🎵 Melodix — Self-hosted Discord music bot

Melodix is my pet project written in Go that plays audio from YouTube and audio streaming links to Discord voice channels. It's a continuation of my original buggy prototype.

🌟 Features Overview

🎧 Playback Support

• 🎶 Track added by song name or YouTube/Soundcloud link.
• 📻 Internet radio streaming links (24/7 playback).

⚙️ Additional Features

• 🌐 Operation across multiple Discord servers.
• 📜 Access to recent track statistics and history of play commands.
• 🔄 Playback auto-resume support for connection interruptions.

⚠️ Current Limitations

• 🚫 The bot cannot play YouTube live streams or region-locked videos.
• ⏸️ Playback auto-resume support may cause noticeable pauses at times.
• ⏩ Playback speed may sometimes slightly vary.
• 🐞 It's not bug-free.

You can test out Melodix in two ways:

🔧 How to Set Up the Bot

🔗 Create a Bot in the Discord Developer Portal

To add Melodix to a Discord server, follow these steps:

1. Create an application in the Discord Developer Portal and obtain the APPLICATION_ID (in the General section).
2. In the Bot section, enable PRESENCE INTENT, SERVER MEMBERS INTENT, and MESSAGE CONTENT INTENT.
3. Use the following link to authorize the bot: discord.com/oauth2/authorize?client_id=YOUR_APPLICATION_ID&scope=bot&permissions=36727824
   • Replace YOUR_APPLICATION_ID with your Bot's Application ID from step 1.
4. Select a server and click "Authorize".
5. Grant the necessary permissions for Melodix to function correctly (access to text and voice channels).

After adding the bot, build it from source or download compiled binaries. Docker deployment instructions are available in docker/README.md.
