FFmpeg with custom parameters in Discord.js

Installation:

npm install discord.js-arbitrary-ffmpeg --save

Example usage:

const Discord = require('discord.js');
const playArbitraryFFmpeg = require('discord.js-arbitrary-ffmpeg');

const objBot = new Discord.Client();

// ... login and connect to a voice channel so you get a voice connection ...

// These params will play a sound file in a much faster speed.
// Standard KHz rate is 44.1.
let arrFFmpegParams = [
    '-i', 'sounds/funny-meme-sound.mp3',
    '-filter:a', 'asetrate=r=66K'
];

const objStreamDispatcher = playArbitraryFFmpeg(
    objVoiceConnection, // A VoiceConnection from Discord.js
    arrFFmpegParams,
    {volume: .25} // Optional stream options (same as for playFile, playStream, etc.)
);
