  • Auto gain level (independent of the auto gain reference obtained during FLAC encoding);
  • Track tempo indicated by BPM (Beats Per Minute);
  • High-resolution waveform (with color coding to display the frequency content);
  • Stripe (schematic visual overview of the whole track);
  • Pitch class (musical key in the circle of fifths).
