How do I simulate a speaker?

Open this page and use the live Additive Synthesis tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive a speaker from your own measurements.

Harmonics

Any periodic waveform is a sum of sine harmonics — the basis of additive synthesis. A sawtooth needs every harmonic falling as 1/k; a square only odd harmonics; a triangle odd harmonics falling as 1/k². Add more harmonics to sharpen the shape, and watch the Gibbs overshoot ripple at the edges.

Governing equation

x (t) = k = 1 \sum 8 a_{k} sin (2 π k f t), a_{k} = \frac{1}{k}

Reading this result: The sawtooth needs every harmonic falling as 1/k; 8 of them sharpen the ramp but leave a Gibbs ripple at the jump.

About this simulation

The full Additive Synthesis tool models a speaker with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
