[linux-audio-user] laconf2 call for help w/ irc and streaming

by Joern Nettingsmeier

hi everyone! as you will certainly have heard, we are getting closer to the 2nd linux audio conference at zkm (http://www.zkm.de/lad). as you might also have heard, we will have live streams of all talks and lectures in ogg format for those who can't make it there in person. last year, we had an irc "feedback channel", meaning i would sit in the lecture room with a notebook, answer questions from people who were listening to the stream and relay their questions to the audience if necessary. i want to do the same this year. problem is: there are three lecture rooms now. so i'm looking for a couple of people who'd be willing to help out. specifically, i need people who * are at the conference :) preferably the whole time * bring their own laptop with working sound output and headphones * have some experience with networking * have or can operate a webcam on their machine and are willing to install xawtv * like to chat your tasks will be: * to attend talks * to have an irc window open and answer and relay questions * to set up a webcam that will provide the listeners with stills so that they'll know which slide is up atm etc. * to monitor the outgoing stream and to ping the relays from time to time. the more helpers, the less work for all of us. last year, it has been great fun, although chatting, monitoring (with some 5 seconds lag) and listening at the same time can make your head spin in funny ways. please cc: me privately on any replies. thanks. regards, jörn -- Jörn Nettingsmeier Lortzingstr. 11, 45128 Essen, Germany http://spunk.dnsalias.org (my server) http://www.linuxaudiodev.org (Linux Audio Developers)

Just go into the Makefile and remove "-Werror" from line 71. That might "solve" other potentional compiling problems as well. --

Re: [linux-audio-user] switching from windows + cubase

by davidrclark＠earthlink.net

Thomas, You said that you were "considering" switching to Linux for audio. If I were interested in doing *only* what you mentioned doing, I would myself not move to Linux audio. However if you have *other* reasons, then you may have a good argument for switching. I should say that I'm making these statements as someone who detests Microsoft and Windows, so it's not easy for me to recommend Windows for what you plan to do. I myself do Linux audio programming because I'm doing more audio research than music per se, and I wouldn't perform serious technical tasks any other way. However, in good conscience, I myself cannot recommend Linux audio for the task you described any more than I could recommend that my brother-in-law replace all his Windows business software with Linux. If you don't have time for Debian or Gentoo, then you may not have time for Linux audio. Perhaps you already know this, but many people don't: Linux isn't about free software, it's about USER-SUPPORTED software. This means you contribute to your own support as well as the support of others. Now if you insist on going all-Linux, you've come to the right place. The people here are very helpful.

[linux-audio-user] switching from windows + cubase

by Thomas Pickett

Hi, I'm considering switching for Windows to Linux for my audio stuff. I have a few questions. 1) I have some Cubase projects, and I mostly care about the midi sequencing. If I export them to midi files, will I be able to restore most of the information in Linux? 2) This is my first install. Can you suggest a distro for a 1.6 GHz Athlon machine that would be good and stable for audio yet not be too hard to set up and get working? Preferably something with a 2.6 kernel. I was going to go with Mandrake, but I really don't know. Definitely something like Debian or Gentoo is too involved for me right now. 3) I have a Soundblaster Audigy. Should I look into getting a new soundcard? What is a good internel or external box that is supported well? 4) Can you recommend a set of software that will be enough to get started with? I know that there are many many options and I would just appreciate a little direction so I don't get discouraged. I just want to record vocals, record midi and use my synthesizer, mix them together, and process it all with some plugins. That's all, and thanks for any information.

[linux-audio-user] Re: [ANN] Radium v0.63

Mark Knecht: > > http://www.notam02.no/radium/ > > > Kjetil, > Hi. Radium looks interesting, but I'm not sure I understand it from > just a quick look at screen shots. Is it along the lines of a tracker? Its a bit like a tracker, yes. But without a lot of the limitations found in trackers. It takes the best from the tracker, which is fast editing with lots of information using small space; less time used for navigating. The screenshot is a bit outdated though, in >v0.60 you can have a total graphical layout looking more like a vertical pianoroll as an alternative. There is also a new track showing the tempo graphical with gradiently changing colors. > Time seems to be progressing downward. Yes. > What is placed in each column? Its sort of explained here: http://www.notam02.no/radium/docs/radium_Sections/visibleoverview.HTML > Wave files? Loops? Unfortunately just midi data for now. The code is modular build up, though, so its not ~that hard to add sample-support. > I'm guessing the numbers in the left column (headed > with the number 15) indicate how long you play a loop at a given > vertical slot? The track to the right for the track headed with the number 15 shows the sublevel, and the track headed with the number 15 shows the linenumber in the level showed in the sublevel track. Its a flexible way to zoom, and has nothing to do with looping. The number "15" shows the linenumber at sublevel 0. sublevel 0 is colored black sublevel 1 is colored white sublevel 2 is colored brown etc.. Its not that confusing when you actually use it yourself, and you don't have to use it if you don't want to. There are two ways to zoom, the one I have been talking about now, which I have called local zooming, and the other way which is global zooming. The global zooming is just a plain graphical effect. You do a local zoom by pressing left shift+<arrow down/up> and global zooming by pressing left meta+, and left meta+. and left meta+. > Does the relative tempo column effect the pitch of the > files being played? > > Anyway, it looks interesting. > Thanks. :) --
