The Frequency Doubler

Operator, the math of the Octave is simple: 2x Frequency. Use the oscillator to verify this law of physics.

The Rule of Two

Every time you go up one octave, the frequency doubles. Every time you go down, it halves.

1 : 2 Ratio

The Oscillator Lab

Drag the slider from A3 (220 Hz) to A4 (440 Hz). Watch specifically how the waves align.

RATIO: 1.00x

FREQ: 220 Hz (A3)

A3 A4

Verification Complete

Now that you've seen the physics, can you spot the Octaves by name?
