Hit Connect Your Sessions & Devices above on any laptop at the mix position. One click creates your session and a QR code per zone — Balcony, Lobby, Stage, anywhere.
Helpers install 1dB Live, open Profile → 1dB Live, and scan the zone QR. A green LIVE banner on the phone confirms it's streaming. Then they just… set the phone down in the zone.
Every zone updates every second — level, LEQ, peak, trend. Set an SPL alert, reset all zones at the top of a song, make a phone beep to find it, even record reports remotely.
Phone mics are fine for trends — for calibrated absolute SPL, plug in the ~$40 iMM-6C calibrated measurement mic. 1dB Live imports its per-serial calibration file: exact sensitivity and a flattened frequency response, automatically applied whenever the mic is connected. The dashboard even shows each zone's calibration status, so you know which numbers to trust. Find it on Amazon →
A/C/Z weighting, FAST/SLOW, LEQ windows, L10/L50/L90, SEL, LCpeak, dose (NIOSH/OSHA/EU), hold & max markers.
1/3-octave real-time analyzer (8192-pt FFT), scrolling spectrogram, live history.
RT60 reverb time and averaged room response — tune the room with the same phone that monitors it.
Timed surveys, session logging, branded PDF + CSV export with venue & notes.
10-instrument tuner with strobe and pitch-stability trace, sample-accurate metronome with tap tempo.
Reset stats, locate phones, start/stop remote recordings — from the dashboard, ~1 second latency.
Drag each zone onto a plan of the room and read the whole venue by colour — no numbers required.
Scrub back through the session and see how every zone tracked against each other over the night.
Hand out a read-only board at 1db.live/s/CODE — production, the promoter, or a noise officer can watch without installing anything.
Set a ceiling per zone and get warned as it's trending toward the limit, not after you've blown through it.
Phones on the same Wi-Fi stream straight to the desk over the local network, and fall back to the cloud path when they're not.
Any mix of devices in one session — and an iPad at front of house is a full meter and a desk.
