Director of sound (Just like DP or production designer)
Plan from the start (write with sound on mind)
Marry objective with subjective sound so as to create the most evocative possible experience for the audience
How? Give characters the inclination to listen to the world around them
Let each location really come to life from the point of view of the sound
Create a sound plan; just as you create a visual plan
Graph your sound design
Work against the 100% rule. Don't have all your audio tracks at 100 percent, or the sounds will not blend.
