Greetings: SF announcement seen on the AGNULA list: "OpenMusic V (for Linux) will soon be available here in cvs. We will have to completely rearrange the structure of all files found here. The 4.7 version is completely obsolete. since OpenMusic has been cleaned up and uses now SBCL lisp compiler and Clg-gtk+ bindings for the Linux version. You will soon have fresh news here. " http://sourceforge.net/forum/forum.php?forum_id=613354 I worked with the older version for Linux, it had promise but was unfinished compared to the great version for the Mac. Maybe this time we get it all ? Best, dp

[linux-audio-user] [ANN] QLoud v.0.17 - harmonics (distortions) plotting is added

by Andrew Gaydenko

QLoud is a tool to measure loudspeaker frequency response and (yes!) distortions. Find it here: http://gaydenko.com/qloud/ Changes: - harmonics (distortions) plotting is added, - as a result, noticeable part of common code was refactored/rewritten. Direct screenshot link to harmonics plot: http://gaydenko.com/qloud/screenshots/shot03.png If you have a sound card with good DAC and ADC, you can plot harmonic distortions for another audio equipment, say, for your power amplifier - cited screenshot has also harmonics plot for loopbacked sound card.

[linux-audio-user] Do I need a preamp for the SoundBlaster Live?

by Tim Beauregard

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, The spare room in our house is used for both singing lessons and computer activities. We are embarking on an audio adventure, with singing students holding a Shure SM58 microphone which is plugged into the jack on the front of the PC (a SoundBlaster Live! 5.1), singing to backing tracks played through the PC speakers/headphones. This is for them to practice using a microphone. My question is basic, do I need a preamp for the microphone or is the LiveDrive doing that job? At the moment the volume which is high enough to hear through the speakers is very close to feedback volume, and also sounds distorted. Thanks!

[linux-audio-user] Intel HDA and Jack

by Sampo Savolainen

Hi, I have a brand new Dell D820 here which has worked very well, except for jackd. But: I just found a way to get jackd running! (Thanks Paul) Use the -S switch for jackd's alsa driver to force the sound card to use 16 bits instead of 32 bits. For example: jackd -R -P80 -dalsa -dhw:0 -r48000 -p256 -n2 -S The "fix" is way far from optimal because of all the lost percision, but as I'm going to use my multiface anyway (as soon as I get the interface card) for serious work, I don't care.

[linux-audio-user] Command line tool for sending SysEx to a syhtn?

by Ismael Valladolid Torres

I've seen SysExxer and it looks very nice. Unfortunately it's not packaged for Debian and as I'm a Gnome user I feel a bit boring installing KDE libs for compiling. Is there any straightforward command line tool for sending SysEx to my synth? If the answer is *no* then I'll go for SysExxer.

I am running mine with a realtime-lsm enabled kernel. Any member of the "audio" group should be able to use jack. Jack starts fine. Bristol cannot interface it. Do I need suid? If so, where and how do I set it (engine?)

[linux-audio-user] Where to do a computer music related PhD

by Loki Davison

I'm currently searching for somewhere to do a computer music related PhD (Doctorate) and i'm wondering if anyone on LAU has any ideas or useful contacts. I have a few different ideas for a topic and i'm open to working on an already existing topic as well as my own. I'm especially interested in human computer interaction in computer music. I just got a letter back from the aussie uni I applied for saying they arn't taking any new PhD students for 2007... so on the search again. :) Loki

[linux-audio-user] dssi-vst help required

by Michael Stein

I have had good success running dssi-vst (vsthost)and fst under kubuntu, however the Native instruments Plugins seem to fail continually. I have tried simply point both of these apps at the NI plugin.dll files, but to not avail. Does anyone have experience or a how-to on how to get these plugins working? Any help is very much appreciated.
