Rage!

Difficulty: Easy

Statement: A raging Real Wild Child!

Flag is the STRING you end up with after solving challenge, case insensitive.

The challenge provide the file rage.wav

The value of the recovered Morse code:

.-. .- --. .. -. --. - --- .-- . .. .-. -.. .-.. .. -... .. -.. ---

I will use this website to decode it and get the flag.
