Deciphered the sound cloud file:

I translate it to:
"DIMCIATDRAI THERE ARE MORE THAN 30 BRAINWALLETS. YOU CAN FIND THE 31ST BRAINWALLET WHERE IT ALL STARTED. IN THE STARTOF THE THE BEGINNING. STARTS WITH PAPA END WITH MIKE. K3R3Y0P1T"
With errors (typos?) and everything.
Starts with papa (p) ends with mike (m).
Satoshi's paper started it all.
Peer-to-Peer Electronic Cash System
Interesting, but you are not quite right. The title of the whitepaper was: "Bitcoin: A Peer-to-Peer Electronic Cash System". See https://bitcoin.org/bitcoin.pdf.
Also, Satoshis first email to the cryptography mailing list had the subject: "Bitcoin P2P e-cash paper". See https://www.mail-archive.com/cryptography@metzdowd.com/msg09959.html
It seems you are onto something with the NATO alphabet, though.
Unfortunately, I do not have time to play with this again
It's a shame coz it just started to get more interesting.
None the less I will leave this here for you guys to have fun with:
31ST BRAINWALLET WHERE IT ALL STARTED. IN THE STARTOF THE THE BEGINNING. STARTS WITH PAPA END WITH MIKE.
