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.

AAC Converter

What is a AAC file?

Advanced Audio Coding or AAC file format is an Apple iTunes and iTunes Store default encoding method for music files. It is similar to MP3 format, except it has a better sound quality. This type of file sometimes uses the AAC file extension, but it is wrapped mostly in the M4A file container. It means that they often carry the M4A file extension instead of ACC. Mac users can open AAC files with iTunes, and all Windows fans use VLC, Media Player Classic (MPC-HC), Windows Media Player, MPlayer, Audials One, etc. In case you have a player that doesn't support this type of file, you can always convert it to another format.
