After reading that last post about the distributed studio[1], it made me think of how network transfer of 40 channels of audio into and out of up to 6 machines is possible. As a simple test, I wired 2 machines over a 10/100Mb connection, private network, 1 router and 1 switch. I fired up the tools as described in the how-to[2] then opened up xmms, wired it to netjack (on the client) and routed the server netjack to my main outs... sounded great! until I noticed xruns occasionally. So I guess my question is simply: is netjack2 really that capable and if so, what are the tweaks involved to get seemless audio using it. Does anyone here use netjack2 ... and if so, what is the primary purpose? thanks David [1] http://www.itwire.com/opinion-and-analysis/open-sauce/36698-from-windows-to… [2] http://trac.jackaudio.org/wiki/WalkThrough/User/NetJack2

Audio app which supports RT Jack Transport bpm changes

by rosea grammostola

Hi, Is there an audio app which supports Jack Transport bpm changes in realtime? I know some midi apps like hydrogen and non-sequencer, but not audio apps which can play and/or record audio. Regards, \r

Two (free) albums (free) tracks available on archive.org

by Aurelien

Hello, (pre-prost-scriptum: improtant informations are quite below!!!) I think I didn't any announcement here before, but the label I created some years ago, and work in by now, released two albums fully realized with free softwares (on a Debian GNU/Linux distribution) in 2008: Sebkha-Chott - Nigla[h] / Tapisseries Fines en XXX Strips et LXX/X Trompettes Sebkha-Chott - De la Persistance de la Mythologie Chottienne en ??? Vélos Both those albums are distributed internationally by the label Muséa Records, and you may find them, freely downloadable and/or to purchase here: www.ammd.net/productions/productions.php and at a lot of other places on the web. You also might find numerous review of those albums, in Google, and so on. OK, that's it for the presentation. Actually, it took us a lot of time, but we finally sent the whole tracks of the 14 multitracks session (in ardour) and the session them selves on archive.org, so that you can use them freely. it's quite big big big sessions, as Sebkha-Chott used to be 8 people at that time and invited something like 25-30 guests to play with. So you might find something like 100-150 (even 180 on one of them, if I remember well) tracks by song. For Nigla[h], there are two options: we did tarball of each ardour sessions directory and we also bounced every tracks in one file, so that you can manage to use them in another multitrack editor. We then thought about it, and had the conclusion that it was a really hard work for us to do all these bounces and exports, and finally it essentially was destined to people using proprietary softwares. So, for De la Persistance, you will only find the tarballs, as we think we have to "encourage" people using ardour, or, if they prefer ecasound or whatever, they probably will be skilled enough to convert the xml file into something suitable for another soft, or a bit worse, they always might do all that export stuff and so on. The archive.org links are listed on www.ammd.net/productions/productions.php Hope you will enjoy it. All our further productions will follow the very same line (there will be one recording session in November for a pop-prog-rock band), and we also aim to release some very huge instruments sample base, as we have the luck to possess a very good studio, and also very good instrument, including, for example, a true Harpsichord, as one of us do build Harpsichords! See you. Aurélien - AMMD www.ammd.net PS: For off-list further informations, please write to orlATammmmmmmd.net, which is my pro mail, which I don't want to subscribe on this list (and ammd does spell with two 'm' only! ;) -- Aurélien

Re: [LAU] ambiophonics vs. ambisonics?

by Martin Leese

J?rn Nettingsmeier <nettings(a)folkwang-hochschule.de> ... > and there's an excellent MAG article about using 4 speakers for better > stereo replay here: > http://www.audiosignal.co.uk/Resources/Surround_sound_from_2-channel_stereo… > nothing to do with ambisonic decoding, though. This is just the old Hafler circuit. It doesn't really compare with Ambisonics. Gerzon's contribution to the Hafler circuit was the addition of a blend or rear spread control between the rear speakers and ground. This is described in his later article "A year of surround-sound", also available at The Gerzon Archive: http://www.audiosignal.co.uk/Gerzon%20archive.html The Hafler circuit is also available at: http://members.tripod.com/martin_leese/Audio/ Regards, Martin -- Martin J Leese E-mail: martin.leese stanfordalumni.org Web: http://members.tripod.com/martin_leese/

Fractally fuzzy music?

by david

I've thought about a "music" in which notes might have "fractal fuzziness" to them - for example, what looks like a quarter note is really 8 simultaneous (or non-simultaneous) 32nd notes, each having a frequency that is some fractally-derived distance from the base quarter note's frequency, and perhaps their timing/duration could also be fractally derived ... I don't suppose someone knows of such a thing already being done? -- David gnome(a)hawaii.rr.com authenticity, honesty, community

ardour muted

by Andras Simon

Sometimes ardour, while otherwise working perfectly, goes completely mute. Reconnecting to jack or restarting doesn't help. What should I check or change? (I'm using version 2.8.4 on Fedora 10 with no PulseAudio.) Andras

Jack included in Main for Ubuntu Lucid Lynx

by Fritz Meissner

I'm not sure if this is old news to others, but I just noticed that jack has been approved for inclusion in main for Ubuntu Lucid Lynx; this means that now PortAudio can be built with support for jack and we hopefully will be able to have a distro that "just works" for serious sound (although there is still some discussion about kernels). Details are here : https://bugs.launchpad.net/ubuntu/+source/jack-audio-connection-kit/+bug/51… Congratulations to the Ubuntu Studio team - it's nice to see that the work and pressure to improve Ubuntu audio is paying off.

OT: linux video?

by Aaron L.

Hi all. It's been interesting to read about everyone's various setups and I noticed a few people mention that they're using ArtistX. Is anyone actually using it for video editing? And I don't even mean "pro" video editing. I'm just wondering about video editing period. I've been using UbuntuStudio for the past couple of years and the video editing software that came with it leaves much to be desired. Just curious if anyone's actually producuctive with anything video and linux related. Thanks. -Aaron
