[linux-audio-user] HyperMammut - I released a new software for processing sounds and images

by Paul

Hi. I released today an experimental software that allows you to process the sound/image as a single FFT (and other) transforms. Also, the program can transform sound to images and vice-versa. Because of this, you can apply a blurring or swirling effect to sound, or revereberation/flange effect to images ;-) Many effects sounds/looks very strange (in my opinion theese are the strangest sounds I ever heard - hard to describe in words - better listen them). You can download the alpha-stage source code from http://sourceforge.net/projects/hypermammut and I recomand you to see/listen some examples at http://hypermammut.sourceforge.net A related software to this is Mammut ( http://www.notam02.no/notam02/prod-prg-mammuthelp.html ), but this programs aims to be modular and to do more :) Paul. __________________________________________________ Do You Yahoo!?

[linux-audio-user] Re: LKML: Time to remove LSM

by vlad

hi all, i don't get it! in which ubuntu package (dapper or breezy) are the rtlimits-pam-modules? they are not in the libpam-modules package. i'm using ubuntu breezy with a self-compiled kernel (2.6.14-ck9) with realtime-lsm. BTW, why is the realtime-lsm method deprecated? i think it is safe. PAM is quite delicate (that's why i don't want to build it myself). vlad

[linux-audio-user] LKML: Time to remove LSM (was Re: [RESEND][RFC][PATCH 2/7] implementation of LSM hooks)

by Mark Knecht

Hi, This thread is happening on the Linux Kernel Mailing List. Since I'm not a programmer I don't understand the full ramifications. Can someone here tell me would this render the realtime-lsm module unusable and if so what would I have to do to get realtime operation without realtime-lsm? Thanks, Mark

[linux-audio-user] (i have problems with my Network link) Need testers for the performance of 24ch netjack connections

by torbenh＠gmx.de

hi... roger i am CCing you because a) i think the problems are via-rhines fault in 2.6.16 b) this software reproducibly triggers something have not seen before i need people who test the new fragmentation code in netjack-0.12. i think i am seeing kernel problems, because there are patches going on for the via-rhine driver. it looks like the huge packet load triggers some sort of bug in the via-rhine network driver. Because after using netjack for some seconds, the link is broken. (this is reproducible with 2.6.16) "ifconfig eth0 down; ifconfig eth0 up" fixes it again. i dont think that the results i am getting are reliable. So i am asking you to test it. please check out http://netjack.sf.net/netjack-0.12test1.tar.bz2 compile as usual with: bash# scons jack_source_dir=<jack_source> then on the master with normal jackd running: bash# jacknet_client -p <other_machine> -P 24 -C 24 on the <other_machine> bash# jackd -R -d net -C 24 -P 24 please note that -r and -p on jackd -d net are no more needed and autodetected. i would also be interested in OSX results of the old netjack-0.11 for OSX compilation add "with-alsa=0" -- torben Hohn http://galan.sourceforge.net -- The graphical Audio language

OK, last night I did a test install of FC5 as an upgrade to my FC3+planet installation. If I log in as root, Jack is in realtime mode, and can't overload my system enough to cause even one xrun. But when I am logged in as a normal user, Jack doesn't run in realtime mode, and I get xruns even on playback. Is this caused by something PAM related? (Forgive me, I am a relative newbie)

[linux-audio-user] Doing Drums

by BJaY

I trying to figure out a method of doing contemporary drums, where I can edit in a matrix like environment but then get separate Jack outputs for each drum to allow for DSP'ing. I currently use Rosegarden synced to Ardour. Rosegarden will not allow splitting notes to different channels - though Muse does, but that means I have to run both (I don't know if they'll play happy together). I revisited hydrogen again recently, but it won't load gig or sf2, as far as I can see (Has some nice kits though). I like the idea of using Linuxsampler to do drums but I can't see a way of directing one drum to one engine / output and another to another. I feel like there is a simple solution here that I'm missing, it must be a very common requirement in digital audio. Anyone got any suggestions ? Cheers, Bruce.

RE: [linux-audio-user] Doing Drums

by BJaY

I've found a solution : Qsynth with loads of outputs with QMidiRoute re-arranging the notes onto different channels. As far as Hydrogen is concerned, it's great but the impression I get is that most of the sample sets around are sf2/gig. How about a conversion utility, sounds like somthing straight forward. Thanks for the suggestions, Bruce.

[linux-audio-user] getting my priorities straight

by Atte André Jensen

Hi Sorry for cross posting, but I figured the solution to my problem could be with both csound and my linux/kernel setup, so here goes: When running csound5 under X I get "WARNING: Buffer underrun in real-time audio output" from csound accompanied by a click, whenever I "do something", including tab'ing from xterm to xterm. Looking at top I figure a solution would be to have csound run with lower nice value or higher priority. Is that a viable solution? If so, where do I change these settings and which should I change and to what? I have this in my .csoundrc: -+rtaudio=alsa -o devaudio:hw:1 --sched --expression-opt -b 64 -B 256 -d -m 7 -M 0 I have a patched 2.6.15.6-rt21 kernel and run debian/stable on a pentium 4, 2.4GHz laptop with a edirol UA1A usb soundcard. I didn't "do anything" with my IRQ's since I don't know how to or if it's nessecary...
