Really interesting article. Unfortunately it looks like media preservation only goes so far: I'm getting 404s for all of the embedded audio files.

I like the suggestion from 1890 to use cotton in the ears as a low pass filter to increase fidelity.

While the author used software to retrieve the sound, I bet it could be done with photochemical methods onto a copper disk, similar to how circuit boards are etched.

Or how soundtracks are photographed onto movie film.

I never thought about this until your comment. Fascinating!

I'm blown away by the complexity of sound that can be conveyed in what seems a simple manner.

[jacquesm → ada1981]

That's because in essence even the most complex sounds change just one environmental variable: local air pressure.

I'm falling in love with sound all over again. Yes, that is obvious now that you say it, but I never realized it before. Thanks!

Excellent work and a great example of how sometimes the best presentation of archival assets is remediation.
