convert between images, audio and text

This tool allows you to convert between .png files, .wav files and .txt files, in any direction. It uses a Uint32Array as an intermediary data structure. You can use this library from the command line with synesthesia-cli.

Installation

npm install -g @ismay/synesthesia

Example

So for example, to convert an image to sound:

const fs = require('fs');
const { fromImage, toWav } = require('@ismay/synesthesia');

fromImage(fs.readFileSync('image.png'))
  .then(uint32 => toWav(uint32))
  .then(outputWavBuffer => {
    fs.writeFileSync('sounds.wav');
  });
