🔬 Side Quest / Depth Level 7
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?
