Your personal music server.
SOUND is a private, lightweight music server that transforms your personal music collection into a modern streaming service.
Once SOUND is installed on your computer, you can connect your personal music collection (using any folder on your computer or a Google Drive) to use WAVE to access and stream your music from anywhere in the world.
SOUND is available to all STREAMLINE users, even free accounts. SOUND integrates your music with the STREAMLINE platform with a single click. Your personal library blends seamlessly with official albums purchased on STREAMLINE .
Self-Hosted
Run SOUND on your own hardware. Your music stays on your devices, under your complete control. Available to all Streamline users—even free accounts.
Privacy First
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.
Audiophile Grade
Stream lossless FLAC, high-resolution audio, and any format you prefer—no transcoding, no compression. Your music in its original quality.
Secure Remote Access
We use Cloudflare Tunnels by default for secure, encrypted remote access. Want more control? Use your own Cloudflare Tunnel or Tailscale setup.
Lightning Fast
Built with Node.js for high-performance streaming. IndexedDB caching ensures instant library browsing, even with 50,000+ tracks.
Real-Time Sync
WebSocket-powered metadata updates across all connected devices instantly. Edit once, update everywhere.
For over twenty years, the music industry has been split: mainstream streaming services control what you can access, while self-hosted solutions 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.
This creates a unique experience: browse STREAMLINE's official album 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. Stay tuned.
