  GSM digital audio format
  Developed in Europe, this format was designed for mobile users. GSM is used for audio files that contain a large amount of audio information. Suitable for voice recordings, including recordings of phone calls. You can compress and archive a GSM file to achieve a different file size. The format is mostly used to create and store voice information. There are 4 types of this format that can be opened using different applications.
  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.
