The main 2 goals are to be able to:
1. Cut a record with your private key on it. You can hang it on the wall, put it in a safe or play it at the next party.
2. Do more research and make the audio keys so that you can not hear them, to allow them to be hidden in songs ect (cant do this yet)

Sound Wallet, a private key in audio form cold storage meets sound. The ultimate goal is to cut records which have encrypted private keys on them. You then play the audio and with use of a spectroscope you can see your private key. The private key can be enycrypted using BIP0038 so that if anyone else "hears" your private key it will still be encrypted. You could also have the private key on a CD,Magnetic Tape, or any other virtualy any other audio format. Why? Cold storage is the safest way to secure your crypto coins. For long term cold storage records will last longer than any usb stick, memory card, or ink on a paper wallet. Records are the ultimate archive format. You could add the record to your record crate, put it in a frame and hang it on your wall, or store it in your safe.Where we are at now: We have been able to embed a private key in into audio and then read the private key using a spectroscope app on anandroid phone. The audio is about 30 seconds to one minute of noise for one key. Our vision: To provide a service of embedding private keys into audio.To be able to cut high quality records with the private key in audio form for long term storage.To be able to "hide" the private key in any song. You would only be able to see the private key with a spectroscope.To create our own spectroscope app that is designed for the purposes of reading and saving private keys.What we need:Record Lathe (vinyl recorder)

Private Keys can be encrypted

Feel free to PM me with any questions or ideas

Sounds like a good idea look forward to seeing this.

You're using the frequency domain to encode data right? (Pardon me, not an EE). How much degradation can you take and still produce something remotely readable? And wouldn't something like a bit encoding system that encodes in discrete chunks give something more error tolerant?

I have done tons of tests and you can read the private code letters and numbers. I want to go deeper and go into something like a bit encoding system ect. Right now it is readable and audible.

This is what it looks like when you "read" the sound with the spectrograph android app,
save image and put it in pantbrush or some other program and import your key into a wallet.

You can try it for yourself:
Download this free app for android
https://play.google.com/store/apps/details?id=com.augury.androspectroLite&hl=de
or look for a spectrograph program for your desktop

Then use this sound

also works for altcoins

If you plan on using records, don't they get scratched easily? If you scratch it, or it drops and breaks then you're out of luck, there go your coins. What can you do to combat this?

Hi,
Yes you have to take care of the record. However a scratch would not be a problem, you would still be able to read the key. The idea with the record is meant for long term storage. In the really long term a record will last a lot longer than a usbstick,cd, or memory card.

really cool  :D

Could you embed QR codes instead of the key in plain text?

"Could you embed QR codes instead of the key in plain text?"

I am working on that. ATM I am not able to get the QR readable enough, but I think I am close to fixing that. Then you would have both the QR and plain text.

Guys please support the project by joining startjoin.com and following my project http://startjoin.com/wallet

Thanks

OK
HERE IS 1 mBTC go get it!
Inside the audio is the private key for you to import:

Someone took it:

I fiddled around with Audacity's spectrogram and set it to grayscale, it works.

Stay tuned, I will do some more giveaways. I havent checked if someone already got the maxcoin one.
Ah yea I didnt even try Audacity, thats cool because it is free and easy to use.
AndroSpectro Lite is free but you can only save a picture around 3 times before you need the pay version.

If you send me an encrypted private key I will send back your sound wallet as a .wav file

0.0001 BTC FREE!

What a cool idea! Will test this out.  ;)

This is Awesome!

I am designer/developer or PopularCoin POP!

We would love to have this, is there anything that we can do?

Yes please go to http://startjoin.com and make an account, then follow the project at http://startjoin.com/wallet
I can also do a promotion with your coin, just PM me
I would need some coin for the promotion to give away that I will "hide" in the audio.

looks like someone got the 0.0001 BTC I will make another today!

4 never-funded bitcoin private keys for...

ok the funding didnt work but you got the private keys. Funding coming.

Good idea I will be keeping my eyes on this.

I think you've proven the concept, that private keys can be recorded and viewed by spectrograph consistently.

However, you're just wasting your BTC by sending 0.0001 and less amounts, as the TX fee is exactly the same or more. The only people who gain from dust transactions like these are miners. I won't be spending these keys unless the fee is changed to make me not go into the red.

Hi,
Yes you are right. I might just increace the ammount for the giveaways. Everytime new people try it out and are exposed to the proof of concept.
So who wants to send me an ENCRYPTED private key and then I send you a sound wallet of your own as a .wav? Just to test it out. You can password protect your QT wallet and then create a private key, then I will have the private key but not the password so I wont be able to get the coins that you store in your sound wallet, another option would be to use BIP38 on bitaddress.org , same idea. If you use bitaddress then you might want to use an offline computer or at least disconnect while generating your address. Then you can use the sound wallet just as you would a paper wallet. You can load some coins on it and store it somewhere.


You can send me the private key via PM here
