SECRET MESSAGE on HadoukenCabs.com?

Okay so, we all know that hadouken cabs video and website, as well as the PS4 commercial that had Ryu in it for a few seconds.
http://www.hadoukencabs.com
Anyways, I found the URL for the inaccessible audio file that plays on the Hadouken Cabs site.
http://www.hadoukencabs.com/audiofile.mp3
I imported the audio file into audacity and, there’s some mighty suspicious static at the end. I know the static isn’t an importing glitch because if you just play the audiofile at its URL in Google Chrome the static is still there. Almost exactly 0.65 seconds of it. It just comes out of nowhere at full volume then the audiofile ends.

I’m GUESSING that there’s some hidden message in the static, but there might be one in a different part of the audio file instead. Can you guys start scanning this audiofile with your audio analysis machines or something? Please? It just seems so strange that this teaser gets released and then NOTHING. there might be some kind of ARG aspect to this Hadoken Cabs thing!
