Real-time audio for iPhone + iPad

See sound take shape.

Hilbert3D turns the sound around you into a luminous phase portrait, revealing pitch, motion, and harmonic character as they happen.

A DIFFERENT VIEW OF AUDIO

Not another waveform. A portrait of the signal.

Hilbert3D pairs the microphone signal with its Hilbert transform. Real and quadrature components become X and Y, drawing a closed, living path instead of a line moving through time.

A second transform adds color and energy. Stable tones form clean orbits; harmonics, breath, distortion, and noise reveal their own more intricate geometry.

PHOSPHOR WITH MEMORY

Watch the sound settle in.

A persistent Metal-rendered trace holds each movement just long enough to reveal it. Cycle-synchronous averaging steadies sustained pitches, while adaptive brightness and automatic gain keep the signal legible from a whisper to an instrument.

PITCH, IN CONTEXT

A tuner that shows more.

Read frequency, note, and cents while seeing timbre change around the same pitch.

MAKE A SOUND

01

Play

Explore guitar, strings, brass, woodwinds, synths, speakers, and effects.

02

Sing

Watch breath, vibrato, pitch, and resonance reshape the trace in real time.

03

Learn

Make phase, analytic signals, harmonics, and intonation visible and immediate.

PRIVATE BY DESIGN

Your sound stays yours.

Microphone audio is processed live on your device. Hilbert3D does not record it, save it, upload it, or send it anywhere.
