Chip Idea:
1. Given a microphone and pinna-like structure identify some featureIn the frequency domain that is a reasonably reliable cue for elevation. WriteSome MATLAB code to demonstrate this.
2. Design a neuromorphic circuit that can extract this information and reportan up/down signal to drive an actively pointing microphone.
