Abstract
The purpose of room impulse response reshaping is toreduce reverberation and thus to improve the perceivedquality of the received signal by prefiltering the sourcesignal before it is played with a loudspeaker. The opti-mization of an infinity- and/orp-norm based objectivefunction in the time domain has shown to be quite effec-tive compared to least-squares methods. Multi-positionapproaches have been developed in order to increase therobustness against small movements of the listener. Ithas been shown recently, that it is necessary to alsoconsider the frequency-domain representation of the re-shaped impulse response, in order to avoid spectral dis-tortions of the overall system. In this contribution wepropose to jointly optimize ap-norm based criterion inthe time and frequency domains for multiple positions inorder to achieve a good reshaping while not affecting theperceived quality due to spectral distortions in a limitedlistening area.
