Insert – technology

I am not going to lie, I have been having a bit of a mental block this morning, creatively (ha!) I have had no idea what to write.  Luckily – insert technology. I saw this posted last week, but didn’t really get a chance to read it… but I did today and it’s pretty awesome.

The Smithsonian Institute was able to recover a voice recording from Alexander Graham Bell (yes, that one) which was made in 1855! The audio was originally recorded on a cardboard disc coated with wax. The grooves on the wax, similar to those on a vinyl record, were recovered using high-resolution digital imaging.

Researchers at the Lawrence Berkeley National Laboratory created a map of the disc, then processed the image to remove any marks or damage that could cause skips or scratches during playback. A computer then calculated the sounds that would have been played back by a stylus moving through the grooves.

You can listen to the recording either here on Wired or here on CBC

How cool is that?!
