A precision meter for loudness, true peak, dynamics, stereo image and tonal balance — with two views: Dive for a close look, Ascend for the at-a-glance verdict.
Arcoline reads everything once, then shows it at two densities — switch any time with Tab.
Every reading on one screen — for when you're diagnosing a problem or running a mastering QC pass.
One big loudness number and a ±LU delta against your target — the “am I safe?” answer, glanceable while you create.
Everything you'd otherwise open three meters to see — with built-in targets for Spotify, Apple Music, YouTube, broadcast and film. The manual covers every reading in full.
Momentary, Short-term and Integrated LUFS — the number platforms normalize to.
Inter-sample dBTP with a sticky over-flag, so a stray transient can't slip past.
Per-channel peak & RMS with peak-hold and clip detection.
PSR, PLR and loudness range — how squashed or open your master is.
Goniometer, phase correlation and L/R balance — a fast phase-safety check.
Low / mid / high energy split — catches a bass-heavy mix or a brittle top.
Free — a VST3 and AU plugin plus a standalone app, for macOS (universal, Intel & Apple Silicon) and Windows.
