The meter bar for Ableton Live.

MasterBar sits on top of Live's window and shows what your master is doing: loudness, true peak, spectrum and stereo image. It listens to Live directly, so there is no plugin to insert and no audio to route.

Download for Mac Free while in beta. Download it now and it stays free for you, also once there is a paid version.

Illustration. The real bar follows your Live theme and your own layout.

Built around Live

Glued to Live

The bar lines up with Live's window, takes on Live's theme, and comes and goes with Live. Want it apart? Pull it into its own window, full screen if you like.

Knows your arrangement

Your locators and bar numbers run along the loudness history. You see right away which section pushed the level, without scrolling back through the song.

Nothing to insert

No plugin on the master, no BlackHole, no aggregate device to build. Open Live and MasterBar is there. Close Live and it steps aside.

What it reads

Loudness: Momentary, short-term and integrated LUFS, loudness range and PSR
Peaks: True peak and sample peak, left and right
Target: Your own LUFS target, with how far you are from it
Views: Imager, spectrum, spectrogram, scope, loudness history, correlation
Accuracy: Checked against EBU Tech 3341 and 3342
Runs on: macOS 14.2 or later, Apple silicon and Intel, Ableton Live 12

Free while in beta

MasterBar is free to download and use. A paid version will follow later. Everyone who downloads it during the beta keeps it free, for good.

New versions install themselves. Leave your email if you also want to hear what changed and what is coming. That part is optional.
