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.
