Music Visuals for Mac
Only for Mac
$4.99
Mac
Phosphor Visualizer is a desktop music and audio visualizer for macOS. It reacts in real time to whatever audio is playing on your Mac — Apple Music, Spotify, Safari, YouTube, any app — and renders it as living, beat-synced visuals.
Three display modes
• Float — a small borderless window that stays on top while you work. Drag anywhere 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 with the music.
Features
• 129 hand-tuned scenes — VFD spectrum bars, ray-marched tunnels, orbiting satellites, oscilloscopes, particle fields, phosphor-glow filaments, and more
• Real-time post-processing: kaleidoscope, glow, film grain, RGB split, beat-shake, camera wobble, scanlines, edge sharpening, chromatic aberration
• Save your favorite scene + effects combinations as named presets
• Two audio sources: built-in mic (room sound) or Core Audio Process Tap (exact system audio, macOS 14.4+)
• Record your visuals to MP4 for sharing
• Media buttons to control your favorite sound or music source
• Menu bar icon with quick scene picker, mode switcher, and playback controls
• Apple Silicon–optimized, drawn entirely on the GPU
• No accounts. No telemetry.
Phosphor was built to make listening feel visual again. Put on an album, pick a mode, and let it do its thing.
Requires macOS 14.4 or later, Apple Silicon.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
New scene
- HEART — ray-marched 3D heart, asymmetric pump driven by the beat, with a radiating particle field around it.
Improvements
- A live cyan equalizer now sits in the menu bar reacting to whatever Phosphor is listening to. Click it to open the popover.
- Settings → MENU BAR EQ has two toggles: ENABLE (default on) and ANIMATE. Disable ANIMATE to keep the EQ as a static logo if you'd rather nothing in your menu bar move around.
Reliability
- Phosphor no longer goes silent after the Mac sleeps. The audio feature pipeline now resets correctly on wake, so the visualizer stays in sync with audio after long idle periods.
- Render-engine fix that resolves drift and mistimed effects in some scenes.
