About

wowmp3 explains the technical side of digital audio: how lossy and lossless formats differ, how much bitrate is actually worth using, where the loudness difference between tracks comes from, and how to work out a file size in advance.

We do not host audio files and we do not offer downloads. There is no catalogue of anyone's releases here either — with the word mp3 in the domain name it is worth saying so plainly, so that nobody wastes their time.

Everything here is explanation plus a size calculator. Its figures come from a formula rather than a lookup table: bitrate multiplied by duration, divided by eight.
