I see where you're coming from but here's why it's not true
Weird, it's still working for me. Just so it's clear, the password is "Nibble" and the link I'm using is https://cryptpad.fr/file/#/2/file/-LpBxk3ZcshQMwk3C-aARA64/p/
I guess I could upload the mp3 for you elsewhere, but since this is some ARG that'd probably defeat the point?
Anyway, I might check out the mp3 file a bit more when I have time this weekend. I did raise the pitch and speed a bit in Audacity, but I didn't hear anything more interesting. Audio forensics isn't my specialty, so maybe I just have to try harder or something lol
u/Depressed-Toad those numbers come from the image in this post: https://cryptpad.fr/pad/#/2/pad/view/AsP+WY-omRlPQFt7+zvqYrLSmK9rQtcKX+WNn3j5L8Y/embed/ where the binary at the bottom asks us: Who took this photo.
So looking at the exif data gives us those numbers as the creator of the photo.
