What is a AU file?

AU is a simple audio format developed by Sun Microsystems, originally for Unix systems. It was once common in early internet applications and multimedia software. AU files can contain various types of audio data, including uncompressed PCM or μ-law encoded samples.

Although largely outdated today, AU files are still supported by many open-source players and audio editors. They’re mostly found in old software archives and educational materials.

How to open AU files

AU files are supported by players like Audacity, VLC, and GoldWave. They're also readable by older UNIX-based systems and open-source software.

If you need a more universal format, convert AU to MP3 or WAV using AnyConv.
