i remember i have read a statement about a lock free ringbuffer
implemented in C somewhere.
Can anybody remeber it ?

Hi all,
After the LAD Conference and using apps which used the lrdf taxoomy
(putting plugins into categories) code it became obvious the the current
taxonomy wasn't really useful.
the current taxnomy looks like:
Utilities
Generators
Oscillators
Simulators
Reverbs
Time
Delays
Phasers
Flangers
Chorus
Reverbs
Frequency
Measurement
Filters
Lowpass
Highpass
Bandpass
Combs
Allpass
EQs
Parametric
Multiband
Pitch shifters
Amplitude
Amplifiers
Waveshapers
Modulators
Distortions
Dynamics
Compressors
Expanders
Limiters
Gates
This makes a certian amount of sense from a theoretical point of view, but
isn't much use when you're trying to find a compressor.
So, we need to deine a taxonomy that is more useful to users.
I recon that something like this is a good start, but feedback would
really help:
Utilities
Generators
Oscillators
Delays
Phasers + Allpass
Flangers
Chorus
Reverbs
Filters
Lowpass
Highpass
Bandpass
Combs
EQs
Parametric
Multiband
Pitch shifters
Modulation
Distortion
Amp effects
Waveshapers
Dynamics
Compressors
Expanders
Limiters
Gates
Feel free to suggest changes to make it easier to use. I can drop in the
new taxonomy without changing any code. As soon as we decide on a new
structure I will distribute a new .rdfs file then you can just copy it
over the old one and try it out.

Greetings:
While helping out a client with his PlanetCCRMA installation I've
realized the intense need for session management software. I'll start
working with LADCCA, but I wondered if anyone else has been using it and
if they have any particularly useful experience to share yet. I realize
LADCCA is in its early stages of development, but this kind of software
could really reduce the amount of time we spend setting things up. Yes,
I know I can use scripts to help automate setup, but it would be great
to have a single piece of software to do that for me.
Just musing out loud here... ;)

At this time the /. effect is in full swing. The main page now reports
more than 10,000 reads, far more than any other article currently
listed. I feel that this is because it's really the time to notice Linux
audio. Linux audio development has 'way outstripped my expectations,
thanks to the enormous efforts from this really rather amazing
community, and as they say, "People are beginning to notice!". I know
there's so much work yet to be done, but it's a good time to acknowledge
the advances that have been made since 1999.
Also, I just received the May 2003 hard-copy issue of LJ with my
Softsynth Roundup in it. Once again the editors at LJ have done an
excellent job with the layout and presentation. For those of you who
will read the article please feel free to contact me with your comments
and/or complaints.

Demolition, my destruction testing tool for LADSPA plugins is now available
as a pre-release version. This is fully functional, but I want to get
some feedback from "users" (ie other LADSPA developers) before I call it
version 1.0
http://www.ecs.soton.ac.uk/~njl98r/code/ladspa/
(Don't be distracted by all the XMMS LADSPA stuff on the same page)
If you write LADSPA plugins, or if you maintain a LADSPA host and don't
think much of the quality of some plugins, this tool is for you. Please
run out and grab it. There is documentation linked from the same place
as the source code.
Now, at this point I could list a dozen or so bugs in famous LADSPA
plugin libraries, but I won't. If this tool works you should be able to
find them yourselves (all bugs are shallow...). I know Steve Harris
is already beavering away fixing the ones he's found in the swh-plugins.

Just a note to mention that the Karlsruhe report has had 3,871 reads
so far, more than any other article listed except for the Ultimate Linux
Box on-line project. Seems like maybe people are really interested in
what you guys are up to ! :)

AGNULA: Call for Python Volunteers
The AGNULA ("A GNU/Linux Audio Distribution") is working on the
creation of two entirely Free Software GNU/Linux distributions for
professional audio users based upon Debian GNU/Linux and RedHat.
Unfortunately, there is one application that depends on proprietary
Java implementations for its GUI, so at the current state it would not
be possible to include that package in a fully functional way.
That application is jMax, a visual programming environment for
building interactive musical and multimedia applications and a
contribution to AGNULA by IRCAM, the music center of the Centre
Pompidou in Paris, France.
The most likely solution of this problem seems the creation of a
Python-based Free Software GUI for jMax that can replace the current
Java GUI. Unfortunately IRCAM is lacking the people that could
complete this task and cannot do it without help.
So we are now looking for volunteers who are interested in helping
create a Python GUI for this remarkable application. Volunteers can
subscribe to the mailing list at
http://listes.ircam.fr/wws/info/jmax
to get in touch with the other developers working on jMax.
Although IRCAM cannot do the development all by themselves, they offer
priority support (response times within 24hrs during working days) to
everyone who'd like to help out.
If you'd like to find more information about the issues and what has
been tried to resolve them, that is available at
http://fsfeurope.org/projects/agnula/java.html.
If you were looking for interesting audio projects to get involved in,
this might be a good opportunity - all help will be appreciated!

"There's no free expression without control on the tools you use"
galan-0.3.0-test2 is released.
galan is a modular synthesizer featuring subpatches, event processing
logic and more.
LADSPA is supported.
you can build your own synthesizer interface, placing controls where you
want them.
I have ported the features added to the galan-0.2 branch up to the 0.3
branch.
- Lib directory is in place.
- liblrdf support.
- feedbacksafe delay added which enables you to have plugins in the
feedback path like in ams.
opengl does not work.
i have some troubles with the gtkglarea 1.99.0...
this caused me not to implement multiple jack output ports...
i have now given up on opengl and will add the multi outputs/inputs
next.
if you want opengl use galan-0.2... 0.2.15 will be released soon, when
the sheet library is updated and reorganized.

Has anyone seen this yet?

What's particularly interesting is that, according to some of the buzz I've
been hearing, their primary implemention platform is Linux (in an embedded
mode, I imagine). None of which is to say that it'll be Open, but this could
be a pretty kicking thing to have available.
Cheers!
