Abstract
In this paper, we discuss the application of speech dereverberation techniques for post-processing of recordings taken in the German parliament. Based on a novel psychoacoustically-motivated dereverberation concept, a significant improvement in terms of the perceived quality is obtained in comparison to a conventional dereverberation approach. Since time-varying changes of the acoustical environment are negligible, all required acoustical parameters such as reverberation time (RT) and direct-to-reverberant- energy ratio (DRR), are determined in an off-line procedure.

Bundestag_Merkel_moderate.avi
Video where only the region from 7.5s to 18s is enhanced with the new algorithm (moderate setting)
Bundestag_Merkel_strong.avi

All files are processed at a sampling frequency of 32kHz and stored
after resampling at 48kHz.
