Curators and scientists worked together to recover the audio recorded on Alexander Graham Bell’s earliest records, recorded at his Washington, D.C., Volta Laboratory. Using 3D cameras, they created depth images of the surface of the records, and reconstructed the wave forms with audio software. This short documentary was produced by Ryan Reed for Smithsonian magazine.
This is incredibly cool. I love when modern technology allows us to gain a deeper understanding of history, and in such a new way. Who would have ever thought we’d be able to hear the audio from these recordings? Unbelievable.
