	Audio (AU) sample file format from Sun Computers, ~~are~~ a good example of a simple file type consisting of a header followed by data. There are actually two kinds of AU file. The suffix .au was originally introduced by Sun for headerless audio files containing compressed audio sampled at 8,000 samples per second. Subsequently, the [[SND]] format was adopted on NeXT computers, and is the same as the AU format. AU files consists of a header with the following format followed by a single chunk of audio data. The numerical values in the header must be stored in big-endian format.
