EASE looks exactly like what I'm looking for. But, at $800US it's
well out of my price range. Bummer.
Thanks for the tips....

I've been trying to find a simulator for room acoustics which
will allow me to construct a non-rectangular shaped room,
specify absorptive characteristics of the surfaces, specify
sound sources, and listening position. I'd like the output of
the software to be an impulse response, so that I can listen to
the predicted response, and some depiction of the standing waves
versus frequencies. Does anything like that exist for Linux?
For what it's worth, web searches lead me to some rudimentary
software to show room modes of rectangular box shaped rooms,
and there is a lot of theory out there too. But, the finished
"product" software seems scarce, or at least hard for me to find.
Thanks....

As far as i knew, it was not possible to any kernel hacker to build a

Texto traducido de forma automática:
sidux als Audio Workstation 1.) Der rt-Kernel Um sidux als
Realtime-Audio-Studio zu verwenden, ist ein Kernel mit
Realtime-Preemtion, ein rt-Kernel, erforderlich. Daran arbeitet Ingo
Molnar mit seinem rt-Patch. viele der Funktionen aus diesem Patch
sind inzwischen Teil des offiziellen Linux-Kernels. Doch leider ist
noch nicht alles integriert, so dass auch weiterhin ein Patch
erforderlich ist. Für Interessierte:
http://kernel.org/pub/linux/kernel/projects/rt/∞ Einen fertigen
rt-Kernel für sidux gibt es auf:
http://maledivenhilfe.com/makke/kernel/∞ Dort sind die jeweilig
aktuellen slh-Kernel + rt-Patch, gepatcht und gepackt von makke
(Danke makke). 2.) Die Konfiguration Um die Realtime-Preemtion als
User zu nutzen, muss die Datei /etc/security/limits.conf (als root)
editiert werden: @audio - rtprio 90 @audio - nice -5 @audio - memlock
750000 Dieser Eintrag gibt den Mitgliedern der Gruppe "audio" das
Recht Anwendungen mit rt-Priorität zu starten (die höchste ist 99 und
sollte irq's (Timer,Soundkarte...) vorbehalten bleiben). Der
nice-level wird um 5 erhöht (bzw. erniedrigt, also nicer) und 750MB
Speicher können von der Anwendung "geblockt" werden (d.h. er steht
exklusiv für die Anwendung zur Verfügung). Diesen Wert solltest du
deiner Hardware anpassen! Der aktuell eingestellte memlock-Wert kann
mit dem Befehl ulimit -l auslesen werden. Außerdem musst du natürlich
Mitglied in der Gruppe "audio" sein, was du per default bei sidux
bist. Das kannst du mit dem Befehl id überprüfen. Es ist auch möglich
hier statt der Grupe audio direkt einem User die rt-rechte
einzuräumen, wenn du statt audio den usernamen einträgst. PAM muß neu
gestartet werden damit die Einstellungen wirksam werden. do you want
more ?
Sidux as audio workstation
1) The rt-kernel
To sidux as real-time audio studio, is a kernel with real-time
Preemtion, a rt-kernel. That works Ingo Molnar with his rt-patch.
Many of the features in this patch are now part of the official Linux
kernel. But unfortunately, not all integrated, so that remains a
patch is necessary.
For those interested:
Http://kernel.org/pub/linux/kernel/projects/rt/ ∞
A final rt-kernel for sidux are:
Http://maledivenhilfe.com/makke/kernel/ ∞
There are the respective current slh kernel + rt-patch, patch and
gripped by makke (Thanks makke).
2) The configuration
To view the real-time Preemtion as user to use, the file / etc /
security / limits.conf (as root) edited:
@ Audio - rtprio 90
@ Audio - nice -5
@ Audio - memlock 750000
This article gives the members of the group "audio" applications with
the right rt priority to start (the highest is 99 and should irq's
(timer, sound card ...) reserved). The nice-level will increase by 5
(or humiliated, so nicer), and 750MB memory from the application
can "block" (ie he is exclusively for the application available).
This value should you adapt your hardware! The current set memlock
value can be created with the command ulimit-l read.
In addition, you must of course a member of the group "audio", which
by default when you sidux are. What you can use the command id. It is
also possible here instead of the Grupe audio directly to a user
rt-right should, if you place the user audio appearance. PAM has to
be restarted for the settings to take effect.
................
http://maledivenhilfe.com/makke/kernel/experimental/linux-sidux-2.6_2.6.24-…
* Added -rt3-patch
* Removed unionfs (still no support)
* -rt3 already includes:
- 2.6.24.3_NET_add-if_addrlabel.h-to-sanitized-headers.diff
-
2.6.24.3_x86-move-out-tick_nohz_stop_sched_tick-call-from-the-loop.patch
As far as I know, this kernel will not work into a Live CD because it
does not uses unionfs, but maybe it uses aufs.

