FFT based motion

If you have access to an FFT that integrate the values over the time, or the FFT at instant t and can do this sum over time, it's possible to use same technics as Time based motion to create motion.

The difference here is, unlike the fGlobalTime , the integrated FFT will increment a value based on the audio frequency values which can help to sync motion with a audio background.

To visualise this in a simple form, let's imagine we focus on the bass and the high of our audio via FFT .
