WaveScope

WaveScope is a beautifully simple visualizer for two kinds of waves you live inside every day: the sound you can hear and the electromagnetic spectrum that includes visible light.

Pick a scope. Watch it move.

SOUND SCOPE
The audible range (20 Hz – 20 kHz) is split into seven color-coded bands:
• Sub-bass • Bass • Low mid • Midrange • Upper mid • Presence • Brilliance

Each band animates as a sine wave whose density grows with frequency, so deep sounds roll slowly and highs ripple tight and fast — a single glance tells you where the energy lives.

Switch on Live Mic and WaveScope taps your microphone, runs a real-time FFT (Fast Fourier Transform) on the incoming audio, and drives each band's amplitude from what it hears. Hum for sub-bass. Snap fingers for the brilliance band. Play music and watch the whole spectrum dance.

LIGHT SCOPE
The full electromagnetic spectrum, from radio waves to gamma rays, laid out on one scope. The visible slice — Red, Orange, Yellow, Green, Cyan, Blue, Violet — sits in the middle, with infrared and ultraviolet flanking it, and the high-energy/low-energy extremes drawn in representative tints.

Bands a consumer device cannot actually measure (radio, microwave, IR, UV, X-ray, gamma) are marked with a sensor-off icon — honest about what's measurement and what's illustration. Live Ambient mode runs a simulated daylight model that tracks the time of day, tilting warm at sunrise and sunset, cooler at midday.

WHY YOU'LL LIKE IT
• Built natively for Apple Vision Pro using SwiftUI and RealityKit
• Real microphone analysis with Accelerate-powered FFT — no fakery on the audio side
• Honest labeling: nothing pretends to be a measurement it isn't
• Built-in Help screen with band tables, frequency ranges, and wavelength data
• No ads, no tracking, no accounts, no network — everything runs on-device

Whether you're a musician curious about where your mix is sitting, a teacher demonstrating the spectrum, or simply someone who finds waves mesmerizing — WaveScope makes the invisible visible.
