives you some hints about what to write. The bulk of it is english text to explain the meaning of the bits that are no longer in the .h I tried to write it as clearly as possible, but the machine readable parts might still be a bit cryptic and there could be errors. Shout if there's any bits that don't make sense. - Steve

[linux-audio-dev] LAC 2006 Live Streams

by Joern Nettingsmeier

hi *! the linux audio conference 2006, which takes place at the zkm in karlsruhe/germany from april 27 to april 30, will be streamed live for your convenience, inspiration and enjoyment. all presentations (which are listed on http://lac.zkm.de/2006/program.shtml) are covered as ogg vorbis audio streams in two bitrates (one for modem users and one for slightly-more-broadband users) and ogg theora/vorbis a/v streams (for broadband users only). to watch and/or listen, you can use a recent version of mplayer, vlc or curl | theora123, if you prefer. the stream urls are listed at http://lac.zkm.de/2006/streaming.shtml. we will start test streams tomorrow by 12:00 utc+2. as always, there will be chat channels to go with the streams, where you can report problems, discuss the presentations and also ask questions which will be relayed to the live audience by the local chat operators here at zkm. these channels are #lac2006 for general issues and chitchat, and #lac2006-track1 and #lac2006-track2 for questions and remarks about the current presentation, all on irc.freenode.net. you will be able to download the presentation slides in advance to read along as you listen and watch. the quality of the video streams will not be sufficient to read the projections, but you should easily be able to make out which slide is currently up. on behalf of eric rzewnicki (who did most of the streaming work this year) and the rest of the lac organizational team i wish you lots of fun with the streams. kudos again to the icecast team, especially to karl heyes, all the folks at xiph.org who brought us all those great free multimedia codecs, and the crew here at zkm for their great support and cooperation! best, jörn

[linux-audio-dev] [ANN] Simple Sysexxer 0.1

by Christoph Eckert

Hi all, as it is LAC time, it's also release time :) . Simple Sysexxer is a GUI sysex tool comparable to Sysexxer, but it's based on Qt4 (no KDE dependency) and ALSA only (no OSS dependency). Theoretically it should also build and run on Mac OS X, but I didn't try it yet. Feedback and bugreports are always welcome. Information and source code: http://www.christeck.de Best regards ce

[linux-audio-dev] all-purpose xplatform audio decoding library?

by Leonard "paniq" Ritter

maybe someone here can help? <paniq> i need a decoder library that works on win32/linux, can decode wav/ogg/mp3, can seek with sample precision and supports rendering of userdefined frame sizes <larsl> I'd say libsndfile, but it doesn't do MP3. <paniq> which isnt that bad tho. i hate mp3. <larsl> http://www.mega-nerd.com/libsndfile/ <paniq> no ogg support <paniq> only support for wav files <paniq> i'm not fond of adding separate libs with different apis to access different audio codecs -- -- leonard "paniq" ritter -- http://www.mjoo.org -- http://www.paniq.org
