Re: [linux-audio-dev] Anyone planned a GTK2-based Multitracker?

Use a desent high-level non-crippled language like lisp, python or ruby. The lowlevel stuff must of course be written in c/c++ or something, but only a very small amount of multitracker-code is that low-level. Yes, I have made _huge_ programs in C myself, but that was only because I was so damned inexperienced and had so damned slow machine to work on at the time. Today, where there are so many descent libraries for lisp/python/ruby/ada(?)/etc(?), and the machines are so fast, as good as no one should use c++ for high-level things. You'll waste time. Yes, this might start a flame-war, but I really think people should be aware of the C/C++-stupidness. --

I said; use a high-level language for high-level operations. I'm not saying: Do computer-intensive/realtime critical operations with lisp/python/ruby/etc. Ardour consist of about 90% GUI code, if I have understood correctly. Those 90% of code could have been written in a more high-level language with garbage collectors, proper list-functions, dynamic typing and other helpful things c++ does not provide because C++ is supposed to be extremely fast, allways. Or in case not, why not? --

[linux-audio-dev] linuxjournal.com article on upcoming linux audio conference

by Joern Nettingsmeier

hi everyone ! it seems our friend dave has been very active again. in case you haven't seen it yet, here is a nice teaser for the 2nd linux audio conference in karlsruhe at the end of april: http://www.linuxjournal.com//article.php?sid=7514 best, jörn -- The handles of a craftsman's tools bespeak an absolute simplicity, the plainest forms affording the greatest range of possibilities for the user's hand. That which is overdesigned, too highly specific, anticipates outcome; the anticipation of outcome guarantees, if not failure, the absence of grace. - William Gibson, "All Tomorrow's Parties" Jörn Nettingsmeier Kurfürstenstr 49, 45138 Essen, Germany http://spunk.dnsalias.org (my server) http://www.linuxaudiodev.org (Linux Audio Developers)

[linux-audio-dev] ladspa: delayorama

by Tim Blechmann

hi steve and list... i've experiencing some problems with the delayorama plugin ... if the (feedback * taps) is bigger than 100, there is a big possibility of clipping / sound getting louder and lounder / the plugin getting unstable (???)... i'd suggest to post a warning to stdout or stderr that the plugin will get unstable when using these values ... cheers...

[linux-audio-dev] ladspa: flanger

by Tim Blechmann

hi steve and list again ... there is another problem with the ladspa plugin flanger, that's quite annoying ... if i change the lfo frequency, there is a good chance of the plugin to become unstable ... i suppose it's a denormal problem, but i'm not sure ... does anyone have a hint, what the problem might be, how to solve it? cheers...

[linux-audio-dev] LA Conference#2 Programme PDF now online

by Frank NEUMANN

Hi all, just a little update on what's going on with the upcoming Linux Audio Conference in Karlsruhe on April 29th - May 2nd: The programme is now available as a PDF, too - just visit http://www.zkm.de/lad and click on the PDF link. While this is not necessarily the absolutely final version of the programme, there should not be big changes anymore from now on. We have one additional highlight with a presentation by someone from Hartmann showing the Neuron (which also uses LinuxInside :-), and in general I'm really quite excited now about the whole event. I hope you'll like it, too. The PDF is also ideal to give out at local Linux users group meetings etc to do some advertising there - we welcome that! Greetings, (and hope to see some of you soon), Frank

[linux-audio-dev] [Tech-OT] Succeeding in following-up...

by Mr.Freeze

Hi, I definitely cannot keep a good tree on the threads I start (take a look at "PdDSP?" and you'll see what I mean)... I've tried most combinations of those '[mailing-list]', 'Re:' and 'Place-your-title-here' strings unsuccessfully. What's the best way to achieve good results, provided I suscribed for a daily batched message list, and therefore cannot answer directly to the original messages? Hoping you'll not throw me away to the creeping forum world, Christian Frisson
