Hi! Requirements in order of importance, highest first: - not likely to get us into legal trouble - no too obvious negative interpretations/associations ("too obvious" because it's too hard, internationaly, otherwise) - no conflict with established open source projects - easy to search for Pretty much every 3 letter combo is in use by some company or institute. Few are pronounceable. It's similar with 4 letters. Suggestions with few (and not relevant looking) or no Google hits: splugs - stream processing plugins sppib - stream processing plugins in bundles laspib - linux audio ... buspp - bundled stream processing plugins streamins - streaming/stream-processing plugins sprocins - stream processing plugins [Streaming because there are continuous i/o streams of data as far as I understand, while there's no limitation to audio/float anymore. Corect me if I'm wrong.] Cheers, Thorsten Wilms

[linux-audio-dev] This weeks changes to LV2 (née LADSPA2) strawman examples

by Steve Harris

http://plugin.org.uk/ladspa2/ Changed name of the port shortname property to "symbol", which hopefully implies more the right thing. Added Rate before Control and Audio port names to hopefully make thier menaing clearer for people who may not come from a LADSPA background. This is just fiddling really, so I think it's starting to settle down. - Steve

[linux-audio-dev] surround multimedia SW on Linux

by Alfons Adriaensen

I've had this request on a non-Linux list: Can you provide more feedback (about) ... multimedia players capable of decoding Dolby AC3, DTS, DVD-Audio, etc. on a Linux machine? What about software players running on a CAR-PC and surround-capable? I know very little about the whole field of multimedia players for proprietary formats on Linux. Can someone fill in the gaps ? - which apps are available ? - are they open-source ? - what interfaces (ALSA, JACK, OSS, ...) do they have ? - do they require Windoze emulation ? - what is their maintenance state ? - etc. Many thanks, -- FA Follie! Follie! Delirio vano e' questo!

[linux-audio-dev] Edirol UA-101 support?

by Ákos Maróy

Hi, I saw this thread earlier on this list about the Edirol UA-101 external audio interface: http://lalists.stanford.edu/lad/2005/09/index.html#162 I'm trying to use the same device, but strangeley enough, it doesn't even get recognized. Looking at both the kernel sources and at the alsa-driver sources, I see the following comment: ./sound/usb/usbquirks.h: /* TODO: add Edirol UA-101 support */ how did you guys make it work? Akos

[linux-audio-dev] Todays changes to "LADSPA2" strawman

by Steve Harris

http://plugin.org.uk/ladspa2/ Removed the :logarithmic hint, I agree with Paul, its not fit-for-purpose as specified. I'm now using the DOAP schema (http://usefulinc.com/doap) instead of Dublin Core for software information, much more appropriate. Fixed a load of typos in the schema and examples. Dave R. doxygen-ised the .h and added some text about choosing URIs. I removed the references to run_adding() (I think I got them all). - Steve

[linux-audio-dev] Re: [linux-audio-user] Re: First trip to Europe

by Dmitry Baikov

To close this thread for now. Thank you all for your kind and useful responces. However, it turned out that the main showstopper is visa. We can't get it for such a long time (a month), as it would be our first one. Things get even more complicated, since my girlfriend right now is not a student and does not have a job. They say we should build our "Shengen history" and after one-two (more - better) short and regular tours we can hope to get month-long visa anywhere we want. Taking this into account, we have to postpone our Trip to the next year and try to make two tours to shengen this year. It's a pity, since tours via travel agencies are about twice as expensive, but they are our only legal gates to europe. Moveover, the choice of the first place to visit is also restricted. We wanted to make London-Paris tour, but GB has very strict rules and rules us out. Possibly, it will be France and/or Italy as the most permissive ones. Will try to match our DreamTrip with the next LAC. Kind regards, Dmitry.

[linux-audio-dev] "LADSPA2" naming redux

by Steve Harris

Richard's preferred name of "PEA" (AKA anything that's not LADSPA2) got me to thinking. What about abstracting it up one level and calling the directory + .so files + manifest thing a POD (Plugin Object and Description). Theres nothing particularly audio specific about the high level construct, its "just" that we don't have a concrete ABI for dealing with sills, video etc. This means that what we think of as a "LADSPA2" plugin would be a "LADSPA POD". The directory would have a .pod extension. POD seems like a nice word to me, plenty of scope for puns, short and "pod plugin" on google doesn't come up with anything much. The only audio related things for "pod" I could see are: a guitar effects processor called a PODxt (there was a POD historically), an audio I/O device called a Firepod, and the documentation for the LADSPA Perl module. Perl docs are the only non-coincidental hits for "LADSPA POD". I could juggle the description stuff around the seperate pod-ness from ladspa-ness, it's not hard, but also not neccesary. There is a small name clash with Perl, which uses .pod for it's documentation format, but I dont think that's really an issue, our .pods will be found in POD_PATH (eg. /usr/lib/pod/, ~/.pod/) and be will be directories. Thoughts? - Steve

[linux-audio-dev] Re: NAB trade show

by Juhana Sadeharju

Anyone took photos at the show? Dieter Meier of Yello was in Avid's booth if I understood correctly. Dieter Meier is a member of board at Euphonix and perhaps now has business with Avid too. http://www.euphonix.com/news/news2002/021202_dieter_interview.htm A few guys at the Yello list visited the show but they had no camera with them. :-( Juhana -- http://music.columbia.edu/mailman/listinfo/linux-graphics-dev for developers of open source graphics software

The > ones that take in stereo and convert it to surround sound. The sales There are infinite ways to do this and none of them make the music sound better than stereo. OK I guess "better" is subjective but there's certainly no "correct" way to do it. You can easily derive a center/sub channel but most systems do something hideous when it comes to the rear channels. -Ben Loftis www.harrisonconsoles.com
