Real-time SPL
Continuous A-weighted level at 10 Hz, exponentially smoothed for a stable, readable display. The same measurement chain feeds the dose counter, the calibration tools, the Leq statistics, and the Lyra integration — one number, multiple jobs.
Live menu bar readout
Show a live SPL number right in the menu bar — dBA, dBC, or alongside the dose icon — for an at-a-glance reading without opening the popover. Optional one-decimal precision and color-coded thresholds (green / yellow / orange / red, defaults from the NIOSH risk gradient at 70 / 80 / 95 dB, fully configurable). Pick the variant that suits how you work in Settings → Menu Bar.
Pinnable measurement panel
Detach the measurement display as a floating window that stays above your DAW. Pick which sections to keep — hearing dose, current SPL, monitoring discipline, Leq / Ln, active session, today's summary — in Settings → Panel. The window auto-resizes as you toggle sections, remembers its position, and uses the new Liquid Glass material on macOS Tahoe (26+). Click the menu bar pin again — or double-click the panel — to dismiss.
Target-level calibration
A pink-noise wizard pins your monitor controller to a specific dBA target (79 dBA approximates Katz's K-System reference; 81 lands close to cinema reference). Captured calibrations record the knob-position note, target value, and measured SPL, with a stale-calibration hint after 90 days. One record per output device, so monitors and headphones are calibrated independently.
Monitoring Discipline
Tracks how consistently you actually monitor at your chosen reference. Pick an industry preset (73 / 79 / 83 / 85 dBA) or set a custom target with a tolerance band, and the menu bar shows a live on-target % chip with a green / yellow / orange ladder, a three-segment under / on / over bar, and a drift hint. Today's Summary aggregates the same metric across sessions; per-session figures land in History alongside the dose stats. Useful at any SPL — fills the gap left by NIOSH dose, which stays at 0 % below 80 dBA.
Monitoring alerts
Opt-in notifications when your level drifts (rolling 30-min Leq vs session baseline) or sustains a deviation off target. Each category has its own 30-min snooze, so silencing a drift alert doesn't muffle a dose alert.
Lyra integration
After a target-level calibration, hand the position straight to Lyra with a single click. Pick a slot (1, 2, or 3), confirm the name, and your calibrated listening level is one keystroke away from any app — Ctrl+F10 / F11 / F12 in Lyra. The slot remembers the dB SPL value and shows it as e.g. "Mix — 79 dB SPL" in Lyra's menu and HUD.
Hearing dose
Accumulates your daily exposure using the NIOSH formula. Four colour-coded states — Safe, Caution, Warning, Over-exposed — update in the menu bar icon in real time. Resets at midnight. Persists across restarts.
Leq & Ln stats
Rolling energy-average level (Leq) over 1-, 10-, and 30-minute windows shows how loud you have actually been — not just right now. L10, L50, and L90 percentiles reveal the character of a session: L10 captures your loud peaks, L50 your typical working level, L90 the background noise floor. Useful for both dose context and verifying you're holding a calibrated reference band.
Mic frequency correction
Compensates for your measurement microphone's frequency response so the SPL reading reflects the room, not the capsule. A pink-noise sweep measures your mic's deviation from flat and applies the inverse correction before A-weighting. Per-mic profiles can be saved and recalled from Settings.
Peak monitoring
C-weighted peak impulse tracking per EU Directive 2003/10/EC. Notifies you when levels cross the 135, 137, or 140 dBC action values. Per-session and daily peak counts recorded.
Session tracking
Auto-detects when you open a DAW and starts a session. 15 DAWs supported out of the box — Luna, Logic, Pro Tools, Ableton, REAPER, and more. Manual start and end also available.
Session history
Full 30-day history with per-session dose contribution, average and peak SPL, and peak impulse counts. Seven-day bar chart shows your weekly EU L_EX,w exposure level at a glance.
History window
Dedicated calendar window for exploring any date range in your 30-day archive. Select a range on the calendar to see cumulative dose, daily average, EU weekly level (L_EX,w), peak dBA, peak dBC, and impulse counts — all in one view. Each stat includes an explanation popover with thresholds and regulatory context.
Instantaneous peaks
Tracks A-weighted instantaneous peaks above 115 dBA — the EU Directive 2003/10/EC ceiling for any single moment of exposure. Counts per session, separate from the C-weighted impulse limits.
Conservative mode
Optional setting that uses max(dBA, dBC) for dose accumulation. Designed for bass-heavy work — sub-mixing, kick drum tracking, live sound — where A-weighting alone may underreport physical energy. No formal standard; a maximum-protection option you can enable in Settings.
Input channel selection
Pick any individual input channel from your audio interface — not just the default stereo pair. Useful for measuring via a talkback mic, a dedicated measurement input, or any other channel on multi-channel interfaces like the Apollo Twin X. Channel names are read directly from the driver.
Non-invasive
Lives in the menu bar with no Dock icon. Measures passively via any CoreAudio input device — a built-in mic, a measurement mic, or any interface input channel. Nothing touches your signal chain.
Auto-updates
Stays current automatically. You'll be notified in the menu when a new version is available.
Launch at login
Optionally start with macOS so dose tracking begins as soon as your session does.
