Dinosaur9.wav - Portal

"dinosaur9.wav - Portal" is a high quality rip of "dinosaur9.wav" from Portal.

Joke
The original track is an SSTV image which was part of the Portal ARG. This rip encodes the following image:This is the Konami logo with the number nine (in the same font) placed next to it. At the top-left and bottom-right, we see the Aperture Science logo and the text "12 & 13/19", respectively, which are references to the original ARG. The 9 alludes to how the number 573 could be pronounced as Konami in Japanese (5 is Ko, 7 is Na, and 3 is Mi, so 573 is Konami) giving us the values  at positions 12 & 13 for the hex string that leads to "cam_apsci_1532.avi".
