Definition

A surround sound method that combines binaural audio reproduction methods with ambisonic surround sound technology.

Introduction

Virtual ambisonics is a method that combines binaural audio simulation and the surround sound reproduction method known as ambisonics. This entry gives an overview of the basic psychoacoustic theories behind binaural hearing, methods to simulate binaural hearing, and the issues that may arise from these simulation methods. This is followed by a brief description of ambisonics and how it can be combined with binaural audio to create virtual ambisonics.

Binaural Hearing

Binaural hearing describes how humans are able to locate a sound source in three dimensions using two ears. A listener can identify sound sources based on the difference between the time of arrival (interaural time differences or IDT) (Wightman and Kistler 1992) or the difference in intensity levels (interaural level difference or ILD) (Hartmann...
