All any file is is just numbers. Opening a file in a program is just interpreting those numbers. To over-simplify, in a plain text file, for example, the number 32 means “space character”, and the number 10 means “move down to a new line”. In an audio file, the numbers are going to have meaning related to volume and frequency of sound, at points in time.
