The idea of the preservation of the voices stems from human curiosity. One of the things that struck me about this article was how the phonograph seemingly made a bunch of adults into giddy children. On top of this, as humans do, this group tested and experimented with the device. For these people, these are their first ever experiences with recorded sound. The appeal behind hearing their voices perfectly recorded comes from their curiosity of the limits of the device. Today is no different, humans want to hear sound as if someone were next to them speaking into their ear. But those practices have also evolved today. Humans have moved from wanting to perfect the recording of their voice to wanting to perfect the manipulation of their voices. Things like reverb and echo and auto-tune have altered the way humans can communicate in recorded sound. This has ended up exceeding humans actual ability to speak. Recorded sound can now be produced in a way that could never have been done before. And we now see this production being applied to live concerts as well through the use of amps and sound boards. I’m sure Edison never imagined this is where the phonograph would go.
