How to Convert an MP3 to AU
Unix Audio (au) is the standard audio file format created by Sun Microsystems and used by Sun, Unix and Java. "mp3" is a very common format used by many systems. If your music collection is primarily in the "mp3" format and you have a song you would like to use in a Java program on the Internet, converting the "mp3" file to an "au" file will help you do that.
