GhostDeck
GhostDeck is an offline music player for macOS with a retro modular deck interface, local audio, M3U playlists, equalizer controls, and five low-poly worlds.
Offline music player with a retro deck interface
GhostDeck is an offline music player for macOS that plays audio files from folders on your Mac. It uses a classic deck-style interface with four snap-together modules for playback, playlists, equalizer controls, and visual feedback.
While a track plays, its artwork appears in a slowly turning jewel case over one of five low-poly scenes. The native Metal renderer generates the environments on the Mac, while controls such as playlist management, keyboard shortcuts, media keys, and dockable windows support desktop listening without a network connection.
Features
10-band equalizer
Shape playback with a 10-band equalizer, preamp, live response curve, and presets including Flat, Bass, and Headphones.
Playback visualisation
View a 32-band analyser, scrolling track title, and elapsed or remaining time while music plays.
Five rendered worlds
Choose among five low-poly worlds, then shift a theme’s hue across the colour spectrum. The scenes are rendered in Metal with generated geometry, lighting, fog, reflections, and vignette effects.
Modular desktop interface
Use four modules that snap together, dock the deck near a screen edge, and select a 1x–4x pixel scale. Keyboard shortcuts, media keys, the menu bar, and the Now Playing widget support control outside the main window.
Offline, native operation
The native macOS app runs offline, has no account or analytics, and is sandboxed to folders the user opens. The site states that the app is about 12 MB and idles at a few percent of one CPU core.
Use cases
Listening to a local music library
Open a music folder and play files recursively without sending the library to an online service. The app can use embedded artwork or nearby cover files, with a generated sleeve when neither is available.
Managing desktop playlists
Load or save M3U playlists, shuffle or repeat tracks, and control playback with keyboard shortcuts, media keys, the menu bar, or the Now Playing widget.
Ambient background listening
Select one of five scenes, adjust its hue, choose an equalizer preset, and dock the deck in a screen corner while it runs alongside other Mac work.
Tuning and monitoring playback
Use the 10-band equalizer, preamp, live response curve, spectrum analyser, and elapsed or remaining time display for more detailed playback control.
