Julien,
I react with some delay, but I listened to this piece very early this
morning. Everything was quiet in the house. I had the headphones and was
very concentrated on it.
It *really* moved me.
This is the second piece I ear from you. With the same pleasure (not
that I want to put too much pressure on you :-) )
Thanks a lot.

I'm using a RME card for audio and MIDI and two Envy24 cards for MIDI.
Using rtirq with it's default in /etc/rtirq.conf,
resp. /etc/default/rtirq resp. /etc/sysconfig/rtirq
RTIRQ_NAME_LIST="rtc snd usb i8042"
caused
PID CLS RTPRIO NI PRI %CPU STAT COMMAND
55 FF 90 - 130 0.0 S irq/8-rtc0
659 FF 85 - 125 0.0 S irq/20-ICE1712
671 FF 85 - 125 0.0 S irq/21-ICE1712
652 FF 83 - 123 0.1 S irq/18-hdspm
switching to
RTIRQ_NAME_LIST="rtc hdspm snd usb i8042"
resulted in
PID CLS RTPRIO NI PRI %CPU STAT COMMAND
55 FF 90 - 130 0.0 S irq/8-rtc0
619 FF 85 - 125 0.1 S irq/18-hdspm
629 FF 80 - 120 0.0 S irq/20-ICE1712
631 FF 80 - 120 0.0 S irq/21-ICE1712
Dunno, perhaps RTIRQ_NON_THREADED="rtc snd" should also be edited.
Anyway, thanks to coincidence I noticed this issue and thanks to Rui I
was able to correct the priority.
My intend is to inform users of several PCI, PCIe MIDInterfaces to take
care about priorities, when one of the devices additionally is used for
audio too.
I didn't test if there's an audible difference on my machine, I suspect
that there isn't any difference, but IMO even this could be the cause
for an issue.
FWIW, I also own an USB MIDI device, a nice addition for non-rt bulk
dump, for my needs useless to make music.
I guess if I wouldn't use those Envy24 cards as MIDInterfaces, the RME
would have first priority after the clock.

Dear List,
forwarding this job posting, as people on this list could be interested:
best, P
------------------------------------------------------------------------
Job posted by Institute of Electronic Music and Acoustics/ University of
Music and Performing Arts Graz (23/11/2011)
PhD student in Sonification Research (Audio Engineering/ Climate Science)
Applications are invited for a postgraduate student to join the
Institute for Electronic Music and Acoustics (IEM, http://iem.kug.ac.at)
at the University of Music and Performing Arts Graz for the FWF funded
project SysSon – A systematic procedure to develop sonifications.
The goal of SysSon is the systematic development of sonifications - from
finding sound metaphors and creating a ‘sound library’ to aesthetic/
scientific evaluation and finally the sonification tool ‘ClAudio-Climate
Audio’. The procedure is developed with and tested on data from Climate
Science. Main researchers of the project (and supervisors of the PhD)
are R. Höldrich and K. Vogt at IEM, where the PhD student will be based.
Cooperation partners are the Wegener Center for Climate and Global
Change (www.wegcenter.at) and the Center for Systematic Musicology
(www.uni-graz.at/en/muwi99ww).
The PhD will comprise the application of the procedure to data from
climate science: handling data compatibility issues, sound synthesis,
co-development of evaluation test design, finalizing of ClAudio, and
supporting of sound installation.
The position is available from 1st February 2012 and financial support
is guaranteed for 2 1⁄2 years (an additional half year of support for
writing up the thesis is envisaged). Salary will be paid according to
www.fwf.ac.at („Personalkostensätze“ – „DoktorandIn“).
The closing date for applications is 25th December 2011. (Skype)
interviews are planned for January. Female applicants are preferentially
considered in case of equal qualification.
We expect:
+ A Master’s degree in audio engineering and electrical engineering or
computer science or similar, who have a solid scientific background in
acoustics, sound synthesis and auditory perception. An additional
background in sciences (physics/ climate science) is beneficial.
Candidates about to earn their degree are welcome to apply.
+ Familiarity with programming languages (either SuperCollider3 or Pure
Data; plus other programs such as Max MSP, MATLAB, etc.) is a precondition.
+ High motivation for interdisciplinary and application-oriented work
and a special interest for sonification research.
+ An integrative and cooperative personality.
+ Very good communication skills in English.
We offer:
+ A top-level research environment at the edge of technology and the
arts; the IEM is considered to be Austria’s leading research institution
in the field of audio engineering with the three research areas Artistic
Research, Signal Processing and Acoustics, and Computer Music (including
sonification).
+ Efficient supervision by an interdisciplinary team of supervisors,
strong communication and interaction between the involved institutions.
+ The location in Graz – a city of five universities (two are involved
in SysSon) and cultural capital of Europe 2003, hosting internationally
renowned festivals such as steirischer herbst and Elevate.
Please send your applications (in English or German) to vogt(at)iem.at
including:
+ letter of motivation or résumé
+ CV
+ copy of relevant university diplomas
+ a short exposé (1-2 pages) on a previous project related to audio
engineering, sonification or similar
(sound examples –or their links- are welcome)
hi all
i'm looking for a simple app (gui or command line) that can simply generate
a single midi message. I would like to be able to feed all data into it
and then press the 'send-midi-message-button' ;-)
the goal is to send midi messages to an external hardware audio FX unit
(that has a midi input) to select a specific program on that unit
any suggestions ?
grtz

