Standard includes the entire main window, including metering, Mid/Side and Mix Check. Pro adds the eleven Analysis Lab tools, A/B/C/D comparison in Live, whole song or selection mode, and the PDF comparison report. The audio quality of the comparison is the same.

To follow its movement use Live. The comparison report has ten pages that can be printed and saved in PDF via Windows.
