> 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 Was thinking in the shower just the other day about genre-specific compression schemes. Could you get significant improvement if you knew something like the BPM or the spectral profile of common instruments ahead of time? Or is production too inherently complex for this to be worthwhile? Obviously no two hurdy gurdy recordings will sound the same, even though your algorithm knows wtf a hurdy gurdy is.
