Phosphor Visualizer

Turn any audio on your Mac into living, beat-synced visuals — Spotify, Apple Music, YouTube, any app. 120+ hand-tuned scenes, a live wallpaper mode, and one-tap MP4 recording for Reels, Shorts & Spotify Canvas.

Phosphor reads whatever is playing on your Mac and renders it in real time — no setup, no plugins, no uploading your music anywhere. Pick a scene, pick a mode, and let your screen move with the music.

THREE DISPLAY MODES

• Float — a small borderless window that stays on top while you work. Drag to move, corner-drag to resize.

• Fullscreen — edge-to-edge visuals for full immersion.

• Wallpaper — Phosphor becomes your desktop, animated behind your icons and windows. Put on an album and your whole screen breathes.

MAKE CLIPS WORTH POSTING

• One-tap MP4 recording — capture a scene reacting to a track and drop it straight into Reels, Shorts, or a Spotify Canvas.

A DEEP, GROWING LIBRARY OF SCENES

VFD spectrum bars, ray-marched tunnels, orbiting satellites, oscilloscopes, particle fields, phosphor-glow filaments, and more — each one tuned to react to every transient. New scenes land in regular updates.

REAL-TIME POST-PROCESSING

Kaleidoscope, glow, film grain, RGB split, beat-shake, camera wobble, scanlines, edge sharpening, chromatic aberration. Stack them, then save any scene + effects combo as a named preset.

BUILT FOR YOUR MAC

• Two audio sources: built-in mic (room sound) or Core Audio Process Tap (exact system audio, macOS 14.4+)

• Media keys to play, pause, and skip tracks in your music app

• Menu bar icon with quick scene picker, mode switcher, and playback controls

• Apple Silicon–optimized, drawn entirely on the GPU

• No accounts. No telemetry. Everything runs on your Mac.

Phosphor was built to make listening feel visual again — the spirit of Winamp and MilkDrop, rebuilt for the modern Mac.

Requires macOS 14.4 or later, Apple Silicon.
