Thanks to the tireless efforts of the Hogalum Museum, an extraordinary
recording has been unearthed, restored, and digitized for distribution
via the internet. The recording is a copy of an 1874 test of the
Electro-Auto-Acousti-Graph-o-Matic conducted by Phineas Magnetron, and
is the earliest known recording of its kind. The estate of Thomas A. Edison has refused comment.
