EMU 1212 - internal routing for ADAT in

by Julien Claassen

Hello everyone! I've just got an analog to ADAT converter, but I'm having difficulties. Now I wish to eliminate routing problems on the card. I can only do it in alsamixer. So if someone has a similar card with an ADAT-input, I would very much appreciate a description of your alsamixer output for the ADAT items, as well as the DSP items for output. I'm not sure, how much those interact. Warm regards Julien ---------------------------------------- http://juliencoder.de/nama/music.html

linux compatible USB Audio Interface

by profiles

Hello, I am a musician and recently joined this mailing list. I use Fedora18 and would like to use it to create music. I am having trouble getting off the ground as I have not identified a USB Audio Interface that is compatible with Fedora. I have visited the ALSA soundcard matrix wiki and a number of forums in hopes of finding a device. Unfortunately many of the models and makes talked about are a few years old now and, frequently, are no longer available from distributors. I imagine a few people on this list use some sort of soundcard to test/use all of the great software that is being created for linux users. I am inviting suggestions from people with experience in the application of audio hardware in the fedora environment. I am looking for a device that uses an independent power plug, connects with usb 2.0, and has both MIDI and analogue inputs and outputs. A device similar to this would be great: http://www.presonus.com/products/AudioBox-44VSL/media Thanks and I look forward to offering feedback on software once I am up and running. -Occhi

How to finalize and make movie DVD

by Abhayadev S

Hi, I have been using the US mainly for audio works and now planning to leverage it for mixing BGMs for movies and quite not sure the techniques involved in finalizing the audio and video (HD/SD) in to a DVD or similar output formats for release. Anybody out there would like to share some experience and tools available for this? Regards, Abhayadev S

Using a USB pedalboard to trigger keystrokes

by Julien Claassen

Hello everyone! Someone told me, that they were intending to get a pedalboard to trigger keystrokes to control some commandline applications. And I've been wondering. Does anyone have experience with that? A specific device and what about the configuration tools for such tasks? I've been searching the web a little, but unfortunately keyboard, pedalboard and the like are very ambiguous search terms, so the results were rather unhelpful. Any ideas would be welcome. Since I can't solder myself, I'd prefer prebuilt solutions. I'm pretty sure, that this would be possible with Arduino based solutions, but I'd rather not for a start. :-) Warm regards Julien ---------------------------------------- http://juliencoder.de/nama/music.html

VST on Gentoo

by Brent Busby

I notice there doesn't seem to be any Vestige package in Portage, not even in the Pro-Audio overlay, but there is FST and VST-DSSI. What's the typical way for Gentoo users to get VST support these days? Never really cared before, but I'm think of checking it out now. Also, I notice that compiling Ardour with VST support throws up a warning about trying to enable it on a 64-bit host being an adventure of sorts... Any common strategy amongst Gentoo folks for doing that? -- + Brent A.

Screencasting with JACK [SOLVED!]

by J. Liles

As some of you may recall, every time I've posted a demo video to LAD, I've had to include a disclaimer excusing the poor quality due to a lack of functional screencasting tools. Well, it took a couple of weeks of hair pulling and many, many hours of testing, but I finally arrived at a solution. Anyone who wants to create a screencast and record audio via JACK *in perfect sync* must do the following: Get ffmpeg. Apply this patch to it: https://github.com/original-male/FFmpeg/commit/d02509d04d396a98646ca81e9ba3… Build it with vorbis and h264 support. Then, start your favorite desktop environment. I use Xephyr for this. Have jack running (at -r 48000) Then run the following command: ffmpeg -fflags +genpts+igndts -f x11grab -vsync 0 -r 30 -s 1920x1080 -i :${DISPLAY}.+0,0 -vcodec h264 -f jack -ac 2 -r:a 48000 -i screencast -acodec pcm_s16le -r:v 30 -vsync 2 -async 1 -map 0:0,1,0 -map 1:0 -preset ultrafast -qp 0 "$FILE" Where DISPLAY is the number of your X11 display and FILE is the filename for the screencast. I use a .mkv extension for the matroska container. Remember to connect the streams you want recorded to the 'screencast' JACK inputs! With this setup I'm able to record a full 30 FPS @ 1080P with audio in perfect sync. Please share your results too. With some more evidence I might have a good case to get ffmpeg to accept my patch. Enjoy!

Decompressor for linux?

by Ken Restivo

It's been a while since I did anything with linux audio, or even had much to do with music, but now I'm attempting to listen to music that has been recently released, and find it unlistenable. The mastering! The compression! It burns!! It burns!!! Auugh, my ears!! I mean, it's obviously distorted. I can hear the clipping. People are putting out released tracks that I can't listen to without getting a splitting headache. Is there any such thing that I might be able to pipe into an ALSA or JACK setup, which would repair these broken tracks? It's sad. It's like people are mastering for laptop speakers, cellphone speakers, or earbuds, and nothing else. FWIW, as an example, I've just stumbled across the music of Amanda Palmer, downloaded her latest album, I think the music is great, or could be, but I can't listen to it because of the mastering. -ken

Re: [LAU] sortof OT -- ART tube pac preamp and compressor noisy?

You need to be more specific, nobody can help you otherwise. The delta 1010lt has two mic inputs with XLR connectors. Is it one of these you are using ? It is probably configured for maximum gain and you need to change that. It's done using jumpers on the card, see page 8 of the manual. First try the setting marked '2A' in the manual. If you can't get enough signal (by increasing the gain on the preamp) with that, try '2'. If still not enough, try '1A'. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities. (Cory Doctorow)
