This is a funky signal analyzer which simulates the famous Focal Grande Utopia EM Hifi speakers.
The analyzer listens to the left and right audio channels on the master track, and moves the various speaker cones including tweeter according to the audio stream's frequency content. While it's primarily a fun tool, the analyzer should display the frequency content correctly (approximatively): Sub from 20..80Hz, bass from 80..220Hz, mids from 220..2200Hz, tweeter from 2200..18200Hz.
If one clicks on Dirk Nowitzki, a little fact sheet is shown.
