Cavalier is an audio visualisation application that transforms music and other sound into animated graphics. It uses Cava for audio spectrum processing and presents the resulting visualisations through a customisable graphical interface.
The application is intended for users who want an attractive visual accompaniment to their music. Rather than offering scientific measurements, it provides different drawing styles and appearance settings for creating personalised animations.
Cavalier can display visualisations in a conventional window or a borderless presentation. Its controls allow users to experiment with colours, gradients, drawing modes and audio-response settings.
This is free and open source software.
Key Features
- Eleven visualisation modes including bars, waves, levels, particles and other patterns.
- Animated displays that respond to the frequency content of music.
- Configurable spectrum sensitivity and frame rate.
- Adjustable number and appearance of frequency bars.
- Audio smoothing and noise reduction controls.
- Customisable drawing directions and mirrored effects.
- Single colours, gradients and images for foreground and background.
- Borderless window mode for a cleaner visual presentation.
- Controls for bar roundness and other drawing characteristics.
- Command-line options for changing visualisation colours.
