Both the quality and immersion of binaural auralization benefit from head movements and individual measurements. However, measurements of binaural room impulse responses (BRIRs) for various head rotations are both time consuming and costly. Hence for efficient BRIR synthesis, a separate measurement of the listener-dependent part (head-related impulse responses, HRIR) and the room-dependent part (RIR) is desirable. The room-dependent part can be measured with compact first-order microphone arrays, however the inherent spatial resolution is often not satisfying. Our contribution presents an approach to enhance the spatial resolution using the spatial decomposition method in order to synthesize high-resolution BRIRs that facilitate easy application of arbitrary HRIRs and incorporation of head movements. Finally, the synthesized BRIRs are compared to measured BRIRs.
