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 • Spectrogram sensitivity control to bring out quiet detail 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) • 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. Informational only, no warranty. Measurements and conversions are estimates — verify anything critical with calibrated instruments.
