Knowing more information about the AU format will help you understand the reason why it is necessary to convert AU to MP3. An AU file is an audio file created with the open-source, free Audacity audio editor.

The audio file is kept in a format that only Audacity audio software uses. Projects created using Audacity include AU files, which are saved as AUP files. It is not recommended to open AU files individually. Open the Audacity (cross-platform) project that utilizes your AU file instead.

AU files can also refer to other types of audio files. Java software can play a digital audio file format from Sun that is utilized on the Internet. It utilizes the .au extension and offers toll-quality sound. It often employs the u-Law (mu-Law) encoding technique. The only difference between raw u-Law files and AU files is the file header.
