Most binaural audio algorithms render the sound image solely on the horizontal plane. Recently, immersive and object-based audio applications like VR and games require control of the sound image position in the height dimension. However, measurements from elevated loudspeakers require a 3D loudspeaker setup. By analyzing early reflections of BRIRs with a fixed elevation, spectral cues for the height perception are extracted and applied to HRTFs. The parametrization of these cues allows the control of height perception. The sound image can be moved to higher as well as lower positions. The performance of this method has been evaluated by means of a listening test.
