Phosphor
What Phosphor is
Phosphor is a macOS visualizer that turns computer audio into beat-synced graphics without a plugin, account, or setup. It can analyze system audio from Apple Music, Spotify, Safari, and YouTube, then display scenes in a floating window, fullscreen, or as animated wallpaper behind desktop items. Listed scenes include Phosphor, Bassdrop, Rainbow Bars, Tunnel, Nebula, Orbits, Supernova, Kaleido, Oscilloscope, and Terrain FFT. Users can stack effects such as CRT, bloom, vignette, grain, chroma, pixelation, and blur, save presets, and layer a second scene with blending and crossfade controls. Visuals with system audio can be recorded to H.264 MP4 or ProRes 422 LT MOV in the Movies folder, with export up to 4K. Metal rendering reaches 60 fps, or 30 fps in Low Power mode. The app runs locally, makes no network requests, and discards analyzed audio immediately. It costs 6.99 USD as a one-time purchase.
