An audio format is a medium for sound recording and reproduction. The term is applied to both the physical recording media and the recording formats of the audio content —in computer science it is often limited to the audio file format , but its wider use usually refers to the physical method used to store the data.

The compact disc almost totally dominated the consumer audio market by the end of the 20th century, but within another decade, rapid developments in computing technology saw it rendered virtually redundant in just a few years by the most significant new invention in the history of audio recording — the digital audio file (.wav, .mp3 and other ...
