An Impulse Response Dataset for Dynamic Data-Based Auralization of Advanced Sound Systems

This engineering brief presents a freely-available binaural room impulse response (BRIR) dataset measured on a multichannel loudspeaker system. The 32-loudspeaker array includes all loudspeaker layouts specified in Recommendation ITU-R BS.2051. Measurements were carried out in an ITU-R BS.1116-compliant listening room using a Neumann KU100 dummy head microphone. BRIRs were measured at 2° steps of rotation of the dummy head. The dataset can be used for dynamic data-based auralization of multichannel loudspeaker signals, such as those generated by the so-called advanced sound systems described in ITU-R BS.2051, i.e., systems that can render surround sound with height signals from channel-based, object-based, and/or scene-based content representations. The dataset is made freely-available in the SOFA file format.
