scheduled server downtime - 10/Jan/12 - linuxaudio.org

by Robin Gareus

Hi all, As you may or may not have noticed, linuxaudio.org was rebooted today 15:06 UTC. The server now features shiny (faster) new virtual HDDs (with backups and everything..). Sponsored by the Virginia Tech Department of Music and DISIS. Cheer a loud "Hip Hip,..." to Ico, who made it possible in the first place and send Kudos to Brian Maloney from the vt.edu tech dept for outstanding excellent GNU/Linux support! All systems go. robin

Fwd: sndfile-waveform PNG generator ?

To: Robin Gareus <robin(a)gareus.org> It's fairly trivial to write one your own with python using scipy. Should be in the ballpark of 20 lines or so.

sndfile-waveform PNG generator ?

by Robin Gareus

Hi *, Is there a command-line tool akin to `sndfile-spectrogram` that generates an image (preferably PNG) of an audio wave-form? I found endless GUI apps, but command-line tools are scarce. TIA robin

New Avantgarde Music - or just more Prog?

by Julien Claassen

Hello everyone! I've just completed my latest piece and it has reached its intended audience, so I'm ready to post it here. It's called Raw Magic: http://juliencoder.de/nama/raw_magic.ogg http://juliencoder.de/nama/raw_magic.mp3 And you can find lyrics here: http://juliencoder.de/nama/raw_magic.html Or of course visit the music page at: http://juliencoder.de/nama/music.html This time I'd like to utter my heartfelt thanks to Joy Bausch, for guitars. A nice job! I'd like to thank S. Massy, Gabbe Nord and the mysterious Mr. Bennett for being my second pair (and third and fourth :-) - though not necessarily in that order) of ears. Without you I'd still suffer from some of my mixing difficulties. And I'd like to thank Silvia. The beginning of that song the first four notes or so came to me in a small bar in Paris almost two months ago now. I thought of some more notes there, but they didn't sound right. :-) The other main idea followed later that day, after having attended a concert by Goran Bregovic. So this piece again stretches the boundaries of my usual influences. You'll find some light asian influence, the balkaniser, simple piano music, light jazz, metal, glam-rock, synth-pop and a bit of the good old prog all bundled into this. And it's not because I didn't know, whereelse to put them. It's actually a study of some rather personal experiences, seeing them from very different angles. I hope I succeeded. :-) I know, that my singing leaves somethig to be desired (better intonation for a start :-) ), but I suspect, that it could have been worse. As ever any feedback is welcome and a beer to those, who find the fun and games in the lyrics. :-) Kindest regards Julien =-=-=-=-=-=-=-=-=-=-=-=- Such Is Life: Very Intensely Adorable; Free And Jubilating Amazement Revels, Dancing On - FLOWERS! ====== Find my music at ====== http://juliencoder.de/nama/music.html .....................................

Please test the combo in your system. Any other midi sequencer? Rosegarden failed to install in Ubuntu (as well as GTK2 and SDL dev packages grrrr!). Juhana

Re: [LAU] OS for realtime operation

by harryhaaren＠gmail.com

Hi Moshe, Yup recent convert to Arch here, its a very nice way of keeping on top of your linux distro: All options are available to you, config files are *very* well laid out, and documentation is extremely good. For configuration its really flexible, but it does require a certain amount of config before its running optimally in my experience. That said, configuring it is very easy and rewarding, it just does what you tell it to do, without trying to be smarter than you and changing stuff for you. AVLinux is a more "polished" solution and you'll no doubt need less effort to get it running, but then you've lost some control over how it works, and you'll have to pray its good. TangoStudio is Ubuntu based, and I had a pretty good experience there... not very RT performance, but stable @ 20ms or so. Here on Arch I'm pushing to 5ms, and getting pretty good results :) I'ma happy Arch user, but its definatly not the distro for everyone... as some Arch people put it: Arch doesn't find you, Archers find Arch -Harry On , Moshe Werner <moshwe(a)gmail.com> wrote: > Hi Raffaele, > thanks for the reply! > My needs would be: > Mainly tracking (by now up to 8 channels at given time). > Mixing and monitoring - Yep > Realtime fx - also yes. > Tried AVlinux and found it to be pretty cool, but its 32 bit and till now > I'm used to 64 bit and wouldlike to keep using the more advanced PC > technology.

How to get 64-bit Flash plugin to play through JACK2?

by david

I'm sure I have this somewhere in my mail archive, but search can't find it now ... Have heard of something called the alsa-jack-plugin, but can't find it anywhere. Have tried something else using something in .asoundrc (don't remember what it was, it didn't work, so I got rid of the .asoundrc I had created to try it - didn't have an .asoundrc file before). My lovely wife would like to watch her Amazon movies on my 64-bit desktop PC because it has the large LED monitor. Stupid computers. -- David gnome(a)hawaii.rr.com authenticity, honesty, community
