Hello all, yada-yada (*)
The paper submission deadline for LAC2009 is just a little
more than 100 hours away, and the response so far has been
rather disappointing, to the point that there would not be
much of a conference at all.
The deadline could be extended by two weeks (29 Jan, midnight),
but that would make sense only if we know there will be
sufficient submissions.
So if you are planning to submit a paper, or present a
workshop please let me know *ASAP*, and in any case before
the original deadline (15 Jan, midnight).
Ciao,
(*) This means 'best wishes for 2009 !'

Greetings,
I hope this email finds everyone doing well.
The Southern California Linux Expo is fast approaching and we have a few
spots left for free & open source projects. I would like to formerly
invite the Linux Audio consortium to participate at the show and
showcase the various free & open source audio applications that are
currently available. The show will be taking place February 20th -
22nd, 2009 in Los Angeles, CA at the Westin LAX.
SCALE would provide a complimentary booth on our show floor including
all the usual amenities such as a 500W power outlet, ethernet drop, one
6' table and chairs. We will also provide 3-5 complimentary passes to
the show.
Ideally we would like to see as many of the Linux Audio member projects
represented. Any questions please do not hesitate to ask.
Thanks!
Gareth

Hi!
Is anyone planning on a complete DSSI (w/ GUI) version of amSynth or even
better, an LV2 version? I'd also be interested to hear if there is anything
similar already in the LV2-world?
- Jaakko
Aldrin is an open source modular music sequencer/tracker for the
GNU/Linux operating system. It is written in python and supported by
the Armstrong audio processing backend (previously known as libzzub).
Improvements in this release:
- All of the user interface elements reworked into a new component system
- Full undo/redo support
- Searchable plugin list browser
- Pattern editor zooming
- Improved LADSPA/DSSI support
Project sites:
http://code.google.com/p/aldrin-sequencer/http://code.google.com/p/armstrong/
Nightly builds for Ubuntu and Debian:
http://www.pohunek.free.fr/
Is there a way to check from the command line the audio length (not the
size of the file) of an audio file (assume wav, but I also want to do
other types, especially flac). So far I have only found this:
sox myaudiofile.wav -n stat
which gives me more information than I need, but at least I can parse
out the length from that output. Is there a simpler more direct
approach using some other command line utility ?
Bill
Hi again!
The csound utility is called sndinfo, but it also gives more than you need.
I know that the sndfile-* and eca* utilities can handle quite a collection
of formats .flac definitely included.
Kindest regards

Announcing the DSSI Soft Synth Interface version 1.0 release:
http://dssi.sourceforge.net/
DSSI is an audio plugin API for software instruments and effects,
based on LADSPA, the ALSA sequencer event types, and OSC (Open
Sound Control) communications.
DSSI is now supported by six full-featured hosts, several
specialized hosts, and at least twenty-two DSSI plugins. (See the
above URL for a list.)
This release contains one small addition to the DSSI API itself,
allowing for communication of the sample rate to DSSI UIs. Since the
DSSI API has been stable now (with minor additions) for four and a
half years, and since most active interest in further extending a
Linux softsynth plugin standard has been absorbed by the LV2
project, it seems appropriate to call this release "version 1.0".
In addition to the API addition, code and documentation updates have
been made in the DSSI release itself, and in FluidSynth-DSSI,
hexter, and Xsynth-DSSI. New versions of each are available at the
above URL. Specific changes include:
DSSI 1.0.0:
* Addition to API of the new 'sample-rate' OSC method.
* Addition of a Karplus-Strong example synth.
* Documentation improvements.
* Updates for newer gcc/glibc, for Mac OS X, and for newer JACK.
* Addition of man pages thanks to Mark Hymers and Debian.
FluidSynth-DSSI 1.0.0:
* Fixed a bug that caused distorted sound when hosted by Aldrin.
* Updates for Mac OS X.
* Changed GUI to handle (ignore) the 'sample-rate' method.
* Added '-test' option to allow testing the GUI without a host.
hexter 0.6.2:
* Updates for newer GTK+.
* Changed GUI to handle (ignore) the 'sample-rate' method.
Xsynth-DSSI 0.9.2:
* Updates for newer gcc/glibc, RPM-based distros, Mac OS X, and
newer GTK+.
* Changed GUI to handle (ignore) the 'sample-rate' method.
* Added '-test' option to allow testing the GUI without a host.
Enjoy!

Hi
I recently update my debian glibc to 2.8.1, and surprise ... GTK based apps can't connect to jackd server, well even Ardour can't start the server,
maybe is a debian glibc/gtk issue, or maybe not .... can anyone check and confirm in other distro? btw qt, fltk jack based apps run fine, and other GTK stuff run.

Hi all,
Many thanks for your replies. Audacity and Traverso are certaintly
well-established projects, so I think I could learn a lot from them. I also
spoke previously (about a year ago now) with Remon from Traverso, who kindly
invited me to join so perhaps that could be an option too. I'm very keen to
learn about how audio software works so hopefully this will be the start of
my learning. Slightly off the topic...has anybody been having issues with
the new pulseaudio server in Ubuntu Intrepid? I tried one of the fixes
suggested on the forums (reverting to esound) but it still crashes
sometimes. It's annoying me now, the previous version was fine!
Thanks,
Daire
