Tetrahedral Microphones: An Effective A/B Main System

Authors: Dobson, Alexander; Woszczyk, Wieslaw

AES Convention 147 · Paper 554 · October 2019

Abstract

A simple approach to produce an effective stereo main audio recording system using tetrahedral microphones is described, capturing a full array of close and distant sound with a substantial amount of early reflections. This allows for the easy possibility of later surround or 3D reproduction. Furthermore, the implementation of a pragmatic and simple two-microphone set-up can lead to an efficient capture of the stereo soundfield that has many applications. Particular attention was paid to binaural mixing of this microphone system to demonstrate an easy first step into immersive reproduction of the sound.
