From Morgan-Hocker Group:
Vusic is interactive music response software that 'listens' to music CDs and generates colorful animations in response to the beats. Vusic works with any music CD put into a CD-ROM drive. Users can create custom graphic elements or choreograph original animations that can be saved and attached to song tracks on a CD or shared with others. In addition, these animations can be encoded onto the music CDs themselves. Vusic can easily be configured to respond to any kind of sound input, such as mixers, microphones, guitars, and synthesizers.
