Is it really necessary? Can we say the same thing in a nicer manner? Maybe a hundred posts one after another: That must suck, et al. I think folks of our intelligence and talent can do better.

[LAU] optimizing jackd build

by Dragan Noveski

hi list, i read some threads in the ardour forum about optimizing the jackd build, so i would like to find out, if i can build jackd here with more optimizing ...since i think that more optimizing is better than less optimizing?? the way i am building jack until now is simply: ./configure --with-default-tmpdir=/dev/shm/ when i run configure like this, i turns: jack-audio-connection-kit 0.103.0 : | Build with ALSA support............................... : true | Build with FreeBob support............................ : false | Build with OSS support................................ : true | Build with CoreAudio support.......................... : false | Build with PortAudio support.......................... : true | Compiler optimization flags........................... : -DREENTRANT -O3 -fomit-frame-pointer -ffast-math -funroll-loops -march=i686 -mmmx -msse -mfpmath=sse | Compiler full flags................................... : -I$(top_srcdir)/config -I$(top_srcdir) -I$(top_srcdir) -D_REENTRANT -D_POSIX_PTHREAD_SEMANTICS -Wall -g -g -O2 -I/usr/include/nptl | Install dir for libjack + backends.................... : ${exec_prefix}/lib/jack | | Default driver backend................................ : "alsa" | Shared memory interface............................... : "System V" | Install prefix........................................ : /usr/local the processor type in the kernel config here is 'Pentium M' but i don't know if the '-march=i686' could be changed with something like 'pentium M'. since i am using a self made kernel, only a little help in this issue would help me a lot. cheers, doc

[LAU] ADAT blackface and RME DIGI 32/8

by Johan

Hi, I am trying to get some older equipment to work with Linux. Specifically an ADAT blackface and a RME DIGI 32/8 card. Is this possible? My problem is that the red error led on my card does not stop glowing when I attach the digital out from my ADAT to the digital in on the soundcard. Drivers appears to be recognised and I can chose between different input methods in GNOMES mixer applet. I have heard that I need to send some audio from the computer before the ADAT sends a valid clock signal, but how can I do that when the card refuses to work without a valid input signal? Thanks Johan

[LAU] speech recognition?

by Loki Davison

Anyone know of any working linux software for speech recognition? Being able to use shortcuts etc with it would be great. I.e to control web browsing. I can't seem to find anything except for ancient references to viavoice. I'm trying to cut down on typing to hopefully speed my recovery from RSI / overuse injury. If anyone has any hints for that i'd love to here too! Loki

[LAU] That must suck. For me it's about beauty -- music is just one path

Maybe noise is beauty... I dont know... the sounds of the ocean are like noice, just like the wind too... I think this is beautiful, but, because I dont like the car's, bus, planes, trains, etc., sounds, I think there is almost no beauty into the industrial age sounds (factories, etc.) So... when I try to make what I call music, I try to put some beauty on it... maybe a wind sound could be nice for some parts, but I will try to include melodies because the occidental's traditional concepts are into my life, my feelings. it's a long subject... -- Marcos Guglielmetti * Director del desarrollo de Musix GNU+Linux, 100% Software Libre * CD Download: (http://www.musix.org.ar/en/) * Colabora: http://www.musix.org.ar/wiki/index.php/Musix099_tasks * Videos, programas y otras cosas en: ftp://musix.ourproject.org/pub/musix/ * Reporte de errores a: https://www.musix.org.ar/wiki/index.php?title=Problemas-Bugs *IRC: #musix channel on freenode * http://autosus.wordpress.com/ «No te tomes en serio nada que no te haga reír» [un amigo de E.

[LAU] latency issue

by julien bodd

Hi all, I have tons of xruns and sound saturation in some specific case. I use freewheeling + zynaddsubfx. The connexions in qjackctl are specific : - my external midi keyboard is connected to freewheeling midi in. - freewheeling midi out connected to zynaddsubfx midi in. - zynaddsubfx audio out connected to freewheeling audio in - freewheeling audio out connected to alsa_pcm The reason for this strange connexion is because I use my midi keyboard to perform some freewheeling actions, but freewheeling has to pass the non-relevant midi event it gets to zyn (the notes I play). It is this kind of loop (freewheeling, to zyn, back to freewheeling) that cause the xruns !! I mean that if I connect my midi keyboard directly to zynaddsubfx and zynaddsubfx audio out to freewheeling audio in, then it is ok !! But, I really need to control freewheeling too from the midi keyboard. BTW, the problem does not appear with the first connexions I described, if instead of playing from the midi-keyboard, I play from zynaddsubfx integrated visual keyboard. Anyone experiencing the same problem? Any idea? Thank you very much !

Re: [LAU] Foul Language

by Chuckk Hubbard

I was born in '75. No one my age in school even knew his name. He was born in '46, that's not exactly my generation. Whatever generation he was, I just happen to think he was the most brilliant musician in the 20th Century. I don't mean the noise or the vulgarity or the humor, I just think he composed the most beautiful melodies and harmonies, in between all the attention-getting. -Chuckk On 4/8/07, David Stephens <linuxrootuser(a)gmail.com> wrote: > Your father's generation?

[LAU] [ANN] One time chance to order your own LAC'07 t-shirt!

by nescivi

Hi all, After a while of recovering and figuring out the details on how to do this, we have now set up a little form online for you to order LAC'07 t-shirts. The t-shirts will have the same quality as the t-shirts you have seen the organisers wear, throughout the LAC in Berlin. This is a one-time offer only, and be sure to put in your orders soon, as the offer will only stand up until the 16th of April. We want to have the payment in advance, as we need to pay the cost of printing, packaging and postage. Please use the link on: http://www.lac.tu-berlin.de to go to the form, get more detailed information and order your shirts! sincerely, Marije
