Your personal music server.
SOUND is a private, lightweight music server that transforms your personal music collection into a modern streaming service. SOUND is available to all Streamline users, even free accounts, making it extremely easy to take control of your music library.
SOUND integrates your music with the Streamline platform with a single click. Your personal library blends seamlessly with official Streamline albums..
Run SOUND on your own hardware. Your music stays on your devices, under your complete control. Available to all Streamline users—even free accounts.
We take privacy seriously: Streamline has zero access to your SOUND database or personal music files. We only store internal API keys for integration—nothing else.
Stream lossless FLAC, high-resolution audio, and any format you prefer—no transcoding, no compression. Your music in its original quality.
We use Cloudflare Tunnels by default for secure, encrypted remote access. Want more control? Use your own Cloudflare Tunnel or Tailscale setup.
Built with Node.js for high-performance streaming. IndexedDB caching ensures instant library browsing, even with 50,000+ tracks.
WebSocket-powered metadata updates across all connected devices instantly. Edit once, update everywhere.
For over twenty years, the music industry has been split: mainstream services like Spotify control what you can access, while self-hosted solutions like Plex and Subsonic leave you isolated from discovering new music.
SOUND + Streamline changes this. Your personal library appears side-by-side with official albums in a unified interface. The UI blends so seamlessly you can't tell where your collection ends and Streamline's catalog begins.
This creates a unique experience: browse Streamline's marketplace to discover new artists, purchase official releases to support musicians directly, then instantly integrate those albums with your existing collection. It's the best of both worlds—complete ownership of your library with the discovery power of a modern platform.
And yes, we're planning to open-source SOUND in the future. Stay tuned.
