fftFlipBook

A flip book to explore the FFTs of audio visually.

Use

Install Dependencies:

• npm install --save react react-dom

Then install library:

• npm install --save react-fft-flipbook

assuming this is an index.js in src/

import React from 'react'
import ReactDOM from 'react-dom'
import ReactFftFlipbook from 'react-fft-flipbook'

import "../node_modules/react-fft-flipbook/dist/package/styles.css"

ReactDOM.render(
    <ReactFftFlipbook
        width={400}
        height={400}
    />,
    document.getElementById('app')
)

DEVELOP

Run

npm run start

The Dream

• capability of stopping the soundfile at any point and getting the 'frozen in time' but not stuttering buffer. It requires a level a DSP I don't understand. Or maybe it's impossible. Perhaps it could be imitated with AI. "Loop" becomes "Freeze"

The MVP

• can play audio... start, loop, stop
• produces fft image with what is currently in buffer
• dropzone...
• UI looks decent
• confirm that you can plug this in another app as a package

The Nice features to have

• stereo (process both channels, but an easier idea would be to simply mix them down first as an MVP)
• a way to keep previous files in the queue... If you uploaded a file and it has already processed, why not keep a few of the last ones in memory?. You can make an object that can represent 'this done', 'that done' and it can be a todo list
• re-enable tests...? Why is it so hard for testing libraries to be okay with classes that have anything other than static methods in them...
• compress the spectrum and use colors to differentiate the magnitude?
• better logic as far as incrementing / decrementing / playing past index safety
• better positioning of the units
• drastically better UI
• different builds for importing as not only a package but <script> tag
