    au
    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.
    m4a
    M4A, which is short for MPEG-4
    Developed by Apple in 2004, M4A is an audio file created in a multimedia format. It is used to store compressed video and audio files. Worth noting, M4A files can also store images. Using different codecs, you can compress the file with or without losses. M4A is an improved version of the mp3 format. You can convert it to other formats without any loss of quality and size. Playable on devices powered by any Apple platform.
