module.repeater(radio)

Simply a repeater for ReadableStream. Suitable when you face some performance issue in single duplex. Return a function.

const fs = require("fs");
const openradio = require("openradio");
const radio = openradio(); // Broadcaster
const repeater = openradio.repeater(radio); // Create a repeater of "radio" duplex.

// The repeater is responsible in writting incomming buffer from "radio" duplex
// for multiple WriteableStream at the same time without decreasing the duplex performance.

let r1 = repeater(fs.createWriteStream("stream1.mp3"));
let r2 = repeater(fs.createWriteStream("stream2.mp3"));
let r3 = repeater(fs.createWriteStream("stream3.mp3"));

// Assume that we're enough writting buffers to fs.createWriteStream("stream2.mp3")
// And so we're gonna stop writting.
r2();

// Even though the repeater stop writting, It's WriteableStream is not ended.
// So you need to end them manually.
