Safe and sound

Bitcoin has a bit of James Bond flair to it. Encryption, secret keys, anonymity and the ability to send money around the world instantly as part of a growing shadow economy is all good fun.

But Sound Wallet takes this latent spy esthetic to a delightfully extreme new level by taking a BIP38 encrypted key and converting it into a sound file which, to the casual listener, will just sound like static. Listen to that sound with an app called AndroSpectro (or Audacity with the right settings), though, and out of the static emerge the characters that comprise the encrypted key.

But that wasn’t extreme enough for bitcointalk user krach. Sure, you can have him email you the .wav file, or burn it onto a CD, but you can also have him cut it into a 7″ vinyl record.

And that is unbelievably groovy.

The resulting record is clear, with edges that are just a bit rough. The card that came with it explains:

“This record was hand shaped and individually cut in real time using a vintage 1940s Presto 75A recording lathe. It is a unique piece. It is not the same as a traditional pressed record. It was not made in a factory. It was hand carved from an 8ft sheet of polycarbonate plastic, shaped, sanded, waxed and cut in real time by one person.”

The burst of gentle static at the beginning of the record contains the key, but then the recording transitions smoothly into some harsh electronic music. This is a great touch, as anyone snooping through your record collection will think it’s just an obscure recording.

This is such a fun object. It would be a great way to hide a key in plain sight, certainly, but it’s also such an elaborately conceived and constructed wallet that it feels like a piece of art.
