Dereverberation research is expanding, yet no consensus exists on evaluation tools, and psychoacoustic considerations remain underexplored. The study introduces the Multichannel Acoustic Reverberation Database at York (MARDY) to provide real measured multichannel room impulse responses. MARDY comprises real measured multichannel room impulse responses that enable systematic evaluation of dereverberation algorithms. Using MARDY, the authors evaluated three recent multichannel dereverberation methods, demonstrating its practical utility.
Dereverberation is a growing area of research with many new algorithms appearing in the literature. However, there are still no unanimously accepted tools for evaluation of these algorithms. In this paper, we introduce the Multichannel Acoustic Reverberation Database at York (MARDY) containing real measured multichannel room impulse responses. We demonstrate its use for the evaluation of dereverberation algorithms using three recent multichannel methods. Furthermore, psychoacoustic issues regarding the performance evaluation of dereverberation algorithms are discussed.
