Vizzy is a straightforward music visualizer that generates spectrum-based animations with customizable colors and backgrounds. It's clean, simple, and effective for basic visualizations — spectrum bars, circular spectrums, and waveforms. Zeltor Labs goes far beyond spectrum display with MusicMind's 14 cognitive layers powering 30+ GPU-accelerated effects, auto-direction across chords, tension, and rhythm, frequency-band reactivity, and post-processing.

Key Differentiators
30+ effects vs. 8 spectrum styles
Vizzy offers spectrum bars, circles, and waveforms in different arrangements. Zeltor offers more than 30 effects spanning particles, fractals, ecosystems, neural scenes, and more — each with unique audio reactivity.
Scene-aware direction
Vizzy plays one effect for the entire video. Zeltor detects sections (verse, chorus, drop, bridge) and assigns different effects with transitions — creating a directed visual experience.
Cinematic post-processing
Zeltor's PostFX chain (bloom, grain, chromatic aberration, vignette, color correction) adds cinematic depth. Vizzy offers basic color customization without post-processing.
MusicMind: 14 Layers of Musical Cognition
Vizzy reads one audio dimension (FFT spectrum). Zeltor's MusicMind reads 13 — from chord progressions and tonal tension to rhythmic genome and creative DNA. It's the difference between hearing and understanding music.
