Capsize Audio Visualizer

Capsize Audio Visualizer is a native Linux and Windows desktop app for turning music into real-time visuals. Pick your system audio monitor source, choose a shader, and dial in the look while the visuals react to bass, mids, and treble.

It is built for people who want a fast, local visualizer for music playback, streams, experiments, and ambient displays. The current desktop edition includes multiple shader scenes, hardware-accelerated OpenGL rendering, persistent settings, and a neon shape visualizer for sigil-like geometric compositions.

Features

- Real-time audio-reactive visuals driven by bass, mid, and treble bands

- Five shader modes: Neon Shapes, Audio Rings, Plasma Nebula, Cosmic Web, and Rainbow Prism

- Neon shape scene controls, including position, size, rotation, color, audio band assignment, drag placement, persistence, and reset

- Dynamic per-shader controls with sliders and color pickers

- PulseAudio / PipeWire monitor-source workflow for visualizing music from your speakers

- Fullscreen mode for ambient display or performance use

- Native C++ / Qt6 / OpenGL desktop app

Linux Audio Note

For music playback, choose a monitor source in the app, such as Monitor of Built-in Audio or another source marked (Monitor). That listens to your speaker output directly. If you pick a physical microphone instead, the visualizer will react to room sound.

System Requirements

- Linux x86_64  or Windows

- OpenGL 3.3 or newer

- PulseAudio or PipeWire with PulseAudio compatibility

- Qt6 runtime libraries

Debian/Ubuntu users can install common runtime dependencies with this command:

sudo apt install libqt6core6 libqt6gui6 libqt6widgets6 libqt6opengl6 libqt6openglwidgets6 libpulse0 pulseaudio-utils libmp3lame0

Web Demo

There is also a browser version at https://av.capsizegames.com/ if you want to try the visual style before buying the desktop build. The desktop app is the fuller native version with direct PulseAudio source selection and desktop settings persistence.
