I don't know if I'm the only one, but has anyone thought that perhaps
the OP wanted to do this 'just because'? Personally, I think it would be
quite 'cool' to be able to convert a stream of audio into a stream of
integers corresponding to the waveform of the original source. Not to
compress it, not to convert it back, and not to get a unique value. Just
to do it. But then, that's just me. I can't pretend to know what the OP
truly had in mind. :)
