Hi everyone, I spent some time researching a bunch of tools and approaches to linux audio backup and found one that's workable even if you're lazy. Here's the write-up: http://carlocapocasa.com/backups-for-ubuntu-linux-audio-recordings (permanent link) Hope it's useful! Carlo

Call for music -- LAC 2012 video-trailer soundtrack

by Robin Gareus

**Create a soundtrack for the LAC 2012 video-trailer** We are going to prefix the video-recordings of this year's LAC with a short trailer. Currently it is silent: http://vimeo.com/37900660 What better source is there for the Linux-Audio-Conference-Sound than the Linux-Audio community itself! It's on rather short notice, but it's just 8 seconds long. Details to answer the call, as well as information about the video can be found in README.txt that accompanies the video-file: http://download.linuxaudio.org/lac2012/ looking forward to /hear/ from you, robin

splitting video/audio and recombining

by James Stone

Hi List, I have a video which needs a bit of eq'ing on the audio side. Can anyone point me in the direction of how to split the file into audio and video so I can apply some treatment to the audio, and then combine them back together again? The video is wmv at the moment, but mplayer doesn't seem to have any problem with it. James

jack-mixer questions

by didgewind

hi there. I'm trying to set up jack mixer to be controlled with a korg nanokontrol 2. I'm using ubuntu natty and jack mixer version from the repositories. First problem i'm facing is that jack-mixer uses jack midi and nanokontrol uses alsa midi. I kind of solved it running jack with raw or seq midi driver, running a2jmidid and connecting nanokontrol to midi through and wrapped a2jmidid midi through to jack mixer. Don't know whether there is an easier way. Second problem, i can only assign midi channels when creating the input and output channels. If I try to edit any of the channels, the name of the channel dissapears and the midi assigns get lost. I tried to compile jack-mixer from the scratch, but the behaviour remains the same (and now i don't know how to uninstall jack mixer, by the way, 'cause it doesn't show up in dpkg nor synaptic package manager). Third problem, by default master channel is assigned to midi input 11. That's handy sometimes, but not when u are using two different instances of jack mixer, one to mix the instrument i am playing with the synthetizer, routing everything to sooperlooper, and the second to mix this output with some other music and hydrogen. In this case the same hardware slider is moving both master channels, no handy at all. so, any help with any question would be greatly apreciated. -- El viento y el arcoiris guían mis pasos http://revistavicaro.blogspot.com didgewinD

Hello, Is there such a thing as a CLI programme which might return the average perceived loudness for a given audio track? Cheers, S.M. --

If your distro don't provide the nv driver, but replace it with an experimental driver, that knowingly isn't working for half of the NVIDIA graphics on the market, such as the nouveau driver, than your distro is borked! OTOH, for Debian it's easy to build kernel packages yourself. Doing that, offend the license: sed -i \ 's/EXPORT_SYMBOL_GPL(migrate_enable);/EXPORT_SYMBOL(migrate_enable);/' \ kernel/sched.c sed -i \ 's/EXPORT_SYMBOL_GPL(migrate_disable);/EXPORT_SYMBOL(migrate_disable);/' \ kernel/sched.c sed -i \ 's/EXPORT_SYMBOL_GPL(__rt_mutex_init);/EXPORT_SYMBOL(__rt_mutex_init);/' \ kernel/rtmutex.c > ------------------------------ > > Message: 5 > Date: Wed, 22 Feb 2012 19:04:48 +0100 > From: "rosea.grammostola" <rosea.grammostola(a)gmail.com> > Subject: Re: [LAU] Linux 3.2.0-rt Kernels on Debian Repos! > To: linux-audio-user(a)lists.linuxaudio.org > Cc: Debian Multimedia Maintainers > <pkg-multimedia-maintainers(a)lists.alioth.debian.org> > Message-ID: <4F452E40.6090004(a)gmail.com> > Content-Type: text/plain; charset=ISO-8859-1; format=flowed > > Cool! All though we don't really need -rt anymore afaik. Lowlatency > would be good enough. I build, but never tested a full preempt kernel with threadirqs set. Anyway, this already was claimed for preempt enabled kernels before 2.6.29 and at least at this time it wasn't true. Depending to your workflow and your cognitive ability, you might wish to get less audio latency with hard real-time MIDI jitter. People often blame MIDI of not being capable to do some things. I recommend to get rid of ms of jitter and to use several PCI MIDI interfaces, before claiming that MIDI shouldn't be able to do something. IMO a rt patched kernel is a step into the right direction to get hard real-time. 2 Cents, Ralf

DSSI/OSC problem

by Julien Claassen

Hello everyone! I've just started hexter again, with its text_ui. The synth and the UI come up OK, but I can't send any command to the synth. I've been trying with oscsend and the dssi_osc_* commands, but nothing happens. Any idea, what I might check or what the problem might be? I'm a gonna. As pretty as this electric piano is, I'd much rather have a choice of sounds. :-) Warmly yours Julien =-=-=-=-=-=-=-=-=-=-=-=- Such Is Life: Very Intensely Adorable; Free And Jubilating Amazement Revels, Dancing On - FLOWERS! ====== Find my music at ====== http://juliencoder.de/nama/music.html .....................................
