The Ghost in the mp3

Neat article about audio compression.

This guy isolates the audio [and video!] lost in compression to mp3.

Apparently Tom's Diner by Suzanne Vega was one of the reference songs used to test mp3 compression. 

The MPEG-1 or MPEG-2 Layer III standard, more commonly referred to as MP3, has become a nearly ubiquitous digital audio file format. First published in 1993, this codec implements a lossy compression algorithm based on a perceptual model of human hearing. Listening tests, primarily designed by and for western-european men, and using the music they liked, were used to refine the encoder.

Nice comment about equity too!
