Sound, visualized.
Mood, reflected.

Xpress is a Spotify-driven ambient particle visualizer designed specifically for secondary monitors. Watch your music shape a responsive, ACES-tonemapped 3D environment in real-time.

Spotify API Notice: Currently in closed developer preview due to Spotify developer quota restrictions. Playback connection is limited to pre-authorized accounts.

An engine driven by your taste.

Xpress features a dynamic MoodEngine that extracts musical profiles to alter rendering states on the fly. It translates Spotify track signals into vector fields, blending five motion modes.

From gentle drifting vortex fields for acoustic tracks to high-energy bursts and attractors for heavy beats — your music literally shapes the particle behavior.

Cinematic Post Pipeline.

Built with custom Three.js shader passes, Xpress implements a professional ACES filmic tonemap and post-processing stack.

With adjustable isotropic bloom, subtle chromatic aberration, vignette, and film grain, the visualizer looks premium and soft — glowing, rather than glaring.

ACES Filmic Tonemapper ENABLED
Isotropic Bloom Intensity 0.65
Chromatic Aberration 0.08
Post Processing Pipeline Active (4K HDR support)
