The binaural room scanning (BRS) auralization system relies on real-measured binaural room responses. The main applications is virtual representation of multichannel control rooms to realise optimum listening conditions in inadequate real conditions. In the developmental phase, artefacts due to necessary system simplifications can be eliminated. Thus the quality of the system primarily depends on human cues. An optimization of the BRS system with respect to the interindividual HRTF differences is reported.
