Windows Subsonic Client Link

No built-in lyrics fetching. Metadata editing is not possible—read-only. That’s fine for a streaming client but annoying if you like correcting tags on the fly.

Feature set is server-dependent. The client is just a viewer; don’t expect editing or advanced library management. 6. Resource Usage Official Java Client: Idle: ~80–120 MB RAM. Playing FLAC: ~150 MB. CPU usage: 0–2%. Surprisingly lean for Java. However, startup time is slow (5–10 seconds).

Official client: space to play/pause, arrow keys for volume/navigation. Basic. Supersonic: adds global hotkeys (even when app is in background) – huge plus. windows subsonic client

This is a sore spot. The official client does not support gapless playback (there’s a tiny gap between tracks). Supersonic handles gapless reasonably well, but it’s not as seamless as Roon or foobar2000. For live albums or classical music, this is frustrating.

A massive improvement. Built on Electron (yes, resource-heavy, but modern), Supersonic offers a clean, dark-themed interface, smooth scrolling, proper album grid view, and an integrated now-playing queue that makes sense. It feels like a modern music player (similar to Plexamp lite). It also supports offline caching better than the official client. No built-in lyrics fetching

Much better. You can choose cache size, see downloaded files by album art, and it intelligently pre-caches the next few tracks. Offline mode activates automatically after 30 seconds of no server connection. Sync progress is shown clearly.

Idle: ~200 MB RAM. Playing: ~250–300 MB. CPU: 1–5%. Not terrible for Electron, but heavy compared to native apps. Feature set is server-dependent

Avoid the official client unless you love nostalgia. Use Supersonic for a tolerable daily driver. 3. Playback Performance Audio Quality: Excellent. Both clients support direct streaming of FLAC, MP3, AAC, and OGG. No transcoding by default—the server sends the original file. Bit-perfect playback is achievable if your Windows audio chain is clean (WASAPI exclusive mode is not built-in, though). Latency is low: tracks start within 1–2 seconds on a good connection.
