Hallo,
as it was quite helpful last year I now again opened up a page on my
WikiWeb for people who might want to share their ride to the Linux
Audio Conference 2 next weekend in Karlsruhe. You can find, read and
edit that page here:
http://footils.org/cms/pydiddy/wiki/LaConf2
Everyone is allowed to edit this page, wiki-style. If you can offer a
ride in a car or if you are looking for a lift yourself, you can leave
your contact information there. This also can be used to form groups
to get train discounts or similar.
Ciao

For a newbie (someone who hasn't even installed a distro yet) I
would suggest doing a Live CD first (Dynebolic is the most mature for
multimedia, however the Agnula guys currently have one just about ready
to go). Once the Linux newcomer has gotten an idea of what you can do
(and more importantly what they want to do) with linux using the Live
cd, they can then start to look at distros.
The live CD route has a couple of advantages. First, if they
find they don't like Linux, all they need to do is reboot. No pain, no
hassle, nothing. Second, the live CD's are a great way to gradually
learn all of the ancillary stuff you need to know if you are going to
use linux (command line stuff, configuring programs, directory structure
(like: what is your home directory?), etc.) The problem with going the
straight Distro route (except I think for CCRMA which seems to get
everyone who tries it up and running VERY VERY fast) is that you are hit
with all of this 'new' info right at the onset. It can be a bit
overwhelming, and a live cd really helps to acclimate a new user to the
wonderful world of Linux.

Hi Martin,
Another mailinglist worth posting is music-dsp:
http://music.calarts.edu/~glmrboy/musicdsp/music-dsp.html
There you may often meet Angelo Farina, who has made available an amazing
quantity of publications about Room Acoustics among other fields:
http://pcfarina.eng.unipr.it/Public/Papers/list_pub.htm
For your concern, let me quote the following one:
"APLODSP, design of customizable Audio Processor for LOudspeaker system
compensation by DSP", 109th AES Audio Convention, Los Angeles, 18-22 September 2000,
http://www.ramsete.com/Public/Papers/147-AES00.PDF
When it comes to Linux, you may already know the "Sound & MIDI Software For
Linux" ressource site, which contains the following sections:
- DSP Software: http://linux-sound.org/dsp.html
- Scopes: http://linux-sound.org/scopes.html
Not featured there for the moment, JAAA (the Jack and Alsa Audio Analyser), by
Fons Adriaensen, will be presented at the 2nd International Linux Audio
Conference, 29 April - 2 May 2004, ZKM Center:
http://users.skynet.be/solaris/linuxaudio/http://on1.zkm.de/zkm/stories/storyReader$3625#abstract_adriaensen02
If you want ISO-normalized linear or logarithmic swept sines, have your own
series burnt with Reference Audio CD:
http://refacd.sourceforge.net/
There are other techniques worth-using when it comes to getting room impulse
responses, especially one based on MLS sequences, most of which you'll have
compared on this document:
"Comparison of different impulse response measurement techniques", G.-B. Stan,
J.-J. Embrechts, D. Archambeau, Journal of the Audio Engineering Society, Vol.
50 (2002), n°4, pp. 249-262,
http://www.montefiore.ulg.ac.be/~stan/ArticleJAES.pdf
You can at last also check my Mozilla-generated bookmarks page, where you'll
find most of the above, bearing in mind it is frequently subject to change:
http://theremin.free.fr/hunchback/index.php?nodes=|0|1|50|
This points you to the following nodes (remove the last prefix of the url in
case of malfunction):
+ ArkaKlap
+ Kontenu
+ Kode (Dev Ressources)
+ Kours (Papers)
+ Koncurrence (Soft- & Hardware Ressources)
I'll try to make Octave m-files (an opensource 95% Matlab clone) available by
the end of May: MLS / swept sine generation, impulse response extraction,
inverse filtering...

