[linux-audio-user] sfArk on Linux ppc

by Ismael Valladolid Torres

Any way to uncompress sfArk compressed soundfonts on Linux ppc which doesn't involve running Windows or a x86 Linux as a qemu guest? Cordially, Ismael -- Dropping science like when Galileo dropped his orange http://lamediahostia.blogspot.com/ http://www.flickr.com/photos/ivalladt/

[linux-audio-user] Jack + kernel problem (client_thread zombified)

by Julien Claassen

Hi! I have a small jack problem with kernels 2.6.13/2.6.15 (it works with 2.6.11.8 alright). I compiled first the kernel and then jack 0.100.9 (also tried earlier 0.100.1). When I start jack everythings ok, but then after a while, mplayer will stop and say: Jack: client_thread zombified. Can anyone imagine what this is all about? Oh yes one last note: I used the mm-patches for 2.6.13 and the exact kernel version of the other kernel was 2.6.15.2 (I only mention this, because I first tried to patch the kernel, and it told me that a few files semmed already patched. So I did it without mm). Can anyone help me, suggest a solution, something to test, to clarify this matter?

But it has to be set up, and many/most of us would never use an icon or a menu to start most programs. > If you use a terminal > to start them, just define an alias. No no no.

If the nature of the program is that some threads need to run realtime, those threads shall also run realtime by default. What you are proposing is the complete opposite.

[linux-audio-user] Kernel 2.6.15.3-rt tests

by Marcos Guglielmetti

Hi, I am working with this kernel right now. I compiled it into my GNU Linux box (Musix 0.30) following: http://ubuntustudio.com/wiki/index.php/Breezy:Vanilla_Kernel_With_Realtime_… And it works fine, but with a few "bugs" or problems. You can download it from: http://www.k-maleon.com/musix/deb Tests: PC Duron 1800Mhz, 120Mb RAM, HD 7200 RPM, SB Live! sáb feb 11 18:34:03 CET 2006 Kernel: Musix GNU/Linux, kernel 2.6.15.3-rt-musix-2006-11-02 *rtirq works normally *Normal users can use RT *With: /usr/bin/jackd -R -P89 -t1000 -m -dalsa -dhw:0 -r44100 -p512 -n2 -s -S -i1 * Good: Ardour with 7 tracks and a lot of LADSPA FX: it worked well enough, using jackd in duplex and play only mode (with a 512 buffer, 44100Hz) * BAD: into this session, I opened JAMIN and all the system went very slow. Then I restarted jack into play only mode and it worked well: I could master the tracks connected to Jamin from Ardour outputs. lesser buffer size: * Regular: JAMIN, jackd duplex, buffer 256, it works fine, but whe i opened ardour: 4 (28) xruns while the hard disk was reading/writing. I think that with more ram than my little 120Mb it can do it much better. * Fine: jack: 48000 Hz, 1024 or 128 buffer (46ms latency or 5ms latency), play only mode, Ardour with 7 tracks: NO XRUNs at all. I opened Jamin and all goes well with 1024 buffer, but with the 128 buffer the system just got paralyzed. Hope it can help or serve you. Musix uses the DeMuDi kernel (when installed on HD). I'm needing to make a RT kernel that could boot from the Live-CD out of the box, so I am experimenting with it. I could not compile unionfs, but I will try again in these days.

I don't find that amazing at all. The terratec dmx6 fire is a very descent card. Are you sure you're not thinking about a different card?

[linux-audio-user] fastbreeder (a genetic programming synth)

by Dave Griffiths

An experimental genetic programming synthesiser. This program is free software, developed for linux, using jack for audio. Fastbreeder is essentially a 4 button synth. The idea is to grow code by choosing from a range of automatically generated variations of functions, you don't have to know how they work, but each function creates a sound which can be selected by you. The following generation is then created containing mutants of your chosen sound. You can refine and develop the sound just by auditioning and choosing the best one each time. http://www.pawfal.org/Software/fastbreeder/ For those in the London UK area, I'm doing a short show and tell of this app at the next dorkbot: http://dorkbot.org/dorkbotlondon/ cheers, dave

[linux-audio-user] Re: Acid type program

by Juhana Sadeharju

>From: Victor Lazzarini <Victor.Lazzarini(a)nuim.ie> > >I'd add Csound to that list... I used Csound as a replacement to Acid type arranger at 1997. I wrote C code library for placing sounds and loops to the beat bars and to the tracks. My program then wrote the timed events to Csound score. The textual arrangement was not the problem, but every change to arrangement required a compilation of my C code. I would be interested in to know if Csound can be used as an audio engine in Acid type software. Then one would need only write a GUI. Or a textual UI as in trackers. Can the orc and sco data inside Csound be incrementally build and modified via liblo? A poor alternative would be that the entire score would be sent each time.

[linux-audio-user] hardware requirements for audio

by emanuele ..:: www.rumoridifondo.com ::..

when i play hexter from rosegarden and with 32note of poliphony i get some xrun with jack. the same if i play "The Master" synth in LMMS. now i got a doubt: what are the raccomended requirements to make audio with linux? i got a celeron 1.7ghz and 512 mb ram and i'm using ext3 filesystem. with this configuration and windows xp and cubase sx2 i manage to record & play with B4 fm7 absynth battery hyper canvas, all open at the same time and i don't have problems. is it possible that with linux and rosegarden and hexter i got xrun problems? may they depend from system configuration? i use mandriva's kernel multimedia with realtime module.... bye emanuele
