Music visualization

"Music visualizer" redirects here. For a minimal style of music video, see music video.

Music visualization or music visualisation is animated computer-generated imagery based on a piece of music. The imagery is usually generated and rendered in real time, synchronizing with the music as it is played. The feature is found in electronic music visualizers and media player software.

Visualization techniques range from simple ones (e.g., a simulation of an oscilloscope display) to elaborate ones, which often include a number of composited effects. The changes in the music's loudness and frequency spectrum are among the properties used as input to the visualization.

Effective music visualization aims to attain a high degree of visual correlation between a musical track's spectral characteristics such as frequency and amplitude and the objects or components of the visual image being rendered and displayed.

In modern usage, a basic music video that does not feature synthetic imagery, but nevertheless does not present a defined narrative (although it may comprise footage of real people or events), may also be termed a "visualizer".
