The audio looks like an anagram.
In the end, the only thing I interpreted was the front.
in that part
"set... s...hado nom (shadow anomaly) for ligh...t open me uaually airft in a cof"
Like "shadow" and "nom," I think "airft" and "in a cof" are pronounced as they seem.
I think the important part is "set shadow nom for light"
This is the best interpretation for me because English is not the first language.
I just want the producer to reveal the secret.
I was under too much stress because of the game.
