[LAU] Soundtrack from recorded TV

by lanas

Hi all, I recorded this fabulous movie from the 1920s, "Faust" by German filmmaker Murnau, as it was shown on TV. It has a fabulous soundtrack which is akin to bands like Univers Zero and Art Zoyd but in a lighter mood so to speak. Even perhaps an enriched version of The Residents. In short, it's a good listen and a good inspiration for meldoci and rythmic moods. Moreover, according to IMDB it seems there are several soundtracks, so it could be unlikely for me to rent the exact same DVD. I could load the recorded track into Kino and save only the audio (I guess - I never did it yet) but that takes an awful lot of time because Kino will have to convert the file and the movie last about two hours, so that's a lot of processing time. My question is, is there an utility out there that will separate the audio from the images of a recorded track and record the audio in a separate track (possibly at a higher speed than regular viewing) ? Thanks for any suggestions, Al

Re: [LAU] Music - Skype and idjc on 64-bit

by Norval Watson

Hi Rick, Thanks for quick reply! I tried your method (below) but got the same error message about not finding the shared object ALSA lib pcm.c:2106:(snd_pcm_open_conf) Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_jack.so This happens whether JACK is running or not. The problem seems to be triggered by using the .asoundrc file, when I delete that and restart skype in standalone mode its ok. I suspect its 64-bit related and I'm missing a link of some sort...? Thanks again Norv QUOTE: "I use skype via jack alsa plugin, idjc works, debian lenny 32bit, no idea if your situation is related to using 64 bit or not. Also, you dont need idjc to play music over skype. You can create your own PCM device in .asoundrc to use the jack plugin, and configure skype to use that device. Then in qjackctl you can connect the relevant capture ports to the skype PCM playback ports. Here's my skype section of .asoundrc: pcm.skype { type plug slave { pcm "configvoip" } } pcm.configvoip { type jack playback_ports { 0 alsa_pcm:playback_1 1 alsa_pcm:playback_2 } capture_ports { 0 alsa_pcm:capture_1 1 alsa_pcm:capture_1 } } I simply use the "skype" device in skype sound device config."

[LAU] Music - Skype and idjc on 64-bit

by Norval Watson

Hi, I am trying to get Skype working with idjc (Internet DJ Console) so I can play music on Skype. I run debian sid amd64 on AMDX2 dual-core. I got standalone Skype Beta 2.0.0.27 (static version) working with webcam. I followed this Ubuntu guide http://ubuntuforums.org/showthread.php?t=577914 to get Skype playing with idjc and JACK but its written for 32-bit. I compiled idjc (64 bit) ok using this page http://www.onlymeok.nildram.co.uk/download.html with plain ./configure command. idjc starts ok, loads, plays tracks ok. When I start Skype from the terminal I get ALSA lib pcm_dmix.c:866:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm_dsnoop.c:558:(snd_pcm_dsnoop_open) unable to open slave ALSA lib pcm.c:2106:(snd_pcm_open_conf) Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_jack.so (repeats many times) I think/hope I got all deps and build deps including lib32asound2 and lib32asound2-dev and I definitely got /usr/lib/alsa-lib/libasound_module_pcm_jack.so on my system. I got ia32-libs. Do I need linux32? I already have a 32-bit chroot. Any help appreciated! Norv PS: When I Skype my bro in California from Australia we get a time lag between 0.5 and 1 second so live jams are not on :( Make the switch to the world's best email.

[LAU] [ANN] klick 0.5

by Dominic Sacré

Hi all, klick has been around for almost a year, but I figured no one will know about it if I don't tell anybody. So here's a new version, and the first official announcement. klick is an advanced command-line based metronome for JACK. It allows you to define complex tempo maps for entire songs or performances. Its features include: * Support for tempo maps, including arbitrary meters, tempo changes, accelerando/ritardando and more. * Three built-in sounds (borrowed from Ardour, GTick and FreePats), plus ability to load your own samples. * JACK transport sync support (master/slave). * No GUI ;) Get it here: http://das.nasophon.de/klick/ Cheers, Dominic

[LAU] Marrying MIDI with Music

by Charles Linart

Hello everybody. Have been experimenting lately. Reared on dear old Dad's Radio Shack cassette recorder and vanilla four-track analog recording, I've always been pretty much a straight-shootin' audio guy. Linux audio has opened up new worlds to me. Nowadays, I'm getting into MIDI, and while I still think it stinks as a general rule (takes the humanity out of music IMHO), I can see its utility. So I've been working on getting audio and MIDI channels to play nicely together through JACK, and I finally got it down (at least the basics). The long-term vision is to have a band jam live in pure audio as a MIDI engineer sets down a fresh electronic groove, something like what the Talking Heads did live but with a 21st Century twist. My first effort was just a technical experiment to get everything plugged in. It's no great composition, but it brought the vision a little closer to reality. The mix was a quickie, as was the "song" itself -- took longer to plug everything into JACK than it did to actually record and mix. This won't sound like much to many of you pros and old hands, but it represents a major breakthrough for me. Since lam.fugal.net is down for the count, here it is. Feedback would be appreciated, but please be gentle in your criticism as I am a novice and a sensitive type. http://charliehiphop.com/audio/download/226/newexperiment.ogg If you want more details on how it was done, check this http://charliehiphop.com/new_experiment_ogg_download Enjoy, and thanks!

[LAU] vst presets

by James Stone

Does anyone know of a program that will allow use of vsti under linux that also utilises the built in presets for the instrument? So far I have only been able to load the vsti parameter change gui using things like fst or dssi-vst, but no way to load or save presets. am I missing something? james
