The provided audio samples represent a freely available selected part (30 segments) of the test set recorded by a multi-channel spherical microphone array in a medium sized, acoustically not optimized room with a relatively long room impulse response (real acoustic environment). The full reverberant test set was used in the experimental evaluation in  and the presented part is available for demonstration purposes. More details can be found in the conference paper . The single-channel test data were generated from the acoustic material recorded by the microphone array using the MAPL software processing library .
