Evaluation of Speech Dereverberation Algorithms Using the Mardy Database

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.
