Check out this “Inception” Sound for Film Profile and learn how all the intricate sounds were created and matched to the mind-bending action that takes place on the screen.  Sound designer Richard King, re-recording mixer Lora Hirschberg, and re-recording mixer Gary Rizzo try their best to explain things as rudamentary as possible.  It’s an interesting watch.  (…But I still want to know where the “burrr” comes from.  Maybe it’s here.)
