Solutions: The Hex Factor v2010 (Level D100)

When you listen to the MP3 file, you're bound to recognize Morse code, even if you can't understand it. Morse code is so universal that everybody recognizes it.

Decoding Morse code is not difficult, but it can be tedious if you have to do it manually. One way is to open the MP3 file in Audacity:

The Morse code of this challenge decodes as
"The password is 71401"

Or you can try to decode it with a program, like this one.
