Effects of Capsule Coincidence in FOA Using MEMS: Objective Experiment

This paper describes an experiment attempting to determine the effects of capsule coincidence in First Order Ambisonic (FOA) capture. While the spatial audio technique of ambisonics has been widely researched, it continues to grow in interest with the proliferation of AR and VR devices and services. Specifically, this paper attempts to determine whether the increased capsule coincidence afforded by Micro-Electronic Mechanical Systems (MEMS) capsules can help increase the impression of realism in spatial audio recordings via objective and subjective analysis. This is the first of a two-part paper.
