AU file extension for OS X Sierra, Yosemite:
File with .Au extension is a simple audio file introduced by Sun Microsystems. The AU audio 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 factors of video clock signals. Newer AU sound files have a header that consists of six unsigned 32-bit words, an optional information chunk and then the data (in big endian format).
Although the AU file format now supports many audio encoding formats, it remains associated with the µ-law logarithmic encoding. This encoding was native to the SPARCstation 1 hardware, where SunOS exposed the encoding to application programs through the /dev/audio interface. This encoding and interface became a de facto standard for Unix sound.
