This was the easiest one.

Load the mp3 in audacity.We can easily notice that the effect was reversed.

Go to Effect->reverse now you can use the morse code if u have observed as soon as you have loaded the file.

This is the morse code extracted : ".. .-.. --- ...- . --. --- .- -.-.-- -. ..- .-.. .-.. -.-. --- -. ..--- ----- .---- ....- .. ... .- .-- . ... --- -- . -.-.-- -.-.--"

after decoding the morse code we get ILOVEGOA!NULLCON2014ISAWESOME!!

FLAG : ILOVEGOA!NULLCON2014ISAWESOME!!
