Interactive audio experiments and visualizations

Resonance

Interactive sound wave playground. Manipulate waveforms, frequencies, and harmonics in real time with intuitive controls and rich visual feedback.

Launch

Acoustic Field Simulation

Visualize pressure waves, vector fields, and Gaussian pulses. Toggle between wave visualization modes in a 2D acoustic simulation.

Canvas

Sound Spectrum Explorer

Explore how sounds are categorized across different spectra. Browse sound characteristics through an interactive taxonomy.

React

Sound Wave Types

Compare the frequency ranges other species use to make and hear sound. Tap any creature to hear a synthesized version — with anything outside human hearing pitched into it.

Audio

Beat Frequencies

Two pure tones, tuned almost together. Hear and see the wobble that appears when frequencies are nearly equal — one of the cleanest examples of math you can listen to.

Audio

Theremin

Pointer-driven sine: left/right is pitch, up/down is volume. Snap to a chromatic, major, minor, pentatonic, or Bohlen–Pierce scale.

Audio

Karplus–Strong Strings

Pluck a virtual string and hear the simplest physical-modeling synthesis there is: a noise burst sent round a feedback delay loop. Five tunings, brightness and sustain controls.

Audio

Vowel Formants

Drag through the IPA vowel chart and hear a buzzing sawtooth turn into recognisable vowels as two resonant peaks track tongue position and height.

Audio

Doppler

Drag the speaker around the listener. Wavefronts bunch up in front and stretch out behind, and the pitch you hear follows. Auto-orbit gives a clean siren-passing-by sweep.

Audio

Resonant Dashboard

An imagined student dashboard where every element — subject wheel, pods, coins, photo drop — reacts visually and sonically. Hover to colour the page, click for a chord, drop a photo for a chime.

Audio

Studio

Four-track loop sandbox. Bake drums / bass / pluck / pad patterns into tracks, or record from your microphone, then layer them. Live master scope and FFT.
