The Au file format is a simple audio file format introduced by Sun Microsystems. The format was common on NeXT systems and on early Web pages. Originally it was headerless, being simply 8-bit μ-law-encoded data at an 8000 Hz sample rate. Hardware from other vendors often used sample rates as high as 8192 Hz, often integer multiples of video clock signal frequencies. Newer files have a header that consists of six unsigned 32-bit words, an optional information chunk and then the data (in big endian format). Thanks to its sound quality Au has become quite popular. Today you can play back Au files in your favorite player (or your car or home stereo) just like you would an MP3 file.
