Lissajous Curve Interactive Demo

Lissajous curves are looping patterns formed by plotting two sine waves at right angles.

x=Asin⁡(at+δ) , y=Bsin⁡(bt)

This program lets you explore them interactively: adjust parameters, visualize musical intervals, and hear the frequency ratio.

🎵 Sound

Since Lissajous curves reflect the ratio between two sine waves, we can visualize musical intervals — which are two notes played together.

This demo lets you hear those intervals while seeing their shape. We use 220 Hz (A3) as the base frequency (a = 1). For example, a perfect fifth (3:2 ratio) plays A4 (440 Hz) and E5 (~660 Hz).

So yes, you can hear what Meta’s logo might sound like.
