What is an .AU file?
AU files are audio files saved in the AU Audio format, an early sound file format that Sun Microsystems initially developed for Unix-based systems. AU files can store audio in uncompressed or compressed formats, depending on how they were created, and are often used for simple sound effects and basic audio playback.
You may encounter AU files in older software, legacy systems, or archived audio collections. The format was commonly used for system sounds, alerts, and short audio clips, especially on Unix and early web platforms. File Viewer Plus can play AU files and convert the audio to MP3 or M4A formats to make them more compatible with a wider range of devices and media players.
