I reminds me of something I read some years ago about someone trying to extract sound from ancient clay pots. The theory being, like a primitive phonograph, sound impressions might had been laid down while on the potters wheel.

I think it all came to naught, but I remember thinking, “How incredible would that be if something – either natural or unnatural – totally unbeknownst to the people or creatures around was somehow laying down sound and that someday, some clever person would be able to extract little audio vingnettes!”

It could be a whole new branch of archaeology. Probably the closest we’d ever get to time travel.

So, when (and if) they can refine their software to the point they can take that phonautogram and reconstruct the sound into something recognizable… who knows what might be possible.
