JackBridge (former "JackRouter")

About

This is an alternative to jackrouter for MacOS. JackBridge acts as a virtual audio interface (currently 2in-4out) connected to Jackaudio server directly. Even though the master clock of JackBridge becomes synchronized with Jack server, Core Audio Applications connected via JackBridge is out of jackaudio connection graph scope. Therefore, I changed the name from "Router" to "Bridge".

NOTE: This is still experimental prototype implementation. Please be careful using it.

Changes

  • Master clock synchronization with Jack server

Limitation

  • Supports only 44.1/48kHz mode.

Build

Checkout the codes in "JackBridge" branch.

git checkout JackBridge

JackBridge consists of two parts, a daemon and a user-space Core Audio driver.

  • JackBridge daemon

    You can build two versions of daemon.

    JackBridge: bridge only audio (RtMidi library not required) JackBridgeWithMidi: bridge audio and MIDI (RtMidi library required)

    rtmidi libraries are required to build JackBridgeWithMidi. Please install before build. To build the JackBridge, just run 'build.sh' under the directory.

cd daemon
./build.sh

  • JackBridge driver

    Build the project named "JackBridgePlugIn.xcodeproj" with Xcode.

Installation

  • JackBridge daemon

    Locate wherever you like. Just execute after jackd.

  • JackBridgePlugIn driver

    Copy all contents to '/Library/Audio/Plug-Ins/HAL' and restart coreaudiod.

sudo cp -r JackBridgePlugIn.driver /Library/Audio/Plug-Ins/HAL
sudo -u _coreaudiod killall coreaudiod

Then you can see JackBridge device on your application. And you can also change configuration with Audio MIDI setup application.

TODO

  • Multi instance support
