Re: [LAD] Non-daw, non-sequencer (fork?)

But am > incredibly busy at the moment. Danni, That would be cool! I posted this cause it will be a lost for Linux Audio if this dies imho. Btw I think I found one disadvantage in the workflow of non-sequencer. You can choose a scale to work in, but the disadvantage afaik is that you can't choose notes outsides that scale. Maybe I'm wrong, but if I'm right it seems to narrow the possibilities quite a bit. \r

Is there a DSSI version available? Ralf -- Taking a look at the screenshots reminds me to ask something OT: Does anybody know an insiders' tip were to get CME microchips for old faithful analog synth by a fair price?

linux and ambiophonics

by Bearcat M. Sandor

Folks, Is there anyway to set up an ambiophonic (not to be confused with ambiosonic decryption) filtering on a Linux system? I'd prefer 4 channel if possible. I'm aware of brutefir, but i doubt i have the knowledge to set up so complicated a system equation by equation. Are there brutefir scripts out there for it? Anyone know of a ambiophonic ladspa plug in or something? Thanks, Bearcat M Sandor

Audio booth at OpenSourceExpo 2009 in Karlsruhe, Germany?

by Frank Neumann

Hi, [this is mostly addressed to Linux Audio friends from Germany's Southwest] from November 15th-16th, 2009, the German Software&Support Media Group is hosting the "OpenSourceExpo" in Karlsruhe, Germany. I am not exactly sure yet about its target audience, but it appears like a "small brother" of the LinuxTag with a more local attitude. They offer free booth space, tables and wLan access for free software projects, and I was thinking about applying for a booth there to show off some of the current Linux Audio developments there, as we did when LinuxTag was still in Karlsruhe (2002..2005 or so). That would mean setting up the booth with computer, monitor, mixer, speakers, keyboard etc, and preparing some demo material. However, this task would need 1 or 2 more volunteers to man the booth during that time (please note: This is on a Sunday+Monday!). If anyone is interested, please get in contact with me off-list (or even here). Find more information about the OpenSource Expo here: http://www.pro-linux.de/news/2009/14664.html (german) http://it-republik.de/konferenzen/opensourceexpo09/ Thanks for reading, Frank

jens, i assume you meant this to go to the list?

interesting CELT presentation

by Jörn Nettingsmeier

those who are following the development of the xiph CELT low latency codec might find this presentation interesting: http://www.celt-codec.org/presentations/ torben has implemented CELT support in netjack1, and this video helped me a lot in understanding how it actually works.

Fwd: [Flac-dev] (Universal) Ambisonic implementation

by Paul Davis

i thought perhaps that our resident ambisonics gurus/interested parties should take a look at this. --p ---------- Forwarded message ---------- From: e deleflie <edeleflie(a)gmail.com> Date: Thu, Sep 17, 2009 at 8:21 PM Subject: [Flac-dev] (Universal) Ambisonic implementation To: flac-dev(a)xiph.org Hi Flac Developers, My name is Etienne Deleflie, I'm the founder of http://www.ambisonia.com and, more recently, http://soundofspace.com. Myself and the community I serve are looking for a lossless file format that can encapsulate ambisonic encoding. To this end a specification has been drafted, and is nearing stability, that describes practical features designed to get the most out of ambisonics. That spec is accessible here: http://ambisonics.googlegroups.com/web/Universal_Ambisonic_0.96.pdf I'm wondering if the FLAC community might be interested in implementing a lossless implementation of that spec. I know there are some current incompatibilities. I'm also aware that there are certain open source processes involved around implementing new features. I'd be happy to get involved with those processes if someone expressed interest at implementing these features. regards, Etienne _______________________________________________ Flac-dev mailing list Flac-dev(a)xiph.org http://lists.xiph.org/mailman/listinfo/flac-dev

Fwd: Re: LV2 port groups

I was not a member of LAD when the "LV2 port groups" discussion was running in August. (First few lines from messages of Jörn Nettingsmeier and David Robillard, below.) Now I am 'on list' can I jsut check I have answered everyone's queries?
