Looking for Portable Digital Recorder, on a budget

by The Other

There may have been a thread on this topic a month or so back, but I'm not sure what to look for. It's too noisy in my apartment for any audio recording. I first thought about portable DAT recorders, but my googling leads me to believe that's old technology. In American Musical Supply (AMS), I see the Zoom H2 digital recorder. I'll probably go to my church sanctuary for the vocal recording. The church's mixer has RCA L/R outputs I can tie into. Or I could use any mics included with the digital recorder. My computer has USB ports and is running openSUSE 10.2 with ALSA mixer 1.0.14, and have the Audigy2 ZS internal card. I can take a any type of output from the recorder (1/8" stereo plug, RCA L/R, XLR, and possibly digital out-- I haven't tried that with the Audigy 2 ZS) and get it routed to the ALSA mixer for use with Audacity or some other recording software. I'd like to stay under 100USD. The Zoom H2 is listed at 199USD. Suggestions? Thank you, Stephen.

Hello I like dssi-vst very much and play around with it the last day's. Now I wrote a little gtkdialog script, to select and load my plugins from a small GUI to dssi-vst. If someone want to check it out, it's here: http://brummer.de.hm/scripte/vstload.tar.bz2 hermann

usb soundcard: xruns and latency even with -rt kernel

by Jacob Lee

I'm using an M-Audio Transit usb soundcard with the kernel 2.6.22-rt, as packaged by ubuntu. I'm running jack right now with -p 3 -n 512, and I still get xruns, typically of values less than .03ms, every few minutes. Increasing the jack latency reduces the rate of xruns, but I can't eliminate them without using settings large enough to cause noticeable delay. I've raised the priority of the IRQ-16 process (the one controlling the usb bus with the sound card); I also tried to use setpci to tweak pci latencies, but for some reason the settings wouldn't apply (when I read the values back, they haven't changed). I've posted the results of rt-setup-report.sh (plus lsusb) at http://artdent.homelinux.net/~jacob/rt-setup-report . Is there anything else I can try? Thanks, -- Jacob Lee artdent(a)gmail.com

linux audio ready in 5 minutes - using which distro and interface?

by hollunder＠gmx.at

Hi there, I just thought that it would be nice to be able to record anywhere without having a computer with you. One would just need a live-CD and an audio interface and would be able to use almost any computer. I wonder which interface and distro would be best for the job. I think usb would be the way to go for maximum compatibility and I have no idea about the distro... I even don't know if it should use jack or not, since I heard that it doesn't work so well with live CDs. Any ideas? Best regards Philipp Überbacher

Studio reverb (impulse)

by Julien Claassen

Hi everyone! I need some reverb (impulse response) from a studio with a drumkit, so the vibrating snare and reverbarting toms are in there. Can anyone generate such a thing or has anyone a suggestion how to fake it in a satisfactory way? I could use csound to produce the fake. I don't have a real studio, nor a real drumkit, nor can I use one of Fons' nice new tools that do impulse response generation, because of their graphical nature. I'm glad and eager for any nice hint!

I must have looked at about 10 lists of LADSPA plugins by now, so you would save me much eyestrain by being more specific ;-) Ingen looks like it might be a decent host for what I want - I have to finish convincing Gentoo to install it. bye John

Huh? Here, if I start it like this: "timidity -ig -Oj some.mid" I can see audio ports in qjackctl; if I start it in server mode (using -iA and no filename) I see ALSA sequencer ports too. I think a good place to make it start automatically would be the "Execute script after Startup" in qjackctl's Setup dialog (Options tab). Edgar

Small, cheap computer speakers?

by Ken Restivo

I'm looking for a source for small, cheap, but relatively nice-sounding computer speakers, preferably ones that are powered off of a 12v wall-wart, for use in a mobile "studio". Many years ago, a friend had Cambridge Soundwerks speakers in his very small apartment, and I was shocked at how good they sounded. Two little cubes and a big square subwoofer. At the time, he said they were expensive, and that didn't surprise me. What's out there now? I don't mind shelling out for the Good Stuff-- not quite studio monitors but close--, as long as they can run off of 12v and they are small. -ken

Will there be a list of nearby hotels posted on lac.linuxaudio.org ? I'd like to be able to book in advance. Cheers, __________________ Marc-Olivier Barre, MarcO'Chapeau.
