I was just listening to Sensucht by Rammstein on my Dolby Pro Logic sound setup in the front room. What I don't understand is how my CD has surround information encoded on it. Listening to certain songs, there are at least three discreet channels: right, center, and left. I can understand the receiver extrapolating or just mirroring the front and creating the rear channels, but where does it get the center channel information? Well, however it does it, it sounded damn cool!
