1. A system comprising:
at least one room impulse that includes one of Binaural Room Impulse Response (BRIR) data or Binaural Room Transfer Function (BRTF) data for a target room; and
filters comprising transfer functions to convert a BRIR for a first reference position to a BRIR for a second reference position,
wherein the filters are combined with the at least one room impulse to generate a BRIR for a second group of virtual speaker locations.
