    shout.setHost('127.0.0.1');
    shout.setProtocol(0);
    shout.setPort(8000);
    shout.setPassword('icecast-stream-pass');
    shout.setMount('/icecast-stream-mount');
    shout.setUser('source');
    shout.setFormat(0);
    shout.open();
    
    const fd = await fs.promises.open(path.resolve(__dirname,'audio.ogg'), 'r');
    const tmp = Buffer.allocUnsafe(1024 * 4);
    
    while(1) {
        // Read audio data from file
        const {bytesRead} = await fd.read(tmp, 0, tmp.byteLength, null);
        if(bytesRead) {
            //Send audio data to icecast server
            shout.send(tmp.buffer.slice(0, bytesRead));
        } else {
            break;
        }
        shout.sync();
    }
    shout.close();
}

Example 2 - MP3

import {Shout} from 'libshout-node';

async function run() {
    const shout = new Shout();
    
    shout.setHost('127.0.0.1');
    shout.setProtocol(0);
    shout.setPort(8000);
    shout.setPassword('icecast-stream-pass');
    shout.setMount('/icecast-stream-mount');
    shout.setUser('source');
    shout.setFormat(1);
    shout.open();
    
    const fd = await fs.promises.open(path.resolve(__dirname,'audio.mp3'), 'r');
    const tmp = Buffer.allocUnsafe(1024 * 4);
    
    while(1) {
        // Read audio data from file
        const {bytesRead} = await fd.read(tmp, 0, tmp.byteLength, null);
        if(bytesRead) {
            //Send audio data to icecast server
            shout.send(tmp.buffer.slice(0, bytesRead));
        } else {
            break;
        }
        shout.sync();
    }
    shout.close();
}

Example 3 - Endless Stream

import {Shout} from 'libshout-node';

async function run() {
    const shout = new Shout();
    
    shout.setHost('127.0.0.1');
    shout.setProtocol(0);
    shout.setPort(8000);
    shout.setPassword('icecast-stream-pass');
    shout.setMount('/icecast-stream-mount');
    shout.setUser('source');
    shout.setFormat(0);
    shout.open();
    
    const fd = await fs.promises.open(path.resolve(__dirname,'audio.mp3'), 'r');
    const tmp = Buffer.allocUnsafe(1024 * 4);
    
    while(1) {
        // Read audio data from file
        const {bytesRead} = await fd.read(tmp, 0, tmp.byteLength, null);
        if(bytesRead) {
            //Send audio data to icecast server
            shout.send(tmp.buffer.slice(0, bytesRead));
        } else {
            //Send empty buffer to icecast server
            shout.send(tmp.buffer.slice(0, 1024*4));
        }
        shout.sync();
    }
    shout.close();
