When you are recording, the track name is used as the default filename. Subsequent recordings made on this track are assigned an ascending numerical suffix. “Audio 1” is named “Audio 1_01,” “Audio 1_02,” and so on. If the track is not named, the name of the channel strip that the track is routed to is used. You can rename tracks in the Arrange track list and Mixer (see Naming Tracks in the Arrange Area and Renaming Tracks in the Mixer).
