In this paper we introduce the "Edge Fading Amplitude Panning" (EFAP) method for 3D loudspeaker setups. Similar to other panning methods like Vector Base Amplitude Panning (VBAP), it can be used to create phantom sources between the loudspeaker positions. The proposed method features symmetric panning gains for symmetric loudspeaker setups, N-wise panning by using polygons instead of triangles, and a better behavior for large opening angles between loudspeakers while involving a computational complexity that is in the same order of magnitude as VBAP.
