aye, if you'd like to play with it, it's in an arch repository at:
http://www.metadecks.org/arch/
The library dependencies etc. were described in this email (which
references Erik's libsndfile--hack branch):

Hi,
I'm looking for a convenient wrapper library for ogg vorbis, because
what I've found on the xiph.org pages looks a little overengineered to
me.
I've used libsndfile most of the time, so this is the API Style that
I'd prefer, basically I need 4 functions I believe:
what_samplerate_are_you( vorbis_file );
how_long_are_you( vorbis_file );
seek_to_position( vorbis_file, 23456 );
read_data( vorbis_file, buffer );
libvorbis and libogg however have to interact in some obscure way and
I honestly don't want to waste my time reinventing the wheel, while I
could be hacking on a new asskicking application ;)

Hello administrators, hello list members,
for my research for a lecture I will be holding on opensource and audio
in October in Stuttgart the following informations would be very
interesting:
How many people are subscribed to the lau / lad -lists. How many
participate actively ? Is it possible to roughly estimate, where they
are from (Amerika, US, Asia, part of Europe, Germany).
Is anybody capable of providing those informations? Thank you very much,
Michael
2.6.13.1-rt6, rlimits-patched pam and configured thus:
# in /etc/security/limits.conf
* - rt_priority 0
* - nice 0
@audio - rt_priority 50
@audio - nice -10
jack starts happily with realtime enabled, and the xruns are very few.
But no jack application will start, they all give this error:
jack_create_thread: error -1 switching current thread to rt for
inheritance: Unknown error 4294967295
It's like the ol' jack is root apps can't connect days, but I thought
rtlimits was supposed to make it possible for a user to get rt_priority.
Am I missing something?
Ah! It came to me just now - I set the priority field in qjackctl to 0
instead of 1 (where it was) and now jack apps can start. Heads up there.
Maybe applications need a way to recognize what rt_priority level to ask
for based on what jack is running at? On a tangent, how exactly does
that work? Is rt_priority=0 sufficiently prioritized? (because it is the
only thing running realtime)

Did you find anything?
I just started browsing
http://www.opendx.org
which should be open source. It is a modular visualization
system. Don't know if it helps but the gallery looks advanced.
I have a problem in checking out the CVS, though.

Hi!
I wonder if someone could provide me with the right hint, for I feel it is
not much to get me where I want.
I have an old suse system (gcc3.2 glibc 2.2.5), now I wanted to install a
newer gcc (3.4.3). It compiled fine and I can compile other programs with it.
Yet there is - apparently - some configuration problem. For if I start
linuxsampler or ecasound compiled with new gcc it says, it has a problem with
libgcc_s.so.1. It can't find some symbol VERSION_3_3 or something to that
effect. I tried ldd on those programs and it told me that they contain both
libgcc_s.so.1 from /lib and /usr/local/gcc343/lib. What am I doing wrong. For
I know this can work fine.
I recompiled my libstdc++ (from the 3.4.3 package) with my already installed
compiler to prevent it from including the old libgcc_s, but no effect.
What can I do? Should I put the new library-paths at a specific point in my
/etc/ld.so.conf? Set some special environment variable?
Any help is GREATLY APPRECIATED!
Kindest regards
Julien

Any help would be appreciated.
Does anyone know of a tool especially useful for visualizing room
impulse response measurements? Magnitude responses, waterfall plots and
such.
I'd prefer something more efficient and quicker to work with than octave
and gnuplot.

Full-duplex I/O with a minimal number of intervening buffers required (i.e.
very low throughput latency), preferably accessed through a callback
interface like JACK's. Last time I tried this it was quite complicated.
Maybe this has gotten easier in the last 2 years, but the docs don't seem to
be any different.

First release.
Sorry for the clanlib dependency, but it's what I could do quickly.
You'll possibly need to point the makefile in the right place. A
build system will appear some day.
