A maybe silly question: where on a typical system are the rdf
descriptions of ladspa plugins supposed to live ?
I can't find them !

Follie! Follie! Delirio vano e' questo!
Hi,
I've recently began trying to write a jack-enabled audio app, and have
what's maybe a basic question...
From what I can tell, jack has a single global sampling rate, and all
clients are required to send and recieve at this rate. Is this correct?
If so, are there standard tools/libs to do on-the-fly resampling? I'd
like to have a client get a downsampled signal without having to
implement my own anti-aliasing filter inside it. Even if there's not
something to do the resampling for me, it would be neat if one client
could do resampling and others that want the data could connect and get
it... is it possible?
thanks,
Ken
Hello, all!
Me and my girlfriend are planning a trip to Europe for a month between
May and June.
It will be our first trip abroad, so please help if you can with a good advice.
Since it's not so easy to get out of here (russia), and I can't visit
all that great & numerous openlab's etc., one of the main goals is
"community building":
I'd like to meet (at least some of ) you, LADs/LAUs, in person.
Current plan is (yes, it's huge):
Moscow
St.Petersurg
--
Helsinki
Stockholm
Berlin
Koeln
Brussels
London
Paris
Bourdeaux
Madrid
Barcelona,Figeras
Genova
Milan?
Rome
Venice
Vienna
Prague

Moscow
There are two main questions
(lonelyplanet.com helps a bit, but residents can say much more):
1) what is the cheapest way to travel inside europe?
Bus? Airplane? If it's by air, how can we buy cheapest tickets? Which
company? How much days before the flight? etc. Or may be hitchhiking?
2) how hard is to find cheap place to sleep?
AND
Where can we meet YOU?
Sorry, we don't know exact dates as we are researching on european
visa (trip begins from Helsinki, since it seems the easiest way to get
into europe).
Sincerely,
Dmitry.
Kaiku. It is unfinished. I'm stuck. A lot of help needed! Don't use
seriously. Not all important controls are in GUI.
http://www.funet.fi/~kouhia/kaiku20060418.tar.gz
Kaiku is now GVerb plus multitap, but will improve to different
structure which I have already designed. I will complete the reverb
code if the problems will be fixed.
(1) Need better GUI. Control envelopes on time-axis for
a few features. GTK2 and/or OpenGL. We discussed about the
great amount of callbacks used in my GTK code years ago but
I did learn nothing ;-)
(2) Preset system. XML files.
(3) How to run a Jack application in an editor as a non-realtime
plugin?
(4) Kaiku should start as unconnected Jack application.
Or connected to Alsa or Jack ports given as command line options.
(5) My computer is only barely running Kaiku in realtime, and that
after I reduced the multitap delay complexity. I have not taken
speed-ups from LADSPA-GVerb.
Uh oh. The code has unused old code as well. Some experimental GUI
stuff. Ignore them.
I only would like to have a Lexicon quality reverb. Designing
and coding such a reverb is a huge task, and it won't help if
I spend years with basic software engineering tasks which any
Joe programmer could complete easily. My private Lexiclone
has several algorithms of which only GVerb has been turned to
open source within four years.
I'm not a reverb designer or DSP engineer either, and I'm not
sure do I want be one. I started figuring out the reverb business
with zero DSP knowledge, and only because we did not have
a quality reverb -- I wanted to change the situation.
Could we collect $$$$$ of money and hire Dattorro or any other
qualified effect guru to design quality open source effects for
us? Blender was purchased for $100,000, right?

for developers of open source graphics software
At Q2S [1] there are currently vacant scholarships for Ph.D. students,
and open positions for Postdocs and visiting scholars.
The audio group at Q2S has an interest in Linux audio. For our work we
have developed software for low latency streaming of audio over IP
networks [2], and an encoder/decoder for seventh order Ambisonics in the
horizontal plane. We work within audio over IP, sound fields, audio
coding, error concealment and related fields [3]. There is also a
multimedia group, with which we cooperate closely.
A person with in depth knowledge of and experience from Linux audio
development and use, ALSA, JACK and related topics might be a welcome
addition to the audio group. If you are such a person, and would like
to use your talents in an academic research setting, you are encouraged
to contact us.
Information on the open positions:
http://www.q2s.ntnu.no/vacant/dring-en.phphttp://www.q2s.ntnu.no/vacant/postdoc-en.php
The formal deadline for application was march 24th, but later applicants
will also be considered.
For further informations, these may be contacted:

netjack-0.11
------------
Warp your jack ports over an IP network. Also have Transport synced
between 2 machines.
Work is underway in improving the latency for big channel counts,
like 24in / 24out. There seems to be a bottleneck in the kernels
handling of big UDP Packets.
However netjack seems solid with a period size of 128 and a roundtrip
latency of 3 periods. (this is at 24/24 float on 100Mbit) The latency
does not seem to improve with Gbit.
Also featuring:
- improved error messages.
- some AutoConfig on the slave side. (only period and samplerate)
- alsa_in and _out improvements.
Have Fun.

Thats an insanely large project you are proposing. :-)
Hacking snd into ardour should only require a days work or
something because snd can be compiled as a gtk widget.

Yeah, that makes sense. However, it would be very nice to have snd as a
widget in ardour to edit single soundfiles. If you add some guile
functions in ardour to update the graphs in the multitracker waveforms
views as well, one could edit in snd (inside ardour somewhere) and
immediately see changes in the multitracker view.
A second release of the Ambisonics plugins is now available.
* Added cube (8-speaker) decoder.
* Removed conflicting port hints.
