Sound Localization

INTRODUCTION We constructed a triangular arrangement of microphones to localize the direction an arbitrary sound is coming from. By recording input from the three microphones, we can cross-correlate the recordings to identify the time delay between the audio recordings. Since the physical placement of the three microphones are known, the direction of the sound can

ECE 4760: Final Project Report

Introduction For our final project we made a digital vocoder, which could be accomplished over this semester’s remote desktop environment. A vocoder is a synthesizer that generates sounds which are modulated by an input signal. It was originally designed to reduce the bandwidth of voice signals over the telephone, but was never introduced practically. It
