What is the Visualization Component?

The visualization component displays sound spectrum data in a variety of graphical formats and supports the use of bitmap effects without requiring changes to the component class itself. It draws dynamically based on size and keeps memory consumption to a minimum.

This is simply a very nice tool to integrate audio visualizations within any of your Flex projects and offers the flexibility to due so.
