pretty-fast-fft

WebAssembly build of a small, pretty fast FFT library (PFFFT).

`npm i pretty-fast-fft` `pnpm add pretty-fast-fft` `yarn add pretty-fast-fft`

## Examples

# web

# view source

```ts import { createRunner } from 'pretty-fast-fft' const blockSize = 4096 const stepSize = 1024 const main = async () => { const runner = await createRunner(blockSize, stepSize) const buffer = await (await fetch('./test/fixtures/sound.ogg')).arrayBuffer() const ctx = new OfflineAudioContext(1, 1, 44100) const audioBuffer = await ctx.decodeAudioData(buffer) const floats = audioBuffer.getChannelData(0) const stft_magnitudes = runner.processAudio(floats) console.log(stft_magnitudes) } main() ```

This is simply npm packaging for this project: > https://github.com/JorenSix/pffft.wasm ## API
