LUFS meter for Ableton Live built for clear loudness monitoring during mixing and mastering.
Master Meter is a LUFS meter for Ableton Live that helps you monitor loudness clearly and make faster level decisions while mixing and mastering.
Master Meter is a free Max for Live loudness metering plugin for Ableton Live. Built on the ITU-R BS.1770 standard, it gives you broadcast-grade metering — Momentary, Short-term, and Integrated LUFS, True Peak, LRA, RMS, and a real-time waveform — all with zero latency.
Full ITU-R BS.1770-5 compliance. V2 True Peak uses 4× oversampling with a 48-tap FIR interpolation filter — the same algorithm used in professional broadcast loudness meters.
Pure monitoring — no processing, no latency. Your audio passes through completely untouched. Drop it on your Master track and forget about it.
No trials, no feature gates, no upsells. Full-featured loudness metering for every Ableton Live producer. Download and use it — that's it.
Know your real peak level.
not just sample peaks, but the actual signal peaks between samples.
Essential for avoiding clipping on D/A conversion and codec encoding.
How dynamic is your mix?
LRA tells you the difference between the quietest and loudest moments.
crucial for genre-appropriate dynamics.
Classic root-mean-square metering.
While LUFS has become the modern standard, RMS remains a familiar reference for many producers.
Especially useful for comparing perceived loudness during mixing.
A live stereo waveform display shows the audio signal in real time.
