The stereophonic perception in a system with adjusted "sweet spot" was theoretically investigated on the basis of an analytical model and an advanced binaural model. Both approaches indicated that an adaptive adjustment of the signals relative to the center of the listener's head improves the localization over the whole listening area. Moreover, the best results in localization stability can be achieved for "intensity" stereo with combined time and level adjustment. However, adaptive signal adjustment in reference to the center of the listener's head still results in a small localization error, which could be estimated and compensated for using a binaural model.
