[linux-audio-user] Help Needed: sys admin

by M P Smoak

Upfront: Not free help. I don't have time/skill to do what needs to be done. It's worth money to get it done now. I'm needing a person to help me configure a couple of systems via ssh and email/phone. I've looked locally without success. Probably best to have someone with an interest in linux audio, so I'm looking here. Systems: 1. My PlanetCCRMA/RH9 system; going to ??? soon. Probably Planet/FC3. On this machine I need some scripts, setup/use of audio app's, etc. I've learned alot about running a linux workstation, but I just don't have the time right now to a do the work myself. 2. I have a debian server that I'm setting up as a TWiki. The TWiki is installed and now needs to be configured/customized. Work involves talking to the techs at the server provider and a University, compleating the configuration and assisting in the customization. I'm trying to keep both systems simple. Well away from the bleeding edge. If you're interested send email to: "Pem"<smoak(a)mis.net> Ability to handle a remote system via ssh is essential. Experience with scripting, Jack, ... I want to get started on this now and complete the work on sys2 this summer. Helping me with sys1 could be a regular thing for a longer period. Thanks, Marv in Lexington, KY

Anyone using qsynth on an AMD64? I am having troubles getting it to work and am wondering if it is a 64 bit compat issue.

According to Richard the deps should all be handled by the static binary. I've got it making sounds now after a faulty start (my fault). I'm going to try it out on sarge. Did you have to build a deb package from the source-code, or will it run off the shell script in the static binary?

[linux-audio-user] light multitrack recording

by Peter Lutek

greetings! i'm wondering what you all would recommend as the least resource-consuming (in terms of cpu/memory usage) method for multitrack recording. i need to record 18 channels (each to its own file) of 44.1kHz float audio in a live setting, while simultaneously running some looping and FX, so i'd like to keep the recording chain as lean as possible. curiously, my tests have shown significantly lower average system load using ardour than using ecasound. i was surprised by this, having assumed that ecasound would be the solution. so now i'm wondering if other options might be even better than ardour. maybe a recorder built in pd? i do need metering, preferably with resettable peak indicators. thanks, in advance, for any advice or suggestions! -p

What is a good tool that allows you to redraw and otherwise alter a wave form by hand? I'm having trouble finding one.

Taybin Rutkin is the author. Oh, I see. I thought he did. Anyway, I found the problem. I had to upgrade DB. It could be that gentoo applied some patches to it as well. DB is the one that didn't have any AMD64 code for fast mutexes. It works now, or at least seems to so far. The GUI could /definately/ use some work and it would be nice to be able to send session information as well as download it. To many things in the way that can cause problems to make a really good test. My modem may or may not be port -forwarding, the GUI says 'lost connection' whether it finished or blew up. It is confusing us. But this is a 0.1 release so it isn't expected to be exactly easy to use or do everything we want. It is a great idea though.

Taybin Rutkin is the author. I just tried firing it up with these installed: python-devel-2.3.4-13.1 python-2.3.4-13.1 python-twisted-1.3.0-1.1.fc3.rf Everything is working. I didn't catch what version of twisted you are using but maybe it's that simple. Taybin occasionally shows up on IRC at server: freenode.net on channel #ardour. If I see him I'll let him know you sent him a mail requesting some help. ron > Sampo Savolainen <v2(a)iki.fi> > > __________________________________ Do you Yahoo!? Yahoo!

[linux-audio-user] ANN: Oscilloscope plugin 0.2.0

by Lars Luthman

Here is an oscilloscope DSSI plugin that I've been hacking on the last few weeks: http://www.student.nada.kth.se/~d00-llu/music_dssi.php?lang=en It has two audio input ports and will display the two input signals as two waves in the display. The trigger level and direction is controllable, as well as the amplification and offset for each channel and the time resolution. Note that this plugin will NOT work with jack-dssi-host from version 0.9 of the DSSI package since that does not support audio input ports. It will work with jack-dssi-host or Om from current CVS (I haven't tested it with Rosegarden). Om 0.1.1 and earlier will not work because of an optimisation that breaks this type of plugins. The plugin includes a DSSIUIClient class that might be of interest to plugin UI writers using libsigc++ and Glibmm - it handles all the required communication with the plugin host and exposes public member functions and signals for the UI -> host and host -> UI OSC commands specified in the DSSI RFC. It can also handle the nasty business of setting up an initial shared memory segment for the plugin and the UI (the actual implementation of the shared memory handling is in a separate C file, so it could be useful for people who don't use libsigc ++ and Glibmm or even C++). Source code documentation is here http://www.student.nada.kth.se/~d00-llu/plugins/ll-scope/dox/html/classDSSI… and here http://www.student.nada.kth.se/~d00-llu/plugins/ll-scope/dox/html/dssi__shm… For more details about the plugin, read the README file in the source package. It's all GPL. -- Lars Luthman PGP key: http://www.d.kth.se/~d00-llu/pgp_key.php Fingerprint: FCA7 C790 19B9 322D EB7A E1B3 4371 4650 04C7 7E2E
