Sound Visualization
Data Analysis Project · University of Vienna
About
This tool transforms audio into real-time visual art. Upload a track, use a demo,
or plug in your microphone — then watch the music become color, shape, and motion.
Each visualization mode reacts differently to bass, mid, and treble frequencies.
How to use
- Choose an input — upload an audio file, pick a demo track, or select Microphone.
- Press Play (or "Start Mic") to begin.
- Pick a visualization from the dropdown — each one responds to sound differently.
- Adjust the palette, background and reactivity to your taste.
- Hit Fullscreen for the full experience. Hover the top-right corner to exit.
Visualization Modes
A · Waveform
Classic oscilloscope — raw audio signal drawn across the canvas.
B · Optical Flow
Flowing lines distorted by bass and mid frequencies.
C · Architect
Accumulating geometric lines and flashes that build over time.
D · Color Blend
Overlapping painted rectangles driven by volume and treble.
E · Spectrogram
Scrolling time–frequency map. Bass at bottom, treble at top.
F · Rimington
Historical color-organ: each musical note maps to a spectrum color.
Options
Color Palette — 7 schemes (Bauhaus, Cyber, Carbon, Sunset, Ocean, Earth, Midnight).
Dark / Light background — switch for any visualization.
Reactivity — from subtle to extreme visual response.
Pause — freezes the canvas as a snapshot.
