The interpolation of binaural room impulse responses (BRIRs) is a very common technique in the field of immersive audio rendering because it aims at reducing the responses measurements guaranteeing a correct sound spatialization. These approaches are usually based on the interpolation of the responses starting from the division in early reflections and reverberant tail considering a fixed arbitrary mixing time. However, this aspect could influence the interpolation methodology when real BRIRs are considered. In this paper, a state-of-the-art interpolation algorithm is improved adding an automatic procedure for the calculation of the exact mixing time and applied it to a set of BRIRs, measured in a real reverberant environment. Several experiments have proved the effectiveness of the proposed approach.
