> As previously stated, the MP3 codec was refined using listening tests designed by european audio engineers and featuring the music they chose. In a sense, each of these songs acts as a resonant filter for every file encoded in the MP3 format. Tom's Diner by Suzanne Vega, Fast Car by Tracy Chapman, a Haydn Trumpet concerto... these songs carved out the space of sounds that could be successfully encoded as MP3's.
Does anyone have a full list of the recordings they used for these listening tests?
