The music is the 20th anniversary release of Soundgarden’s Superunknown album from 1994. You can listen to album samples by downloading the free app at the iTunes store. The idea behind the DTS Headphone: X format is to let you listen as a producer would.
I gave the new mix a listen via the app that is available today. I used the Beyerdynamic headphones I just completed a review of, and the sound really was terrific. The app lets you select the way you are listening; ear buds, over ear, on ear headphones, or speakers. You can hear the spatial cues move with each setting. I didn’t have the plain old 2 channel mix to compare, but the sounds of the DTS 11.1 channel mix did seem to be quite different than standard headphone listening. Rather than hear the music “in my head,” there were instruments in front of me, and arrayed to the sides and behind me. I also felt some instruments originated above me. I thought the DTS 11.1 mix did a good job of sounding likes I was listening to speakers with the instruments in real space. I’d love to hear more music released this way, as hard rock is not always the best way to judge sound quality. I’d prefer to hear some acoustic instruments to really judge the effect.
