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