Logic Pro X: Project Audio Browser overview
The Project Audio Browser shows all audio files and regions that have been added to or recorded in your project, whether or not they are used in the Tracks area. Regions shown in the Project Audio Browser that are not used in the Tracks area are indicated in red.
You can add, edit, delete, and rename audio files and regions in the Project Audio Browser. You can add audio files to your project by dragging them from the Project Audio Browser into the Tracks area, where you can edit, move, and copy them.
You can also open a separate Project Audio window.
