Default [Q] Slow Motion Video's Audio?

After the 4.3 update, the HTC Butterfly s also the real-time audio of a slow-motion video so you can hear it when the video is played at real-time speed on the phone. Does anybody know how I can access this audio file?

When I import the slow-mo video file into Sony Vegas there is nothing else other than the video in slow motion. (From what I recall, you need to download some Quicktime codecs to import the videos into Vegas, they aren't very good and lag on my old computer with the HD video)
HTC Butterfly s 901e
HTC One X+ Telus LTE (screen scratched and dust gets into camera sensor )

Both on stock roms
