Window Functions for a Class-D amp
Simulate a Class-D amp live in your browser. This runs the real Window Functions solver — adjust the inputs, watch it respond instantly, and export the result. No install, no account.
Controls
Chopping a signal into a finite chunk smears its spectrum — spectral leakage. Tapering the chunk with a window (Hann, Hamming, Blackman) trades a wider main lobe for much lower side lobes, cleaning up the spectrum. Educational tool.

About this simulation
The full Window Functions tool models a Class-D amp 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.

Frequently asked questions
- How do I simulate a Class-D amp?
- Open this page and use the live Window Functions tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.
- Is it free?
- 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 Class-D amp from your own measurements.
