Abstract: Aspects of the subject technology provide improved point-to-point audio communications based on human variable sensitivity to latency differences in multipath communications. In aspects, improved techniques may include measuring a level of ambient noise, and then selecting processing for a received electronic audio based on the measured level of ambient noise before emitting the processed audio signal at a loudspeaker worn by a listener.

Abstract: A multi-radius spherical microphone that includes an inner body defining an inner sphere having an inner radius from a center; a plurality of inner microphones coupled to the inner spherical body and defining an array of inner microphones; an outer body defining an dodecahedron, wherein the inner body and the outer body are concentric about the center; and a plurality of outer microphones coupled to the outer body at respective vertices of the dodecahedron and defining an array of outer microphones, wherein each of the plurality of outer microphones is positioned radially equidistant from the center.
