Back in the days I made a small study on audio compression. It’s far from scientific quality, but I nonetheless want to post it, so here we go. (I have edited out some of the blatant errors I have found.)
Introduction
Motivation
Sound is usually compressed in order to save space. Audio space conservation is an important issue in transmission and storage. We may for example want to store audio in such vast amounts that without compression it would take way too much storage space. We might also want to transmit audio data over transmission path having only limited capacity, for example receive a MP3 file through slow modem connection. There are also other constraints regarding compression, much of which is discussed later.
