Audio server

Jack (the Jack Audio Connection Kit) is a low-latency audio server, written originally for the GNU/Linux operating system, and now with Mac OS X support. It can connect any number of different applications to a single hardware audio device; it also allows applications to send and receive audio to and from each other.

  • Fixed Jack Audio Router to work with Final Cut Pro

  • Fixed Jack Audio Router to allow working with both Jack AU and Jack VST plugins at the same time

  • Added "blacklist" functionality to Jack Audio Router, allowing for some clients to be rejected from being added. Currently, XQuartz (opened by

  • X11) is the only client on the list. This is mostly for the upcoming Ardour OS X port.
  • Fixed CoreAudio driver to fix a problem with multi-stream interfaces

  • New management of Jack plugin audio buffers (they are now allocated and managed in the JAR, not in the plugins), to address "dirty buffer" problem, especially in Logic.

  • Jack Audio Router (JAR) – 0.7.2

  • JackPilot – 1.5.4
  • JackOSX v 0.51 Oct 9, 2004 MacOS X PPC

The workaround restores the connection state of the application in question when the audio stream is resumed

    Sorry, but that connections manager interface just dosn't do it for me. why can't they just make a good gui? ...
    i find soundflower even if limited in patching possibilities much more clean and stable - personally.

    Jack Tools offer fantastic possibilities for connecting apps or work around I/O limitations of various apps with multichannel hardware. While there are still bugs making it sometimes necessary to relaunch the server and the connected apps a couple of times, once the apps are connected basically it works as expected. Obviously this is beta software, so it will surely improve over time.
    version 0.4, MacOS X PPC
    Great stuff!
    version 0.4, MacOS X PPC
    Il s'agit bien de rerouter virtuellement n'importe quel output stéréo d'application sonore de type "standalone" (Exemple: Max/MSP, Peak, Spark, iTunes, RealPlayer, Quicktime etc...) vers l'entrée de votre logiciel de composition préféré (Cubase SX, Logic, Digital Performer, Reason, Live...). Il y a même des plug-ins "aspirateur" (VST et AU) pour "capter" le son et le mixer via une piste VSTi.
    Fini les galères de rewire, plus besoin d'attendre les versions des plug-ins compatibles avec votre environnement. Le core audio d'OS X dans toute sa splendeur, exploité avec brio.
