Audio Files
The 'Audio Files' File Type list includes compressed and uncompressed audio formats, which contain waveform data that can be played with audio playback software. This category also includes MIDI files, musical scores, and audio project files, which typically do not contain audio data.
Common audio file extensions include .WAV, .AIF, .MP3, and .MID.
