Zusammenfassung: Higher-order Ambisonics recordings obtained from a single spherical microphone array inherently allow for immersive reproduction with all three rotational degrees of freedom (3DoF). On the other hand, physically correct implementation of user movement in the additional translational degrees of freedom is possible within a narrow range only. Therefore, a key technology to advance to 3DoF+ or 6DoF are sound field translation methods, which omit physically correct reconstruction in favor of psychoacoustic plausibility. In this work, we review recent advances in the field and juxtapose adaptive and non-adaptive methods. Relevant properties of different methods are compared using a novel visualization scheme. We complete this work with a discussion of limitations and opportunities of the approaches.
