What is a AC3 file?
A file with an AC3 extension uses lossy compression to reduce the overall size of a file. AC3 stands for Audio Codec 3 created by Dolby Laboratories. This type of file supports the surrounding sound. It has a separate track for each of six speakers of a surround sound setup. One speaker is dedicated to low-frequency subwoofer output, while others are dedicated to the normal range. It means that the AC3 format has a 5:1 surround sound setup. This type of file is mostly used for audio in movie theaters, video games, and DVDs.
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.
