[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

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

[linux-audio-dev] CLAM Music Annotator 0.3.1 released

by Pau Arumi

May 8th 2006, CLAM Music Annotator 0.3.1 released What is the CLAM Music Annotator? --------------------------------- Is an application of the CLAM framework [1] that can be used to visualise, check and modify music information extracted from audio: low level features, note segmentation, chords, structure... The tool is intended to be useful for (though not limited to) the music information retrieval research whenever you need to: - Supervise and correct the results of automated audio feature extraction algorithms - Generate manually edited annotations of audio as training examples or ground truth for those algorithms. You can learn more about Music Annotator in its wiki page, which includes screenshots and videos galleries: http://iua-share.upf.es/wikis/clam/index.php/Music_Annotator The application comes with two example extractors. One that computes low level descriptors and another that performs chord detection. It also features useful views such as the "tonnetz" and "key space" to visualise the tonal features (chords, notes...) CLAM Music Annotator is GPL. What's new from last (0.2) version ? ------------------------------------ This is a major release which have at least duplicated the number of important features. - Ported to Qt4 - New chord extractor - Colourful animated visualisations - Improved application work-flow (project building, etc.) - It also works as a collaborative annotation tool (BOCA client) See the changelog [2] for a complete list of changes. or the wiki [3] for general information. How to install it? ------------------ In Windows we provide a binary installer which includes all the needed libraries (including Qt4) and ready-to-use sample data. For Linux and Mac OSX we don't provide binaries at this moment (though we plan to do in short). Source tarballs can be downloaded from the web and complete build instructions can be found in the INSTALL file. http://clam.iua.upf.edu/download.html Acknowledgements ----------------- This project is partially founded by SIMAC European Project, IST-507142 and Catalunya's Government, exp 200/05 ST The chord extractor extracts segments labeled with chords. It uses Christopher Harte algorithm with some minor variations. It has been developed as a collaboration between the Queen Mary University of London and the Universitat Pompeu Fabra (UPF) of Barcelona. The "keyspace" view is a great contribution of Jordi Bonada and Emilia Gomez, at UPF. The CLAM team Music Tecnology Group Universitat Pompeu Fabra (Barcelona) References: 1. http://clam.iua.upf.edu 2. http://iua-share.upf.es/wikis/clam/index.php/Music_Annotator_Changelog 3. http://iua-share.upf.es/wikis/clam/index.php/Music_Annotator

[linux-audio-dev] n00b friendly latency tester

by Lee Revell

After some discussions at LAC I think a user friendly latency tester is needed so users have an easy way to test a setup, something better than than just installing apps and being mystified when they get tons of xruns. The backend is trivial (there are a bunch of similar little tools out there), but I'm not a GUI person. Would anyone like to help design and implement this? Since time is money ;-) a simple Gnome and/or KDE front end would be the easiest way to start, and of course there should be a separation between the GUI and the back end so anyone can implement a leaner version if they want to. Anyone want to help with the GUI side? Lee

[linux-audio-dev] LAC2006 Photos

by Christoph Eckert

Hi all, I just uploaded some Photos taken during LAC 2006. It one huge tgz archive, no web gallery available. It will be up in 15 minutes: http://christeck.de/stuff/LAC2006.tar.gz To save bandwidth, I scaled them down a bit. If anyone is interested in a particular high resolution image, don't hesitate to send me an e-mail. Any further resources? Best regards ce
