Install

npm install bitdepth

Use

Currently there is no dithering when changing the bit depth.

let bitDepth = require("../index.js");

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

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

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

toBitDepth()
