See the sound.

Every song you hear runs on physics, mathematics and engineering, not only musicianship. These small experiments let you explore that hidden side, from Fourier series to room acoustics. Each runs in your browser, and the formulas are one click away.

A space to explore, not our projects. Our research →

Signals

The maths that turns sound into numbers, and back.

01HarmonicsWhy different instruments sound different on the same note.Open
02Drawing with circlesThe power of the Fourier series: any closed shape, drawn by spinning circles.Open
03UncertaintyHeisenberg’s uncertainty principle, for sound.Open
04AliasingWhy a CD samples sound 44,100 times a second.Open

Sound

How sound behaves in intervals, instruments and rooms.

05Lissajous figuresWhy some intervals sound more pleasant than others.Open
06Chladni figuresSand shows where a vibrating plate stands still.Open
07Sound in a roomWhy every room sounds different.Open

Perception

What the brain adds to what the ear receives.

08The missing fundamentalRemove the lowest harmonic of a note, and you still hear its pitch.Open
09The Shepard toneA tone that rises forever and never gets any higher.Open

Make

Put it together and make some music.
