You can create one (or more) independent audio files from selected regions in the Audio Bin and Arrange area.
Do one of the following:
Choose Audio File > Save Region(s) As in the Audio Bin.
Choose Audio > Convert Regions to New Audio Files in the Arrange area (or use the corresponding key command, default assignment: Option-Command-F).
Choose File > Export > Region as Audio File in the main menu bar (or use the corresponding key command).
Choose settings in the dialogs that appear.
Browse to and choose the target folder for the new audio files. You can also create a new folder, by clicking the New Folder button.
If you’re only saving one region, you can enter a name for the new audio file. The Hide Extension checkbox hides or shows file extensions (.wav, .aif, and so on) in the Save As field.
Click the Save button.
Note: If you want to simultaneously save several regions as audio files, you should name the regions before using the Save Region(s) as command, as existing region names are applied to the audio files derived from them.
