AU Converter

What is a AU file?

This type of file represents a simple audio file that was primarily common on NeXT systems and early Web pages. The AU file format was, at first, used by Sun or some similar Unix-based machine, but now, it can be opened with other audio programs as well. To reproduce this file format, you can use Nullsoft Winamp, Apple QuickTime Player, Microsoft Windows Media Player, RealNetworks, RealPlayer Cloud, or Adobe Audition CC. Although AU files are quite small and have poor sound quality, they store information in three sections. The first one is called header, with a maximum of 24 bytes. Next, there’s a variable-length annotation block. And last but not least, there’s the audio data itself.
