What is an Au File?

Au is a basic audio file format developed by Sun Microsystems. Essentially, Au is the same as the SND format and commonly seen on NeXT systems and early web pages. However, newer media players may fail to open Au files, and we’d best convert Au to a common format like WAV or MP3 if we want easier playback.

In the next part, we will go over how to convert Au to WAV with a powerful audio converter. Read on if you’re interested.

(* Note that AU files can also be AUP files associated with Audacity. Please refer to this article to learn how to convert AUP files.)
