What is a .AU file?

The AU file extension is a data format associated to Sun Microsystems. AU files store the data in three parts: a header (24 bytes), a variable length annotation block, and the actual audio data. These are audio files used primarily on Sun or other Unix-based machines and have been adopted by several audio programs like Adobe Audition, Java and QuickTime. They are uncompressed sound recordings, stored in a different format. They are known as Unix audio files or audible files which are used to embed and play audio files on Web pages.
