Much chatter lately about http://www.firstsounds.org/:
First Sounds is an informal collaborative of audio historians, recording engineers, sound archivists, scientists, other individuals, and organizations who aim to make mankind's earliest sound recordings available to all people for all time.
I downloaded some of their mp3 files & played them; the Au Clair de la Lune recording was barely recognizable as a human voice, but the Metropolitan Elevated Railroad recording was just static overlaid with random wah-wah effects.
Perhaps my hearing just isn't good enough to appreciate such things.
