There is renewed interest in virtual auditory perception and spatial audio arising from a technological drive toward enhanced perception via mixed-reality systems. Because the various technologies for three-dimensional (3D) sound are so numerous, this tutorial focuses on underlying principles. We consider the rendering of virtual auditory space via both loudspeakers and binaural headphones. We also consider the recording of sound fields and the simulation of virtual auditory space. Special attention is given to areas with the potential for further research and development. We highlight some of the more recent technologies and provide references so that participants can explore issues in more detail.
