See sound in real time — a live spectrogram and frequency analyser that turns your mic into a precision audio instrument. Prism Audio turns your iPhone or iPad microphone into a real-time spectrogram and frequency analyser — a precise, beautiful window into the sound around you. Watch a smooth scrolling waterfall paint every frequency as it happens, read the dominant pitch and nearest musical note instantly, and track levels on a responsive dBFS meter. Whether you're tuning an instrument, hunting a noise, studying acoustics, or just curious what sound looks like, Prism Audio makes it visible. FEATURES • Live scrolling spectrogram with linear or logarithmic frequency axis • Real-time dominant frequency (Hz) and musical-note readout • Tap-and-drag crosshair to inspect any frequency • Responsive level meter with peak hold • Guided presets for full-range, voice, music and more • Choice of colour maps and adjustable brightness • Dark, distraction-free instrument design PRISM AUDIO PRO (one-time purchase) • Remove all banner ads • Record sessions and export PNG images or audio • High-resolution 4096 and 8192-point FFT for sharper detail • Freeze the live view to inspect and pan the timeline • Share clean spectrogram images without a watermark PRIVACY The microphone is used only while the live display is on screen. Nothing is recorded, stored, or sent anywhere unless you explicitly export it. Note: Prism Audio shows a relative dBFS reading, not a calibrated SPL measurement.
