Every feature built because we actually use them. No fluff, no marketing copy, just what's in the box.
A full screen big-screen view for the TV or 4K monitor: rotating artist photography (or your own album covers), a real scrubbable audio waveform, the track’s format and DR on display, optional giant synced lyrics. Pick Stage, hit Showtime.
Every track scored with a TT-style dynamic range (DR) analysis. Browse a new Hi Res tab grouping your library into Reference Grade (DR 14+), Audiophile, Balanced, Compressed, and Brick Walled tiers. Spot loudness war casualties at a glance. Real math, no cloud.
Plug a USB CD drive into your NAS and rip discs straight into your library. MusicBrainz lookup, full Vorbis tags, embedded artwork, multi disc CD 1 / CD 2 subfolders, correct medium selection. Zero hand renaming.
Found a duplicate album in your library? The Mastering Versions page surfaces every pressing you own with their DR values side by side, so you know which copy is the better master before you press play.
SugarSpin shows the exact address you are currently using to open the app. It does not guess or configure your home network, internet access, or VPN. Remote access is optional and managed separately by the server owner.
Press play wherever you are and that device becomes the one making sound. The Stream To sheet shows every device and BluOS / NAD speaker from any screen, phone included — tap to move the music there. Name your devices, set a default so playback lands where you want, and sign one out, all from the one sheet. Always in sync.
Group favorite albums onto Shelves, like a record shelf. Then arrange your Shelves, Playlists, and Liked Songs exactly how you like, just hold and drag. The tiles slide apart to make room and your order is saved, right through to the Home screen.
A live meter bridge in Display Settings: peak, loudness (LUFS), stereo width, dynamic range, LRA, and bass energy, all reading off whatever's playing in real time. It only watches the sound, never changes it. For when you like to see your music as well as hear it.
FLAC, ALAC, AIFF, WAV, OGG, OPUS, AAC, M4A, MP3. Your files stream untouched by default. Hi res masters arrive at the player exactly as you ripped them. When a device can't play a format natively, SugarSpin transcodes to lossless FLAC on the fly so it still plays.
Embedded artwork extracted automatically. Missing covers? One button fetches them from MusicBrainz instantly.
Fully responsive web app. Desktop, tablet, phone. Add it to your home screen for a fullscreen app like experience.
Your library, listening history, and core playback stay on your own server. Optional artwork, lyrics, updates, purchases, and remote-access tools may contact their respective third-party providers.
Auto organized by genre with beautiful colored tiles. Rock, Jazz, Hip Hop, Classical, Soundtrack, browse the way it should be.
Create custom playlists, mark favorites, build your perfect listening experience. Persists across sessions and updates.
Control playback from your phone while audio plays on your desktop. All devices stay in sync in real time.
CarPlay is built into the official SugarSpin iPhone app. Android Auto requires a compatible third-party Subsonic app; third-party access is available on Pro and Gold, and exact dashboard support depends on the app selected.
Native BluOS control. Pick a discovered Node, Powernode, Pulse, M10, or M33 and stream directly to your hi-fi gear. The speaker must be reachable from the SugarSpin server on the local network.
VU meters, spectrum analyzer, oscilloscope, and wave forms animate from the actual audio while casting. 30 fps server decoding.
Karaoke style scrolling, full screen Spotlight, or gentle Wave animation. LRCLib with NetEase fallback for huge coverage gains.
A fresh 25 track playlist every day, mixed from your favorites, dormant albums, and deep cut surprises. Algorithmic but human feeling.
Quiet tracks and loud tracks sit at consistent levels. Reads industry standard ReplayGain tags. Off / Track / Album modes.
A built in vacuum tube saturation stage that adds gentle even order harmonics. Four presets plus a custom Drive slider. Source files never modified.
A Now Playing view with four photoreal vacuum tubes glowing amber over a warm bokeh field, breathing with the song’s loudness.
