Coming soon — Audio-reactive visuals

Lumina is a native macOS music player built around a real-time, audio-reactive Metal visualizer — architected so any source, from local files to DRM streaming, drives the same field of light.
Coming soon — Mac App Store
The problem
Visualizers go blind on the good stuff
Most visualizers can only react to audio they decode themselves, so protected streaming — Apple Music, Spotify — gets no visuals at all. Lumina taps the Mac's post-mix output through a Core Audio process tap (macOS 14.4+), so the picture reacts to whatever is actually playing, no matter where the sound came from.
Capabilities
What Lumina does, precisely.
Two paths to the waveform
A playback-engine tap reads raw PCM from local files; a system-audio tap captures the Mac's output post-mix. Switch between them live — the second works with anything, DRM included.
A particle field, driven by frequency
An Accelerate/vDSP FFT resolves 64 log-spaced bands plus bass, mid, and treble energy, feeding an additive GPU particle field that pulses at a steady 60fps.
Any source, one boundary
Everything visual depends on a single MusicSource protocol. Local playback works today; Apple Music and Spotify slot in behind the same clean seam without the visuals ever caring.
Native to the metal
Swift 6, Metal, and Core Audio with nothing in between — a player that opens instantly, idles quietly, and holds sixty frames on battery.
