Version 1.2: room acoustics in detail, and the app is now free. NEW • Reverberation by frequency: RT60 per octave band (125 Hz to 4 kHz), with your target and tips for the bass. • Material absorption: absorption coefficient curves for every surface in the room. • Noise map: measure the level at several spots and get a heat map of the noisy zones. • Double wall: mass-spring-mass calculator with resonance frequency and insulation by frequency (mineral wool, decoupled leaves). • The new charts also appear in the measurements table and the PDF report. • Number fields now accept the decimal comma. THE APP IS NOW FREE • Free: sound meter, analyzer, measurements table and PDF export. • Treatment and Calculators unlock with a one-time purchase, no subscription. • If you already bought the app, everything stays unlocked automatically.

About
Measure, analyze and treat sound like a pro: from a quick noise check to a full room-acoustics study. FREE • SOUND METER: live dB level with min, average and max, microphone calibration against a reference meter, and color-coded history charts. • ANALYZER: frequency spectrum, with pure-tone detection (frequency, period and wavelength). • MEASUREMENTS TABLE: a log of everything you measure, with filter, sort and a clean PDF report with charts. COMPLETE (one-time purchase, no subscription) • TREATMENT: enter your room (or scan it with LiDAR), pick the materials, and get the reverberation time (RT60) against a target for your use case, plus how much acoustic foam you need. • RT60 BY FREQUENCY: octave bands from 125 Hz to 4 kHz, so you can see where the bass is the problem. • MATERIAL ABSORPTION: absorption coefficient curves for every surface of the room. • NOISE MAP: tap points on the room plan, measure the level at each one and get a heat map of the noisy zones. • LIVE RT60 MEASUREMENT: a short noise burst, and the microphone measures the decay. • CALCULATORS: sum of sound sources, sound pressure level, frequency, period and wavelength, and a double-wall (mass-spring-mass) calculator with resonance frequency and insulation by frequency. Available in English and French. Your measurements stay on your device. No account, no ads. If you bought Acoustic Detector before it became free, everything stays unlocked automatically. Results are indicative: they rely on standard acoustics models and the iPhone microphone, not on certified instruments.
