Web-audio-write NPM

web-audio-write

Write data to any web-audio node.

Usage

import createWriter from 'web-audio-write'

const context = new AudioContext()
const write = createWriter(context.destination)

for (let n = 0; n < 10; n++) await write(noise())
write.end()

function noise (frame=1024, channels=2) {
	let data = new Float32Array(channels * frame)
	for (let i = 0; i < data.length; i++) {
		data[i] = Math.random() * 2. - 1.
	}
	return data
}

API

`write = createWriter(node = audioContext.destination)`

Create a function, writing any data to any AudioNode. Channel number and sample rate is derived from destination node.

`async write(samples)`

Send data to the destination node. samples can be an array with planar channels layout or a list of arrays, with floats in -1...+1 range. Returns promise that is resolved when data chunk is being consumed, that's a good place to feed more data.