I've been using lots of LADSPA plug-ins with many GNU/Linux applications.
(by the way it's been sometime that i gave up using any windows applications
in my home studio)
When it was with windows i tried too many high quality VST plug-ins like
URS, McDSP and etc.
These plug-ins engaged that they simulated some analog systems like SSL,
Neve and others.
I wonder,
1) Is that really true ? Can they really do it ? if they can how far can
they ?
2) They are really expensive software. Is that because they are paying to
the consumers of the analog products for the algorithms of their system's
simulation ?
3) What about the LADSPA plug-ins like CAPS, TAPS ? They really work great i
guess. At least they satisfy my needs. Especially with TAPS reverb i liked
it very much.
Thanks.

After quite some time, and reading between the lines of various posts on this list, I think I have finally understood how the qjackctl patchbay works and what it is for. Because of this, I have written a brief guide to using the patchbay but I have nowhere I can usefully host it. If anyone who knows what they are talking about would like to check my attempt for mistakes and/or can host the file, I would be more than happy to release it into the wild. I would be really pleased if this could happen and it turned out to be useful to someone as I have found the information on this list to be exceedingly helpful in my quest to make amusing noises at home.
Cheers,

All,
I'm trying the list one more time in the hopes that someone might have
missed this the first time...
I've been attempting to compile a .deb kernel that has these
attributes (patches/modules):
* rt-preempt
* squashfs
* aufs
...and have failed miserably, many many times. I'm hoping that some
of the liveCD devs on this list might have one already done that they
could share with me. If you do, please let me know.
Again, *very* sorry for posting this a second time, I'm just desperate. :)

ups, yes libgraphviz3 have leave sid. I build libflowcanvas0 new against
libgraphviz4 (it's the current version in sid, I dont realease it because I
have both versions installed). It will work now with libgraphviz4 sorry.
Please load it down again.
Thank's for make me Note it. Hope everything work well now.
For your other question, yes, if the package with the same or higher
versionnumber hit sid, it will replase the own build package.

Hi
I'm gonna play live with my electronica project, and now I'm looking for
some software that'll allow me to playback all the stuff the band can't
do in a more dynamic way than using mp3-files...
A few examples of what the music sounds like:
http://modlys.dk/holde_pkt.mp3http://modlys.dk/du_er.mp3
The band consists of
* Laptop
* Keyboards
* Upright Bass
* Vocals
I'm playing keyboards as much as possible. Hopefully the laptop will be
controlled by someone else, otherwise that's me as well.
Initially I planned on doing the tracks in chuck. That'd allow nice
dynamic things like turn-a-knob and the tracks gets more sparse and
other algoritmic stuff with randomness going on. I did alot of chucking
(not livecoding) and implemented some tests that suggests that this is
works very well but it tedious to program, difficult to control live
(which is the main problem) and a bit risky (that's how I feel at least)
in a live setting.
Another option would be freewheelin. That's not nearly as dynamic, but
might be a lot easier to control and should be much more stable.
What other options are there?
I've never used ableton live (I only run linux), but everybody who's not
running linux is raving about it and I guess that could do it. So the
last solution could be to run that somehow (through wine or wmware).
Oh, and one final thing. I once say someone using the lemur
(http://www.jazzmutant.com/lemur_overview.php) which I unfortunately
cannot afford. But with a lemur I feel I could use chuck controlled by
osc. So thinking in those directions (controllers) what options are
there that'll 1) allow me to grab/press a knob *and* 2) have visual
feedback (like "pressing this button will take you to the C-part" *and*
3) work with linux.
