Stego 13 - hear the answer

Hi! My trouble is that I exactly know how I should edit the file, but I can't get the password in the right way. I was playing with rates to make the file more easily understandable. I know it begins with "The password is", but … I get stucked on pw part. I tried a tons of combination with lower and uppercase letters too, but nothing worked. Is there anyone who can help me? :(

Try to play with the tone. Increase or decrease the frequency then you should hear it in a more human voice. Try audacity for example. The effect tools should be helpful. Also, the password is case sensitive ;)

hint I think there are aliens and uFo's in area 51 lolZ hint

btw…your signature rocks…the person who made it for you must be awesome! xD

Anyway…I hope I put you in the right direction. :)

Finally I got it. Thanks for the help.

I hope this won't be a big spoiler: The pw doesn't start with a number. :D
