New Paper: Localisation with Third Order Ambisonics and Off-Centre Listeners

Last month the last paper from work done during my thesis was published in the Journal of the Audio Engineering Society. We tested localisation for off-centre listeners with third order Ambisonics for two different noise signals: transient and non-transient. We found, in line with Precedence Effect literature, that the transient signal produced sound images pulled more towards the nearer loudspeakers than the non-transient signal.

We also tested different localisation models. All of them were relatively good at predicting the perceptual results. The best results were obtained by an extended version of Gerzon’s energy vector that includes elements of localisation dominances and the precedence effect (See here for an overview and here for the paper).
