1. A method for spatial audio reproduction based on directional room impulse responses, the method being performed by a processor that executes at least one instruction stored in memory, the method comprising:
selecting measurement points around a listener based on a location of the listener;
calculating a directional room impulse response (D-RIR) for the location of the listener based on directional room impulse responses (D-RIRs) for the measurement points around the listener; and
reproducing spatial audio at the location of the listener based on the D-RIR at the location of the listener.
