Joint time-domain reshaping and frequency-domain equalization of room impulse responses

R. Mazur, A. Mertins, Ole Jungmann


In listening room compensation, the aim is to compensate for the degradations that are rendered to an audio signal by transmission in a closed room. Due to multiple reflections of the soundwaves, the listener receives a superposition of delayed and attenuated versions of the source signal. A filter is designed so that the convolution of the room impulse response and the equalizer contains better acoustic properties than the original acoustic channel. Common approaches for derever-beration optimize only the time-domain representation of the overall impulse response and may introduce distortions in the frequency domain. Equalization of the frequency response, on the other hand, often does not consider the time-domain behavior in an ideal way. In this paper, we propose a novel method to jointly consider both the time- and frequency-domain behavior. It outperforms the methods known from literature in terms of dereverberation and equalization performance. Results are presented for a room impulse response measured in a real living room.
