## What is Prism Audio?

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.
