Kiss FFT in WebAssembly

Install

$ npm install kissfft-wasm

Note that you may want to copy the kissfft.wasm file explicitly during building process since most compilers/bundlers won't handle it by default.

Usage

• Use APIs such as fft, ifft, etc. (See API)
• For Complex input, note that (input[2i], input[2i+1]) are the real and imaginary part of the i+1-th number, respectively.
• For Real input, use rfft, irfft, etc.
• If using lower functions, remember to free every class you created after its usage.

Examples can be found in examples folder.
