Web FFT benchmark

This page benchmarks many FFT implementations in your browser and plots the results in a graph. It assumes a modern browser that supports WASM SIMD. Only complex FFTs and power-of-2 sizes are compared for now. The benchmark (and implementations) are single core. All implementations are out of place and work with 32-bit floats. In consistency with FFTw's benchmark, the rates (in FFTs per μs) are multiplied by 5 N log₂(N) for normalization. You can find the source on GitHub; improvements or new (better) implementations welcome!
