Development of Ambisonic Microphone Design Tools—Part 1

Authors: Middlicott, Charles; Wiggins, Bruce

AES Convention 145 · Paper 489 · October 2018

Abstract

In recent years an increase in the capture and production of ambisonic material has occurred as a result of companies such as YouTube and Facebook utilizing ambisonics for spatial audio playback. There is now a greater need for affordable higher order microphone arrays. This work details the development of a set of tools that can be used to simulate and evaluate such microphone arrays, The “Ambisonic Array Design Tool” for simulation and “Ambisonic Array Evaluation Tool” for evaluation. The microphone capsules’ position and directivity can be changed, with the effects on the synthesized spherical harmonics frequency and polar responses observed within the GUI. These scripts written in MatLab have been packaged within a GUI and will be available online.
