Development of ambisonic microphone design tools – Part 1.

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 utilising 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 which 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 synthesised 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.
