 * WAV (Windows Wave format)

 * Sun Au / NeXT
 * RCAM (Institut de Recherce et Coordination Acoustique / Musique)

 * Ogg Vorbis

plus its own Audacity Project format (AUP).

See http://audacity.sourceforge.net/manual-1.2/fileformats.html for more info

AUP format
The project file is in an XML format.It links to audio data stored in .au files in the project data directory (projname_data). It can also be linked to other uncompressed source files that have been imported into the project. See File Management Tips for more details.

AIFF format
AIFF is Audio Interchange File Format, a PCM format used on Macintosh and similar computers

To write AIFF files (Export to AIFF) in Audacity 1.2, change the uncompressed export file format from the default WAV format in the File Formats tab of Preferences. Use the list box "Uncompressed Export Format" to select AIFF as the format. If you want to import the files into other programs, it's safest to select 16-bit AIFF. When you click OK in Preferences, the file menu entry will change from Export as WAV to Export as AIFF (and Export selection similarly).
