We managed to recover a FLAC file, but it seems broken. It looks like a few
bits were flipped near the start of the file. Can you fix it and recover the flag?broken.flac 3d506be4434f2f537215a4995e497405

Hint: all Latin characters in the flag are lowercase. You will need to insert the {
, }
, and _
characters back in. As always, _
are only used to separate words.
Hint 2: the flag is exactly 37 characters long.
This problem is from DMOJ Capture The Flag '20. For more details, please view the contest page.
