Research & Development


This engineering paper 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-RBS.1116-compliant listening room using a Neumann KU100 dummy head microphone. BRIRs were measured at2◦steps of rotation of the dummy head. The dataset can be used for dynamic data-based auralisation 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.