Hi,
we'd like to ask those who are interested in the new Guitarix LADSPA
plugins to run them on their systems and give us some feedback. They
do fine on our own machines and seem to be fit for wider testing.
The plugins "Guitarix Amp" and "Guitarix Stereo Fx" wrap all of the
entire sound engine of Guitarix. You can load a preset that you defined
with the Guitarix program, and even define some parameters for DAW
automation.
It's explained in our wiki:
https://sourceforge.net/apps/mediawiki/guitarix/index.php?title=How_to_use_…
Our SVN:
svn co http://guitarix.svn.sourceforge.net/svnroot/guitarix/trunk guitarix
After checkout, build with
./waf configure && ./waf && sudo ./waf install
for an installation to /usr/local.
Our tracker:
http://sourceforge.net/tracker/?group_id=236234
Your feedback will be welcome here or there or anywhere..
Or in our forum:
http://sourceforge.net/apps/phpbb/guitarix/
so please, don't be shy and tell us your test results or
if you think the concept is usable / unusable :-)
ciao

Hi,
Just wanting to know what people are doing for RT audio on Arch Linux?
Have got a bit out of the loop on these matters.
Not entirely sure what I had configured before... Think it was just
the standard kernel, but since 3.1 (possibly) (or a couple of weeks
ago) I'm informed that "JACK is running in realtime mode, but you are
not allowed to use realtime scheduling."
Any help appreciated.

Thanks a *lot* for this. Creating a package on a machine that doesn't
already have lv2core installed will be *much* easier.

I'm trying to use mplayer to play a video made on my G2 Android.
The sound does like two choppy samples of 250ms each and then stops. The video plays for a few seconds then locks up, no matter how long the video is.
If I play it with -nosound, the video plays fine (if a little slow). But with sound, it's no dice.
ffmpeg -i says the following about it:
[mov,mp4,m4a,3gp,3g2,mj2 @ 0xb7ecf680]edit list not starting at 0, a/v desync might occur, patch welcome
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'VID_20111121_111728.m4v':
Duration: 00:01:14.56, start: 0.000000, bitrate: 5930 kb/s
Stream #0.0(eng): Audio: libfaad, 32000 Hz, stereo
Stream #0.1(eng): Video: h264, yuv420p, 1280x720, 90000.00 tb(r)
So, hmm. What's this 90000.00 tb(r) about? Everything else seems to make sense to me, 5.930Mb/s bitrate, theh audio and video codecs, etc.
Any idea how I can get mplayer (an admittedly old version) to play it?

Probably not the greatest display of what you can do with a linux box
this, but we just released two albums and an ep yesterday. The albums
are grindcore of the short variety (both albums are 19 songs in just
above 2 minutes), but the ep (The Piece.....) is a simple acoustic
song in 5/4 with some weird stuff on top. Even managed to use zita-at1
in there. It'll only take you 7 minutes to listen to all the three
releases, so take a listen to the band that only exists because we
thought it was funny that noone had ever used this word in a bandname
before ;p

I recently discovered this very nice little application
http://www.good-ear.com/servlet/EarTrainer?chap=0&menu=0
It runs well with Firefox on Windows but I have not had any success in
getting any sound from its little built-in player.
I have tried fiddling with the QuickTime plugins, selecting various midi
add-ons, using mozplugger plugin, JACK on/off but no luck so far.
Does anyone have any ideas that I could try to make it play?
Tony
