Hi, My first steps with lilypond : I cannot find the file "drums.scm", I thought it could be in /usr/share/lilypond/2.2.0/scm/ but itsn't. What should I do ? Thanks, PL

[linux-audio-user] Is there a way to compress the size of a wave file?

by Flash Love

I recorded a one hour audio session using windows Sound Recorder for a friend and much to my chagrin and my friend's dismay, the Audacity edited file is over 400M! This friend is now telling me that in the past when the same one hour recording session was done the file size never exceeded 27M. I do not doubt them, but I have no idea how to reduce/compress this wave file. If someone knows how I can reduce this one hour wave formatted session to a file size of 27M, please let me know. Thanks Flash

[linux-audio-user] 2.6 which patches

by Noah Roberts

I am compiling 2.6.11 and having trouble finding the patches I am supposed to use for low latency. In scouring the internet I find old references to a Realtime LSM, a Low Latency patch, and the Pre-emptable kernel patch. The later is included in the kernel now and I turned it on. The low-latency patch seems to only be findable as a patch to 2.4. The newest LSM is from a year ago. The user list website has a how to but it seems rather dated: http://www.djcj.org/LAU/guide/Low_latency-Mini-HOWTO.php3 Last update 2 years ago. What are the current set of patches you use and where are they? More importantly, how to you ready a CURRENT kernel for use with audio and where is the HOWTO on that? Thanks.

[linux-audio-user] Muse Research's RECEPTOR ?

by NiXO Beee

Hi, I know the matter might be subject to flame (because this piece of gear is not intended to run free GPL software), but it is running GNU/Linux (a modified Redhat, with a Wine environment for running VSTs and VSTis, I think), so I guess it might be somehow in relation with the list... Well, here are my questions. Are there any RECEPTOR users in here ? What is this machine really worth ? Is it expandable with Linux free audio software ? (I guess no, but why not ?) May it be usable for multitracking audio, or is it just a plain plugin player ? Is it really stable ? Doesn't the Wine environment create an awful overhead, given the specs of the machine ? Thanx in advance for your lights :) And sorry if it's been discussed before, don't flame me and just point me to the right archive... PS : for those who never heard about this Receptor, here is the URL : http://museresearch.com/receptor_overview.php -- [ NiX=O Beee ] -- Quand un philosophe répond, on ne comprend plus la question qu'on lui avait posé.

[linux-audio-user] Modular controller

by Juhana Sadeharju

Hello. This is an interesting controller product: http://mawzer.com User may build a custom control surface with simple controller units. It is quite interesting because I invented the modular controller concept 10 years ago. The Mawzer design is quite similar to my design.

[linux-audio-user] Loading Soundfonts in an audio card

by Lisandro Damián Nicanor Pérez Meyer

Someone has asked me if it is possible to load soundfonts in a (I think) Soundblaster. The point is that he can do it in window$, and doesn want to spend cpu cycles doing in "the soft way". If I'm not clear enough, please tell me. Regards, Damian- Women should be obscene and not heard. -- Groucho Marx

Re: [linux-audio-user] Re: realtime lsm module and kernel

by Brian Redfern

I'm using demudi version 1.2.1, the version of Muse is the one that comes with that demudi release, I get an error that it can't get a lock on RTC, maybe I just need to change permissions somewhere. __________________________________ Do you Yahoo!?

[linux-audio-user] realtime lsm module and kernel 2.6.11 on Debian

by vescovi christophe

Hi all, I recently switch from mandrake to debian and I have some problems when trying to upgrade the kernel. I have installed the kernel-image-2.6.11, kernel-sources-2.6.11, kernel-headers-2.6.11-1. Since no Debian packages exist for realtime-lsm-module for 2.6.11 kernel, I decide to build from sources. I have link /usr/src/kernel-headers-2.6.11-1 to /usr/src/linux, compile realtime-lsm, install it all seems ok. The only problem was that realtime.ko was in /lib/modules/2.6.11/extra/realtime.ko. As indicated in the realtime-lsm README I try to do "make modules_install" in /usr/src/linux but it does not seems to do anything so I manually "cp /lib/modules/2.6.11/extra/realtime.ko /lib/modules/2.6.11-1-k7/kernel/security/realtime.ko". After that I could modprobe realtime any=1 mlock=0 allcaps=1 without error but starting jack with realtime privilege always return me this error : > jackd -R -dalsa -S jackd 0.99.0 Copyright 2001-2003 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details loading driver .. creating alsa driver ... hw:0|hw:0|1024|2|48000|0|0|nomon|swmeter|-|16bit control device hw:0 configuring for 48000Hz, period = 1024 frames, buffer = 2 periods jack_create_thread: error 1 setting scheduler parameters after thread creation: Operation not permitted cannot start watchdog thread cannot load driver module alsa Any ideas ?

[linux-audio-user] [ANN] Linux Musicians Wiki

by James Stone

I don't know if everyone is getting bored of Wikis, but I have just set up another one(!) This time to provide a central site for Linux Musicians to provide links to their music, and to give information about how it was produced. I think this would be really interesting (at least I would find it very interesting so I am sure that others would too), and judging by the excellent music that has been posted to this list, there should not be a shortage of content (I hope). So far, I have just put some of my music up there.. I am afraid it really isn't that brilliant (I am working on some new stuff at the moment).. but I thought I had better show willing! The way it works, is you have to host the music on another site and provide a link to it. Open source audio collection is a good option if your music falls into that category, and you cannot host it anywhere else: http://www.archive.org/audio/collection.php?collection=opensource_audio Anyway, the Wiki is up at http://linux.wikicities.com/wiki/Linux_Musicians I hope people will find it useful.
