1dB Live

Turn any phone into a calibrated sound meter — then run a whole venue from one iPad. Live spectrum, zone limits, predictive alerts, and one-tap compliance reports.

1dB Live turns your phone into a precision sound-level meter — and your tablet into a live monitoring desk for an entire venue.

Whether you're a front-of-house engineer, a house-of-worship volunteer, a DJ, or a facility manager, 1dB gives you professional acoustic measurement and real-time multi-zone monitoring in one beautiful app.

MEASURE LIKE A PRO • Real-time SPL in dBA, dBC, or dBZ with Fast/Slow time weighting • LAeq, peak, min/max/avg, and statistical levels (L10/L50/L90) • Live 1/3-octave RTA spectrum and spectrogram • Noise dose (NIOSH/OSHA/EU), SEL, crest factor, dominant frequency • Calibrate against a reference meter for accurate readings • Works completely offline

RUN THE WHOLE ROOM — 1dB LIVE • Turn one tablet into a desk; phones join by scanning a QR code • See every zone's level, spectrum, and stats on one screen • Local Wi-Fi for real-time streaming, with automatic internet fallback • Wall-display Dashboard mode for front of house

ZONES & FLOOR PLANS • Draw zones with dB targets on a floor plan of your space • Drop each device's pin into a zone to assign it • Multiple floor plans for multi-room venues • Green / amber / red roll-up so anyone can watch the room

STAY IN THE SAFE ZONE • Predictive "approaching the limit" alerts before you cross a cap • On-device feedback (ringing) detection • Push notifications so you're warned even when you look away

PROVE IT • One-tap session compliance reports (PDF & CSV) • Per-device LAeq, peak, and time-over-limit • Ideal for permits, workplace noise records, and venue documentation

WATCH FROM ANYWHERE • Share a read-only web link so anyone can watch the board in a browser • Or turn a spare tablet into a second-screen dashboard
