Deciphered the sound cloud file:
T I A UD T DIMCIATDRL 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 VEN EU
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.
In the beginning it says DIMCIATDRAI. If you take every second letter starting from the first you get, DMITRI with the left over words ICADA. Does anybody know what it means?
Hmm, I am guessing it refers to CICADA 3301 ---> K
3R
3Y
0P
1T
But why would it refer to CICADA 3301 Games?
Beat you by about a minute and a half.
Actually, I saw the 3301 and suspected this awhile ago, but the ICADA comment above clinched it for me. No clue what it means though.
Rail fence 5 of DIMCIATDRL = DMITRICADL of K3R3Y0P1T = 3301KRYPT
Now how do we decrypt T I A UD T VEN EU
