API Reference

⚡

GPU Acceleration

WebGPU compute shaders deliver up to 92x faster FFT calculations compared to CPU. Automatic fallback when WebGPU is unavailable.

📊

1D & 2D FFT

Support for 1D transforms (2-65,536 elements) and 2D transforms (up to 2048×2048 pixels) for image processing.

🎵

Audio Spectrum Analysis

Real-time frequency analysis with configurable FFT sizes and multiple window functions (Hann, Hamming, Blackman, etc.).

🔍

Frequency Domain Filtering

Low-pass, high-pass, and band-pass filters with ideal or Gaussian shapes for image and signal processing.

🔷

TypeScript First

Full type definitions with strict mode support. Complete IDE autocomplete and type safety.

🚀

Zero Dependencies

No runtime dependencies. ~27 kB ESM bundle. Works in browsers and Node.js 18+.
