First Sounds

"First Sounds strives to make humanity's earliest sound recordings available to all people for all time.
Humanity's earliest sound recordings constitute a rich sonic heritage of inestimable value to historians of technology, media, and expressive culture. They are among the rarest and least accessible recordings in our audio legacy. When held by institutions for which they are not the primary focus, many go unrecognized by their curators as sound recordings. And even when correctly catalogued, they commonly remain unpreserved and inaccessible due to a lack of funding or expertise".
