Abstract
The term Room in a Room describes an old technique which can be utilized for auralization purposes. Thereby the auralization procedure can be divided into an analysis- and a synthesis task, usually dependent of each other. The analysis recordings in the source room have to be made exactly at those directions where loudspeakers are physically placed in the target room. In doing so, the spatial separation, respectively, filtering will be realized by beamforming. The outputs of the different, fixed beamformers provide the signals for the loudspeakers in the target room, representing the synthesis of this auralization technique. Different methods of how such a beamformer can robustly be designed will be presented in this chapter.
