Re: [LAU] Audio editor for editing a 90-minute-long file?

Using snd-ls, you can just mark the area you want in a new file, and right click, select copy to new or save selection.

Re: [LAU] How to move devices to specific IRQ's ?

by Susanne Schneider

hi, I'm facing similar crappy IRQ settings on my Thinkpad R61 here as Svend-Erik described - my cardbus shares it's interrupt with the graphicscard. I spent 2 nights now to play around with the (only available) settings in bios, which was to adjust pcibusses from preadjusted "11" to anything else and finally "automatic" - without any success. I tried to switch off APIC, ACPI, I tried pci=assign_busses - nothing changed. I wonder if it would make sense then to spend the money for a device like E-MU 1616 or even RME Multiface... Things seem to be a little better on firewire - the 1394 only shares it's interrupt with a unused usbbus and the also unused onbordsound - would it be probably the better way to go for a, lets say, Presonus Firepod? I'm sorry to further stress that exasperating hardware item but it's really a pain to find a solution - there is a huge amount of info out there in the web - but finding something which really leads one further can be a punishment. thanks a lot for any hints Susanne

Audio editor for editing a 90-minute-long file?

by Ken Restivo

Can someone recommend an audio editor for editing a 90-minute-long WAV file? I almost always use Rezound for songs (2-10 minutes long, ususallyl), which I like a lot, but it chokes on big huge files-- too slow, crashes, gets kicked out of the JACK graph, and generally sucks. -ken

Howto move devices to specific IRQ's ?

by Svend-Erik Kjær Madsen

Hi I'm into shapeing up my system to work better. I have installed a Debian lenny and migrated 64Studio multimedia packets on to it, and use 64studio's kernel 2.6.21-1-multimedia-486, then installed irqbalance and try to find the best setup for my RME Hammerfall Multiface card. I use a lenove T61 laptop and my problem is that the PCMCIA card share IRQ with some usb device on IRQ 16: debian:~$ cat /proc/interrupts CPU0 CPU1 16: 5328 20016 IO-APIC-fasteoi uhci_hcd:usb4, yenta,hdsp I want to move my hdsp to another IRQ, but can't figure out howto, it is a matter of firmware version on my Multiface card ? I can't move the PCMCIA card since there is only one available slot.... /Sv-e

Re: [LAU] Rosegarden/distro

Gey wrote: For me there are only two serious audio distributions: 64Studio (Debian based) 64bit and 32bit or Jacklab (OpenSuse) 32bit 64Studio is stable and has gnome and a nice packaging system, but is also (like debian) a bit conservative with nonfree Software. Jacklab is more about experiments but things like linux-vst and wineasio are part of the concept. Jacklab comes with KDE or E17. greetings, Nils on 64Studio You're bound to get some comments on a post like that! I agree that studio64 is probably the best. I don't use Suse on the getting in bed with the devil principle. But I also prefer Kde or Xfce to Gnome. The latest Musix is very impressive, though maybe not really cutting edge. dyne:bolic is very cool. However I make most music on my everyday Debian/kde testing, which is updated regularly. No RT kernel like Studio64 or Musix etc., but Jack still runs nice with about 6ms latency on the vanilla kernel. And no rebooting after browsing, mailing or killing evil zombies in a 3d game. :) Roger

We use a (expensive) program on windoze called Resolume at work for this, and I was just wondering if Linux could do it. A program called VeeJay was quite good, and also Gephex. Look for Linux VJ programs, I'm sure some can be MIDI controlled, and usually play video, add effects as well as stills. Sorry I cant narrow it down better (I'm a sound engineer, not a VJ), but you may not have considered this type of app yet and you could be lucky. Roger

If you are watching resources why don't you just install fluxbox and use that as your wm instead of a desktop environment like gnome. Fluxbox allows you to keybind it like crazy. It is light and fast. You can edit the menu really easily using some of the utilities that come with fluxbox or using vim. You can put whatever scripts you want or need in the menu. I am sure you can all of this stuff in any WM though. > > Firstly, do you guys think that a move away from Ubuntu Studio would > be beneficial? Not at all. A big waste of time. I started out on Debian. Then moved to Red Hat. I liked RH but ran into problems. It was not a big deal. I fixed them. I switched then to Gentoo. In Gentoo I spent LOTS of time being a Sysadmin. I was always wondering what is the right very of jack that I should be running for ultimate stability. Then I had to recompile stuff that was compiled against jack. That was also not the only problems I had. I then discovered Ubuntu. I have never used anything else since. That is except for a server I have that runs Debian. I love Debian and Debian based distros. Very easy. It is very simple create your own .debs if needed. In Gentoo I spent lots of time writing all these .ebuild files because I was not satisfied with the overlay's ebuilds. Anyway, I am using Ubuntu know. I actually use gnome for everything I do because it seems to perform fine. I have not had any troubles with it. My wife likes it and thinks its easy. She can update it and install things if she needs to. I tried Studio64. It was nice but did not see really any advantage over Ubuntu Studio.

I've not noticed this before but it interested me. I've done some experimenting, only to find that the controller channels don't work properly. I've filed a bug report with the GIMP ( http://bugzilla.gnome.org/show_bug.cgi?id=537960 ) and a patch which has been accepted so if you do want to try it, you might want to have quick look at the bug report to see what might happen.

Re: [LAU] Boss GT-10

by Pedro Ferreira

OK, I managed to make the audio work with ALSA, but, for MIDI, a specific driver is used and, guess what? only Windows and OSX versions are provided... well, at least i have audio, but patch programming would be much easier with usb-midi working :(.

applying reverb to sample

by Atte André Jensen

Hi I have a couple of samples I'd like to statically apply reverb to. I tried both mhwaveedit and audacity, but can't figure out how. Esp since the sample is gonna be longer with the applied reverb. What's the easiest way to achieve this? -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk
