Normalize audio regions in the Tracks area in Logic Pro for Mac
You can normalize the gain of selected regions in the Tracks area, without opening the regions in the Audio Track Editor. In Logic Pro for Mac, the Normalize Region Gain menu command is non-destructive: The original file isn’t altered, only the normalized region.
When Enable Complete Features is selected in Logic Pro > Settings > Advanced, the Normalize Region Gain command is available in the Functions menu.

In the Affect pop-up menu, choose whether individual regions, individual tracks, or the entire selection are normalized.
In the Algorithm pop-up menu, choose the normalization algorithm to use.
Use the Target Level value slider to set the intended level of normalization (in decibels).
