An innovative method for binaural room impulse responses interpolation

The interpolation of room acoustic impulse responses is a widespread technique that allows to reduce measurement sets. In this paper, an innovative method for Binaural Room Impulse Responses (BRIRs) interpolation is presented and tested. In the proposed method, the BRIRs are decomposed in time and then divided in two frequency bands and an innovative peak detection and matching algorithm is applied for the early reflections, combined with a linear interpolation. A real room binaural impulse responses database has been employed in order to evaluate the algorithm comparing it with the state of the art. Experimental results have proved the effectiveness of the proposed approach
