You can follow the steps below to match a source track and a target track:
Select/create Source / Target tracks
import audio files into these two tracks (not needed if there are audio files on these tracks already )
insert Pro EQ plug-in on the source track
loop a section that you want to match
Import the audio from the target track as a side chain in the Pro EQ plugin on the source track
Play the source and target tracks at the same time (the looped section), and click Match button to start the EQ Match process
When you see the Blue and Purple line becoming steady, that means the matching is completed.
