I am not aware of an application that does this. What do you need this for?

ALSA device/resource busy when using alsa-jack plugin

by James Morris

Hi, I want to record some sound from arnold (a CPC emulator) which has ALSA output. Unfortunately when using the alsa-jack plugin, arnold says: Playback open error: Device or resource busy So I then tried the "Jack and Loopback device as Alsa-to-Jack bridge" as referenced in the JACK FAQ but still the same busy message. Does anyone know why the asoundrc trickery does not work for this application and if anything can be done? Arnold has not been developed since 2009 so I'm wondering if it is using a deprecated way of using ALSA? Cheers, James.

[ANN] Qtractor 0.5.3 - The Delta Whisky natural cask strength!

by Rui Nuno Capela

TYOQA is officially over. Qtractor 0.5.3 (delta whisky) drops from angels share! nuff said :) Impromptu release highlights: * Clip drag-and-move stepping with keyboard arrow-keys (FIX) * Plugin parameter automation GUI feedback (FIX) * LV2 plugin Qt4 GUI support (FIX) * Clip/Split on current play-head location (FIX) Slaintheva! Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: - source tarball: http://downloads.sourceforge.net/qtractor/qtractor-0.5.3.tar.gz - source package (openSUSE 12.1): http://downloads.sourceforge.net/qtractor/qtractor-0.5.3-2.rncbc.suse121.sr… - binary packages (openSUSE 12.1): http://downloads.sourceforge.net/qtractor/qtractor-0.5.3-2.rncbc.suse121.i5… http://downloads.sourceforge.net/qtractor/qtractor-0.5.3-2.rncbc.suse121.x8… - once upon the time, eons ago: user manual: http://downloads.sourceforge.net/qtractor/qtractor-0.3.0-user-manual.pdf Weblog (upstream support): http://www.rncbc.org License: Qtractor is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Change-log: - Fixed initial LV2 plugin UI widget/window titles. - Attempt to get any brand new LV2 plugins Qt4 enabled UI's working on either slv2 and lilv build modes ;) (nailed by falkTX, thanks). - Current clip is ultimately inferred from the one under the play-head position and current selected track; the last one clicked over and/or selected still has precedence (following request by Loiugi Verona). - Drag-moving clips horizontally with the keyboard arrow-keys just got a step better with a fixed minimum of one pixel, depending still on the current snap-per-beat setting and horizontal zoom level (as suggested by Louigi Verona, thanks). - Get maximum and minimum peak values back when drawing audio waveforms.- Automation play/feedback has been missed to show on those plugins that provide their own GUI, now on par with all the rest 'homebrew' widgets (eg. generic plugin properties dialog). - All plugin parameters automation and selection were left inaccessible until the generic native plugin dialog is eventually shown, now fixed (re. bug #3463916). Enjoy && Happy New Year! -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

Qt apps are fine with (KDE ;) but even with) GNOME. No Linux audio user seriously will use GNOME3 or Unity. IMO Linux audio has become pro-audio, but nowadays the surroundings, such as a DE, become unusable for pro-audio. Keep in mind that the first "law" of pro-audio is to be work flow compatible, in an idiot proof kind. Every professional audio engineer will be able to use any app, from any OS, at any studio. Exotic, fashion DEs, abstruse session handling etc. are grotesque, non-pro-audio. :( Ralf

I also don't like to be forced to use a proprietary Nvidia driver, but GNOME3 does, hence I'll have to offend licences to use the rt patch. Cheers! Ralf

rtmp server

by Raffaele Morelli

hi, I am using shoutcast for streaming and would like to setup a simple player on a web page, eg. http://www.radiocittaperta.it/live/radio.html Shoutcast stream is AAC so googling around I discovered that an RTMP server is needed between the AAC stream and the flash-based players. so, is there anybody using an rtmp server like crtmp? regards -r -- *L'unica speranza di catarsi, ammesso che ne esista una, resta affidata all'istinto di ribellione, alla rivolta non isterilita in progetti, alla protesta violenta e viscerale.*

Some christmas music

by Julien Claassen

Hello everyone! It shouldn't be said, that I'm a spoil sport or kill joy - although I might be :-). Still I thought I'd throw in my penny for the christmas mood. Three Bach chorales played on Aeolus: http://juliencoder.de/nama/exporting_xmas.ogg or (for the poor ogg-deficient): http://juliencoder.de/nama/exporting_xmas.mp3 Or of course from the website: http://juliencoder.de/nama/music.html The chorales are "Herzlich tut mich verlangen" (Weihnachtsoratorium - christmas oratorio), "O Haupt voll Blut und Wunden" (Matthauespassion - St. Matthew's passion) and "Wir Christenleut" (Weihnachtsoratorium again). I know, that the St. Matthew's passion is for easter, but its the same melody as the first one, only with a completely different harmonisation and the keys worked nicely for me, for I didn't want to move from a minor to f# minor in one go. :-) I bag to excuse the two obvious glitches in there, but it was late night and when it comes to christmas I'm a kill joy after all and why I should I bring more fun to this time of year? :-) I still hope yo like it and with that say merry christmas or whatever merry time you'd like to celebrate!
