A beamforming technique for rendering multi-channel from recordings obtained using a closely spaced microphone group (cardioids in free space, or omnis mounted on a sphere) is presented. The method allows for optimising the polar characteristics of the group to correspond to the loudspeaker arrangement used, and to obtain the desired panning characteristics.
