The navigation graph of mp3DirectCut shows fast MP3/AAC data instead of decoded PCM. In many
cases it contains only higher frequencies. Also it can be too high or too low, in these cases you can adjust the height
in the Options menu (or Numpad +/-). In rare cases the display shows nothing. Silences may appear with a high level in some
cases. The real audio level is always shown while play with the Level meter on the right.
