Practical Recording Techniques for Music Production with Six-Degrees of Freedom Virtual Reality

摘要

This paper presents practical spatial audio recording techniques for capturing live music performances for reproduction in a six-degrees of freedom (6DOF) virtual reality (VR) framework. The end-goal is to give the listener the ability to move close to or even around musical sources with a high degree of plausibility to match the visuals. The recording workflow facilitates three major rendering schemes - object-based using spot microphones and diffuse field capture microphone arrays, Ambisonics with multiple-placed sound-field microphones and hybrid approaches that utilise the prior two methods. The work is presented as a case-study where a jazz ensemble is recorded at Studio 3 of Abbey Road Studios London using the proposed techniques.
