[linux-audio-user] Xitel Pro Hifi-link playing mono, not stereo (Fedora Core 6)

by martin

Hi, I have a Xitel Pro HiFi-link usb soundcard which works fine in Linux, except that it appears to be sending the same signal to both left and right channels. If I start up e.g. Audacity, import a track and pan it all the way to the left or right it still plays in both channels. The same thing happens in Ardour so I don't think it's a software specific thing. I've had this problem in FC5 and FC6. The sound was fine before that (FC4 I think). This is my first time playing around with Linux audio so if anyone could suggest how to start fixing this I'd be grateful. I can post any log/config files. Thanks, Martin

[linux-audio-user] rebuilding the linux soundapps site

by Dave Phillips

Greetings: I've received a few notes that indicate people are interested in revising the look & feel of the site at linux-sound.org. If you're currently working on such a project *please* make your intentions public. There are at least two projects working towards the same end, and this is truly one wheel that does not need reinvention. Better that folks work together on it. Best, dp

I get the impression he didn't think particularly >highly of either of them after his workflow was interrupted so suddenly. > Actually, "git" is a swedish word meaning something like "extreme posession", or wanting something very bad. Its a word thats used frequently to describe the devils wish for souls. Quting from the online dictionary http://g3.spraakdata.gu.se/saob/ on "git": "BETYDELSE: frö av svartkummin." Betydelse = Meaning Frö = strong desire av = to have svartkummin = evil desire ("svart"=evil and "kummin"=desire) And since Linus' native language is swedish, my guess is that this is his funny way to say that he has an evil desire to spread linux all over the world. Well, thats just my theory. :-)

[linux-audio-user] first track made with Linux audio tools

by Yo

Hi Linux Audio users, Here is an extract of the first track I have mixed with a friend in my home studio. As it is my first track (and first try!), I am very proud of it, even if it's rather minimalist and very far from perfection..! If you have time, please listen it and give me our feeback on what could be improved, added, changed according to you... I am a beginner but very motivated to learn! Some details on how it was made: Voice recorded with an AKG C4000B Guitare recorded with a static AKG microphone (C1000S) M Audio 24/96 soundcard Acoustic bass recorded through a V-Amp. Ardour A piece of reverb on voice and bass Hydrogen Jamin http://www.xrousse.org/index.php?idArbo=mao_libre&view=viewone&id=19 Enjoy! -- Yohann http://www.xrousse.org | mailto:yo@xrousse.org | MSN yoyo(a)xrousse.org | GPG: 0x43D83E36 C'est toi le nouveau ?

[linux-audio-user] Squeak Audio

by Brad Fuller

Cesare Marilungo wrote: > It's a pity that the audio (an in general the multimedia) aspects of > squeak have been left behind in recent development. Hi Cesare, I agree. It can be so much better. As you know, I made a call out to Squeak developers and a few replied regarding refreshing the multimedia side of squeak. But, you know, maybe I asked the wrong people! Most of the developers on the main squeak development list focus on more basic fundamentals. I should have made the call here. I would love if audio developers here would get involved in squeak! Think of how fast and how cool some of those apps would be! Squeak has many benefits for audio developers: 1: you can take advantage of all the great features of Smalltalk. Too numerous to list here - the late binding facilities of smalltalk is one important perk. Great for development and for deployment. See: http://squeak.org/Features/Development/ For any competent programmer, the smalltalk syntax can be learned in an hour. To take advantage of the classes takes much longer. 2: Your application will, in most cases will be available on Windows Mac and Linux immediately. (unless you write a VM plugin which you'll have to port) 3: It already has many audio facilities already completed (as I mentioned, ALSA plugin is in the latest 3.9 VM.) Some of them need cleaning up, and that would be a great way to start learning the classes for audio. 4: there are many resources at your disposal - from the rich Smalltalk environment to the Wiki's and development mailing lists. Please chime in, Cesare, with your experience with pd, OSC and squeak. -- brad fuller http://www.Sonaural.com/ +1 (408) 799-6124

[linux-audio-user] [ANN] GLASHCtl 0.4.0

by Lars Luthman

This is a simple applet for controlling the LASH Audio Session Handler. When you run it it will appear as a small LASH icon in your "notification area" or "system tray" (if your desktop manager is compatible with freedesktop.org's "System tray" standard, http://www.freedesktop.org/Standards/systemtray-spec). This is typically somewhere in the panel in KDE or GNOME. There is also a front end for the WindowMaker dock (or compatible window managers). Changes since 0.2.0: * A DockApp front end (thanks to Nedko Arnaudov) * A "Recent" submenu for restoring recently saved sessions * A "Connect" submenu for connecting and disconnecting JACK ports * Doubleclicking session directories in the file selection dialog restores the session instead of going into the directory * The message window is removed Get it at http://dino.nongnu.org/glashctl -- Lars Luthman - please encrypt any email sent to me if possible PGP key: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x04C77E2E Fingerprint: FCA7 C790 19B9 322D EB7A E1B3 4371 4650 04C7 7E2E

[linux-audio-user] ecasound question with RME hammerfall lite.

by Stephen Cameron

I'm trying to record multiple tracks at once from my RME Hammerfall lite, just to transfer from my AW4416 to PC, the stereo tracks are already recorded on the AW4416, I just want to transfer them both at once. Is this the right way to do it? ecasound -r -c -a:1,2 -i jack -o guitar.wav -a:3,4 -i jack -o drums.wav Then, type "engine-launch" to ecasound, then (via qjackctl) connect RME capture channels 1-4 to ecasound inputs 1-4 (assuming audio is coming in on channels 1-4). Then type "start" in ecasound, and start playback on the aw4416. So far by this method, I'm capturing only silence, but I suspect this is a mistake I'm making on the AW4416 with routing audio to the ADAT outputs. Just want to make sure I'm using ecasound in the correct way to accomplish what I'm trying to do. -- steve ____________________________________________________________________________________ Do you Yahoo!?
