At this point, we've gone over all the basic methods of audio: stereophonic 2D, spatialized stereophonic 3D, and realistic HRTF 3D audio. With that foundational understanding, we'll use this section to add several more audio effects to the scene to make it seem truly complete and cohesive.
Footstep sounds are pretty common in shooters, especially shooters that don't have a radar mechanic. It's a great, subtle way to hear an enemy around a corner, and the more accurate the localization is, the more the sound becomes a useful part of the environment instead of just a noisy effect.
In this section, we'll create a footstep mechanic for the players in the game, and we'll use HRTF audio with reflections to create a realistic effect.
Drag the Footstep1.wav and Footstep2.wav files that were included with this chapter into your Audio folder. Create a new empty GameObject, name it FootAnchor, and make it a child of the OVRCameraRig so it sticks...
