Connecting audio (and now MIDI !)...
from any OS X application,
to any OS X application
...and it's free!
Version 0.9 now available!
What's Jack?
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 Starting in version 0.88, it also routes MIDI to/from any OS X application.
Jack is different from other audio server efforts in that it has been designed from the ground up to be suitable for professional audio work. This means that it focuses on two key areas: synchronous execution of all clients, and low latency operation.
What's Jack OS X?
Jack OS X is an OS X implementation of Jack, and it installs everything necessary to take full advantage of Jack on OS X. This includes:
The Jack server
The infrastructure you need in place to use Jack
The JackRouter
The JackRouter is a CoreAudio “user space” driver that allows any OS X CoreAudio application to become a Jack client.
The Jack audio plugins
Both AU and VST “Jack-aware” audio plugins are provided, which can further expand the limitless audio routing possibilities when using Jack.
The JackPilot application
JackPilot offers an easy to use GUI interface that allows you to control the Jack server, and manage the audio connections between applications and/or plugins.
