Meter visualisation: Shows the peak level in db and the average rms in db. The center meter is the dynamic range of the music (see also http://dr.loudness-war.info). Low dynamic range turns red, medium dynamic range from orange to yellow and great dynamic range is green.
Loudness visualisation: Shows the loudness over time of the song. The black line is the average rms in db and the colored line is the dynamic range (same colors and range as the Meter visualisation).
