Run Audio Unit Plugins on Your Mac’s System Output

MenuBUS – “The Master Bus for your Mac” – lets you run audio unit plugins on your Mac’s system output, straight from the menu bar.


menuBUS is a lightweight menu bar application that lets you capture your Mac’s system audio, host Audio Unit plugins in real-time, and pass the processed audio to an audio output of your choice.

Until now applying effects to the system audio has involved the use of multiple apps, audio drivers and aggregate devices, and in the case of paid apps that can solve this problem the user is still left with a lot of prep work and time spent managing app clutter.

MenuBUS Highlights

  • Full control of any Audio Unit plugin.
  • Works with any Audio Unit plugin that works in your DAW.
  • You can save your own presets. These can be switched with keyboard shortcuts.
  • Unlimited plugin slots, draggable via drag & drop.

menuBUS is still under development, but you can get early access by becoming a tester.

The app will cost $39 USD once it goes on sale in March 2017.

    Wow, this is great !!

  • I am a huge fan of Audio Hijack ($49) which is not a menu app, but can do what MenuBUS does on an application by application basis. Excellent tool. AU/VST. Seems like a lot of money for a single audio path…and AU only…

      So far I find it pretty buggy. Lots of crashes… But looks promising!

  • I downloaded and installed it. Setup worked well, I’d like to use it for room and headphone correction.
    Currently it does weird things to phase and the stereo image on my system.
    I use Audio Hijack as well which is my weapon of choice for this. Hopefully the developer of menuBUS can solve the problems.

    • Room correction is exactly why I use Audio Hijack (mostly). I have IK Multimedia ARC 2 installed and calibrated for the different sets of speakers/monitors. Changes the game completely

        Hi Chris,
        How do you use Audio Hijack with ARC 2? Are you able to run all of your Mac audio through ARC? I’m also trying Sonarworks Reference 3 now.

        • ARC 2 has an AU plugin which I use in Logic and friends. Same plugin can be inserted into the processing chain for an Audio Hijack session. I have a couple of different sessions, mostly iTunes and QuickTime player, and one that is “System Audio” -> ARC 2 -> iZotope Insight (meters) -> output device.

          Multiple, different hijacks can happen at the same time. I got ARC for a good price. Made a remarkable difference in my mixing and recording tasks. Bonus that it works with Audio Hijack.
