Comparisons of four processed versions of the ART method (P1, P2, P3, P4) with the reference (Ref) and the unprocessed (UnP) BRIRs in Room1. The two upper panels show the ATFs of BRIRs for Ref, UnP and processed BRIRs for the right and left ears. The lower-left panel illustrates the Interaural Coherence (IC) of the processed and UnP cases, along with their comparison to the reference BRIR for perceptually relevant frequencies below 1500 Hz. The lower-right panel shows the Schroeder energy decay curves (EDCs) of the BRIRs.
