Live Audio Multi-Tool

Live Audio Multi-Tool (LAM-T) is a fast, offline toolbox for live sound engineers, system techs, AV installers, and musicians. Everything you reach for at a gig — an analyzer, an SPL meter, a delay calculator, sub-array alignment, a signal generator — in one clean app. No account, no ads, no tracking.

REAL-TIME ANALYZER (RTA)

• Fractional-octave RTA with a live peak readout

• A / C / Z weighting

• Spectrogram view, freeze, peak hold, and capture/compare

• Adjustable Y-offset for quick reference matching

SPL METER + Leq

• dB(A), dB(C), dB(Z) with peak hold

• Running Leq over 1, 15, or 60 minutes

• Per-device calibration offset — match it to a real meter once and it sticks

DELAY CALCULATOR

• Speed-of-sound delay from real temperature and humidity (auto-filled from your location)

• Connect a Bluetooth laser rangefinder to drop a measured distance straight in — verified with the Bosch GLM 165-27C (GLM 120 C family); Leica DISTO (and Stabila LD), older Bosch GLM, Stanley TLM99s / DeWalt DW099S and older Mileseey on a best-effort basis; any other meter can send a one-tap diagnostic report so support can be added

• Feet or metres

SUB-ARRAY DESIGNER

• Broadside and end-fire arrays

• Cardioid tops (castellated or all-subs)

• Per-sub delay times computed for your spacing and coverage

SIGNAL GENERATOR

• Sine (20 Hz–20 kHz, log sweep), pink noise, and a polarity-check pulse

• Polarity reader — check a speaker's polarity through the mic

UNIT CONVERTERS

• Temperature, distance, and pressure

• Reads your device's barometer for true local air pressure

Built for the real world: it works offline, launches instantly, and stays out of your way.
