This paper describes a strategy for recording sound and enabling six-degrees-of-freedom (6DoF) playback making use of multiple simultaneous and synchronized higher-order ambisonics (HOA) recordings. For the evaluation of the proposed approach a 3D audio-visual navigable playback system was implemented. Subjective listening tests were conducted presenting three distinct scenarios, one using spatialized mono sources and the other two interpolated listening points from 1st and 3rd order multiple ambisonics sound fields. The obtained results demonstrate that HOA recordings are suitable for reproduction of 6DoF immersive audio scenes.
