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 [1] and the presented part is available for demonstration purposes. More details can be found in the conference paper [1]. The single-channel test data were generated from the acoustic material recorded by the microphone array using the MAPL software processing library [2].

In case of using the provided test set for your research, please cite the following references.