It's me again with some config issues..
After getting my soundcard (Terratec DMX 6 Fire) to work correctly with
Audacity, i decided to use Muse... So i installed Jack.
But when i do jackd and it creates the alsa driver, it puts 0 and 0 for number
of input and output channels. When i try to force it into something else with
-i 6 and -o 2 for example, it tells me "ALSA:cannot set channel count to 6
for capture".
Within Audacity, i can set the number of recording channels to whatever i want
and they all record properly so i'm a bit surprised why it doesn't work with
jackd... Any idea? Any help would be very much appreciated as i've been
reading various FAQ/help pages on various sites but haven't found any answer
yet...
Have a box I have just put MDK 10.0 Community on.
Shuttle A39k Mobo, Athalon XP 2600, 512MB, Via chipset...Shows realtek
chip on soundcard in Alsa mixer.
Have installed Thacs 2.6.5 MM kernel, modprobed "realtime allcaps=1"
manually. Installed the regular set of apps also from Thacs recently
updated page for 10.0;
Qjackctl
Jackit .98
Ardour most recent
etc,etc,etc.
I can get Jack to fire up no problems but the Xrun callbacks run like
crazy! It seems to do it only on the playback side of the duplex I/O.
(tested in options of Qjackctl) Does not appear to do it on Capture.
Ardour connects as client etc. Seems fine although I've not tried to
record anything yet. Just realized that the only thing I have not set up
is "tmpfs" although I did on the last install with the exact same setup
and it still did the same thing.
Any ideas??
Thanks
Just in case I ain't said it lately, This Linux community is the
GREATEST~~~ ;)
Anouncing version 0.6.0 of FreqTweak.
http://freqtweak.sourceforge.net
New in this release are spectral filter Modulators, which can animate
and modulate any of the filters automatically in several ways.
If you thought FreqTweak was fun before, be prepared for hours of
audio mayhem. See the webpage (and the software) for details.
Just in time for the ZKM/LAD conference in Karlsruhe :)
Please report any problems compiling this release on your various
platforms to me, and as always report any bugs or feature requests to
freqtweak-user(a)lists.sourceforge.net (you must subscribe first).
Enjoy,
Jesse Chappell
------
FreqTweak is a JACK-based application for FFT-based realtime audio spectral
manipulation and display. It provides several algorithms forprocessing audio
data in the frequency domain and a highly interactive GUI to manipulate the
associated filters for each. It also provides high-resolution spectral
displays in the form of scrolling-raster spectrograms and energy vs
frequency plots displaying both pre- and post-processed spectra.

hello,
i am trying to record impulse responses from
my studioequipment to correct it's phase and freq responses
with e.g. DRC and bruteFIR.
I heard the best idea would be to take log sine sweeps
for the measuring?
it would be great if someone more experienced than me
knows of a good method to create sweeps (or chirps) of equal
freq.response with linux software?!
or maybe some other tips and tricks about audio impulse response
measuring with linux?
peace

Hi guys,
I was wondering if someone could recommend a good way of recording RealAudio streams so that they ultimately end up on disk as .wav or .mp3 or .ogg files.
I looked at Jack, but RealPlay isn't listed as one of Jack's compatible applications.
I looked for a RealPlay plugin for XMMS (someone said he used that plugin and XMMS's Disk Writer plugin), but I couldn't find it anyway.
Any help would be most appreciated.
Thanks,
Christian
Hi,
as the onboard soundchip on my Epox 8RDA3+ (CMedia 9739) doesn't work
very well, I'm looking for a cheap soundcard which can handle 5.1 sound.
It should run under Linux (Debian Sarge, Kernel 2.6) and Win98, and I
want to be able to play AC3 sound (that can be done in software, right?).
I've already looked around and found several cheap 5.1 cards, but I have
doubts about their Linux compatibility... Can you tell me something
about these cards:
Creative Soundblaster 4.1 Digital
Creative Soundblaster live 5.1 Digital
Typhoon Acoustic Six 5+1
Terratec Aureon 5.1 Fun
Is any of these cards well supported by Alsa, and can I play 5.1 and AC3
sound with it? I've already nearly decided for the SB live 5.1 Digital
but then noticed that it's not that well supported...
Or is there any other card which you could recommend? I don't want to
spend too much, it should definitely stay below 50 EUR, but I don't have
high expectations (playing MP3s and games, watching movies, getting
system sounds...).
Thanks in advance for your help,
Oliver Gerlich
