LUFSBar Pro measures system audio loudness without virtual routing devices. This macOS app hosts five Audio Unit inserts via Core Audio taps while displaying EBU R128 and ITU-R BS.1770 readings directly in the notch or floating window.
Metering reflects post-chain output, showing M/S/I LUFS and True Peak values against streaming platform targets. Users compare measurements to saved references while narrowing analysis to specific applications or output devices during active playback sessions.
Output device switching works mid-playback without touching DAW engine settings or reopening projects. Libebur128 handles all computation natively on Apple Silicon and Intel machines running macOS 14.4 or later with proper notarization.
Twelve dollars covers five Macs with a full-feature 14-day trial available for testing. A free MIT-licensed version retains identical metering capabilities but removes insert hosting for users needing measurement-only functionality without processing chains.
