    AU format for reliable data storage
    This audio format was developed by Sun Microsystems. It is intended for storing audio files; the file itself consists of three components: the header, the annotation unit, and the audio file itself. What distinguishes this format is the small file size, due to which its sound quality is low. It can be converted into other formats, such as mp3 or MPEG. Although this format is mostly used on personal computers that are powered by operating systems Sun or Unix, AU files can also be opened using other audio players.
    mp3
    MP3 (more specifically, MPEG-1/2/2.5 Layer 3; but not MPEG-3)
    A standardized file for storing audio information. Supported by virtually all music players and playable on almost all mobile devices. When the audio data is compressed, the sound quality decreases, albeit insignificantly. The compression process erases the frequency that is imperceivable to the human ear. This format allows you to save storage space. You can store and send the audio files after compression. The MP3 format was developed by the German company Fraunhofer IIS. The user can adjust the compression ratio and the audio file quality.
