Here is an example of some sound design and dubbing, the music on this is not my own but some royalty free purchased by the end client.
However I think it works amazing well building up the suspense.
This clip uses a lot of Doppler effects to mimic travel as well as a lot of foley for movement, a few stock sounds and effects for mimic environments.
Another Example of sound design this time to make it hyper real is this rollercoaster.
This video shows the diffrence between the location i.e the real sound and the hyper real sound design. In this video everything from skateboards, wind noise, deep rummble, hydrolic presses and heavey machineary where used to create a sound the listener might expect from a roller coaster.
