You can't escape all of >the Mandrake rpms on the net though... I doubt you'd have a problem. > > > Is it even possible to download a Mandrake RPM? Every time I try to download an audio package from a Mandrake repository it complains that I don't have the necessary dependency packages installed on my internet machine, and asks me to insert one of more of the Mandrake 9.2 discs into my cdrom drive. After installing packages I don't really want on my internet machine, I click on the download link and it *INSTALLS* the package I want to put on my audio machine at home on my internet machine. YUCK. Is there any way to download these packages so I can burn them to a CD and bring them home to my audio machine? Or maybe repackage them from the installed copy? My audio machine at home is not on the internet, and never will be due to the presence of unreleased audio tracks - no network connection is the most reliable firewall ever created. Evey time I move a desktop machine I always have trouble getting it back up and running again. I have quite a few friends who do this regularly, but they have custom built machines in shock mounted cases (as my next one will be; my current machines are rebuilt slavage in commercial cases). e. j. branagan The MUSE - Nashville, TN

Most room resonences are corner to corner (in a box-like room). Sound behaves a lot like light in a three-way right angle corner - It comes back out the same direction it went in, just like those three way mirrors they use to reflect laser beams back from the moon. Most studios these days try to avoid any right-angle corners. e. j. branagan The MUSE - Nashville, TN

[linux-audio-user] minimum requirement for a real-time FX processing machine

by caffeine

Hi everybody, first of all thanks for your answers to my previous posts. Now that I'm having fun playing around with a bass guitar and ecasound, I'm thinking about buying an old laptop to use during rehersals and maybe gigs. I'm wondering what kind of hardware would do the trick. I'm kind of broke so the older (i.e. cheaper) the better (it would just run a shell, a tweaked kernel, JACK and FX processing stuff). I guess I may run into problems with obsolete sound cards (an area I'm not much knowledgeable in) and probably other issues I don't know about yet... Anybody has any experience/knowledge to share ? What would be the absolute minimum requirement for you ? btw, I'm also wondering about vibrations damaging the hardware, particularly the HD (the box would sit on top of a bass amp, or at least not so far from it) What do you think about it ? Thanks for taking the time to read this.

[linux-audio-user] Re: Live Recording headphones

by ejbjr

OK, we've had a lot of good discussion about good studio headphones. How about good headphones for live multitrack recording in a very loud room. Good isolation and relatively high volume. e. j. branagan The MUSE - Nashville, TN

Have no use for it, and it is very annoying. I do a more general approach; turn off all cron-jobs if anyone is logged in. After installation, this script is run: " if grep "run-parts " >/dev/null /etc/crontab ; then cp -f /etc/crontab /etc/crontab.org sed s/run-parts\ /run-parts2\ / </etc/crontab.org >/etc/crontab echo "crontab changed" fi if grep "run-parts " >/dev/null /etc/anacrontab ; then cp -f /etc/anacrontab /etc/anacrontab.org sed s/run-parts\ /run-parts2\ / </etc/anacrontab.org >/etc/anacrontab echo "anacrontab changed" fi " and /usr/bin/run-parts2 looks like this: " #!/bin/bash if ! ps -A |grep ssh-agent ; then run-parts $@ fi " At least this works for fedora core 1. Don't know about other distributions. --

[linux-audio-user] APIC is bad?

by Florin Andrei

I rebuilt the latest Fedora 2 kernel update to enable preempt and IO-APIC. I'm not yet sure about preempt, but IO-APIC has been acting weird. It gave me more interrupts (up to 21 instead of 15), but the devices were distributed suboptimal. Without APIC, the nvidia module was alone on its own interrupt, the EMU10K1 was alone, the ide and eth modules were on separate interrupts, etc. Quite ok. With IO-APIC, nvidia, EMU10K1 and bttv were on the same interrupt, ide2, ide3 and eth0 were on the same interrupt. Instead of messing with the kernel again, i just rebooted with the "noapic" parameter and now the interrupts are looking good again. BTW, anyone has any measurements on how bad it is to put essential devices on the same interrupt? (in terms of xruns) -- Florin Andrei http://florin.myip.org/

I'd say my beyer dynamic dt100's are still the best thing since sliced bread. Great for getting through insomnia driven editing sessions.
