Four visualizers run on the GPU. Nebula orbits roughly 100,000 simulated particles around a bass core, Spectrum Tunnel flies through a tube whose angular slices are the live spectrum, Aurora layers ribbons that ride the waveform, and Bars builds a studio console of LED columns, analog VU meters and moving faders.
It names the track playing in Music or Spotify without asking for a single permission — the players broadcast it. Point it at system audio, any input device, or a file on disk; five palettes and global sensitivity and speed apply across every visualizer.
General notes
01.Four GPU visualizers — Nebula, Spectrum Tunnel, Aurora and Bars
02.64-band log-spaced FFT, so tone shapes the picture rather than volume alone
03.Now-playing title, artist and album with no permission prompt
04.System audio, any input device, or a local file as the source
05.Five palettes — Prism, Ember, Ocean, Violet and Mono
06.Universal build for Apple silicon and Intel, macOS 15 or later
07.Auto-hiding chrome, so real fullscreen leaves only the visualizer
