Plug Phosphor into your Mac's system audio and watch any track turn into a beat-synced light show — EDM drops, lofi loops, dubstep wobbles, hip-hop, techno, classical strings, all from any app, all in real time. Float it on your desk, fill the screen, or set it as your wallpaper.
Download Phosphor from the Mac App Store. Sandboxed, signed, notarized, and ~12 MB.
One-time permission. Phosphor uses Apple's Core Audio Process Tap — the same API ScreenCaptureKit uses. No virtual driver, no kext.
Open any music app. Phosphor is already listening. Pick a scene, stack effects, and lean back.
No. Audio is read in-memory and never leaves your Mac. Phosphor has no analytics, no accounts, and no network calls beyond App Store update checks.
Phosphor is Apple Silicon only (M1 and later). It uses Metal 3 features that are not available on Intel.
Yes. Phosphor taps the system output, regardless of which device is currently selected.
Phosphor visualizes whatever is routed to your main output. If you have a separate cue/headphone bus, that path will not be visualized — by design.
