Sun AU
AU (Audio File Format or Sun AU) is a simple audio file format introduced by Sun Microsystems. It's primarily used on Unix-based systems and retains audio data in three parts: a header, a variable-length annotation block, and the actual audio data, making it suitable for simple audio tasks and computer system alerts.
