Hi I'm about to release "an actual CD" made only with linux tools. For the mastering I lined up all "tunes" in ardour on on each track, and set the locations for each tune. I read this: http://www.ardour.org/files/manual/ch-exporting.html and it suggests that I leave a 2 seconds space before the "first modulation" (what ever that is), which made me align like this: http://atte.dk/download/ardour.png. When I export (with toc) and burn using "cdrdao write modlys.wav.cue" the CD plays just fine, but (and this is the whole point of this mail) when I rip it again with cdparanoia I get a silent track00 that lasts 2 seconds. Obviously I'm not interested in this this behavior on my final CD, and am wondering what I did wrong. Any thoughts? -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk

[ANN] jackmix 0.4.1 released

by Arnold Krille

Just a quick note about a quick release: JackMix 0.4.1 is out! Get it from http://www.arnoldarts.de/drupal/?q=JackMix%3Aintro or directly via http://www.arnoldarts.de/drupal/files/downloads/jackmix/jackmix-0.4.1.tar.gz This is "only" a buildsystem release. But now it should work. The detection of the qt-specific compilers (moc/uic/rcc) should not be a problem anymore. Building also got easier, it is just calling "scons" and watch for everything to happen by itself. Except for installation. You currently have to copy the binary by hand to your destination of choice. But its only that binary that is needed. For those who don't know (and don't want to look at the above mentioned website), JackMix is a small but powerful mixer for jack, featuring a configurable number of inputs and outputs, providing a NxM mixing-matrix and allowing to combine these mixing-nodes into bigger ones with other controls. So you can combine some nodes to become for example a 2in-2out stereo node. Its hard to explain, look at it for yourself... Probably some of my other pets will also see a minor-release the next days with the same changes to the buildsystem, so if you run into any problems, just let me know! Have fun, Arnold -- visit http://www.arnoldarts.de/ --- Hi, I am a .signature virus. Please copy me into your ~/.signature and send me to all your contacts. After a month or so log in as root and do a "rm -rf /". Or ask your administrator to do so...

JACK Midi

by Arda Eden

Hi, I generally use Alsa MIDI support on most of the music applications. But with Jack Rack, in the MIDI settings dialogue i cannot see any MIDI devices in the list. And when i try to run QJackControl with Raw MIDI support jackd cannot start. What can be the problem ? -- Arda EDEN Cumhuriyet University Faculty of Fine Arts Department of Music Technology

LAC 2008: live online Now!

by Eric Dantan Rzewnicki

The 6th annual Linux Audio Conference has begun in Cologne, Germany. It runs today through March 2nd, 2008. As with each previous year this year's conference is streamed live over the internet in ogg theora via icecast. The stream status page can be found at: http://lac.linuxaudio.org This year we are in the unique situation of having a Gigabit link donated by CITIZENMEDIA: http://www.ist-citizenmedia.org/ They have asked us to use up as much of their bandwidth as we can so they can see how well the link performs. Please forward this information widely so we can help them out. This year the core team, Joern Nettingsmeier and myself, are recruiting volunteers to spread the workload. To that end we have set up a mailing list and irc channel to coordinate our efforts. If you are here in Cologne for the conference please consider joining us. If you are not coming, please enjoy the fruits of our labors by watching the streams and participating via irc. stream team mailing list: http://zhevny.com/mailman/listinfo/lac-streams general conference chat: #lac2008 on irc.freenode.net stream team tech talk: #lac2008-tech on irc.freenode.net Thanks, LAC streamteam -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Re: [LAU] RT error?

by Norval Watson

What would be a good number for memlock with 4G RAM? I've got it set at 3145728 which is 75% of available RAM but I still get startup warnings from Ardour and bad_alloc crashes with some apps. Should I set memlock at 4000000? Norv Get the name you always wanted with the new y7mail email address. www.yahoo7.com.au/y7mail
