Music interpretation	FFT

analysis results

amplitude → react to trends in music
Dynamic reaction to signal history
Output difference to previous average and scale
between min/max (updated along the music)

X movement, Y movement, color change

Pitch analysis:

Analog → digital → FFT

Every 7s: calculate RMS of amplitude → normalized value

→ Plots:
