This dataset includes 720 directional B-format RIRs, i.e. first-order Ambisonic room impulse responses, measured at 30 receiver positions with 1m spacing in an equidistant grid (4xm) with 24 hemispherical source positions each. The measurements were carried out at the IEM CUBE using Soundfield ST450 MKII microphones. The data is saved according to the SOFA convention (https://www.sofaconventions.org/mediawiki/index.php). The SOFA Matlab/Octave API is available at https://github.com/sofacoustics/API_MO.5. Unfortunately, the used SOFA convention (MultiPerspectiveAmbisonicRIR) was never integrated into the official SOFA conventions. However, it can be found at: https://github.com/jdemuynke/API_MO/tree/master/API_MO/conventions.
