Ecktra

[eutro]

Description

Ecktra is an easily extensible, expressive audio visualization DSL in Racket.

The main product of this project is the audio visualizer language itself, rather than any individual visualizer or its output.

Examples below were generated using as input this brief clip I wrote myself (using Ardour). Similar, and usually even better, output can be produced with songs by professional musicians, such as those published by NCS.
