Explanation:

A file type can be defined as the standard used to store digital data such as pictures, texts, videos, and audios. They all have unique file extension which determines the type of software program (application) to be used for opening a particular file and accessing its data e.g pictures (jpeg, png), texts (txt, docx, rtf), videos (mp4, 3gp, avi), audios (mp3, acc).

Sometimes, computer users make the mistake of opening files with the wrong software application or program, this often leads to an error due to the incompatibility of the software application with the particular file.

For audio file types, these are some of the commonly used file extensions;

1. AVI: Supports multiple coding of raw data. AVI is an acronym for audio video interleave and it was developed by Microsoft Inc.

2. WAV: Standard audio format supported by Windows PCs. It is an acronym for Waveform Audio File Format developed by Microsoft inc. and IBM.

3. AU: Standard audio format used by Sun, Unix, and Java.

4. MP3: Most popular format when downloading music.

5. RA: Real audio.

6. AIFF: Standard audio file for Macs
