Only two
values are enough to mathematically reproduce
an exact waveform; even more precise than you can sample it.
Like vector graphics! So if that's the case say, why do we still have
MP3? Why don't we just convert whatever sound files we have into
mathematical formulae and have players to convert them to sound at any
sampling rate?

Also audible as an mp3 at:

(It's one of the songs, just press the download link above the formula)
A bit OT though, as it's made with Goldwave in windows
