Install

npm install bitdepth

Use

Currently there is no dithering when changing the bit depth.

• 16-bit is always int
• 32-bit can be int or float
• 64-bit is always float.

const bitDepth = require("bitdepth");

// 8 bit samples
let samples = [0, 255]

// Make'em 32-bit floating point
bitDepth.toBitDepth(samples, "8", "32f");

console.log(samples);
//[-1, 1]
