Install

npm install bitdepth

Use

Supported bit depths (to and from):

• "8": 8-bit int (unsigned)
• Anything between "9" and "53" (integers, signed)
• "32f": 32-bit float
• "64": 64-bit float

const bitDepth = require("bitdepth");

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

// Make'em 32-bit floating point
// The input array is modified in place.
bitDepth.toBitDepth(samples, "8", "32f");

toBitDepth()

/**
 * Change the bit depth of the data in a array.
 * The input array is modified in-place.
 * @param {!Array<number>} samples The samples.
 * @param {!string} original The original bit depth of the data.
 *      One of "8" ... "53", "32f", "64"
 * @param {!string} target The desired bit depth for the data.
 *      One of "8" ... "53", "32f", "64"
 * @param {Array<number>=} outputArray An optional array to write converted samples to.
 *      Useful for writing to typed arrays.
