What is an AU file?
Developed by Audacity, its cross-platform audio editor by the same name uses the AU extension. The format belongs to the audio files category and stores binary data. These are header-less one-channel PCM audio with sample rates and bit rates defined in a lateral AUP file.
The software automatically converts any imported audio data into AU and stores it in a specific folder. The user can export the edited files in any of the more popular formats such as WAV, MP3, and others.
