A novel approach is proposed for maps illustrating the accuracy of image source position reproduced by stereo systems in various scenarios of listening rooms / loudspeakers. Based on previous work by the authors, the maps unify results derived from an image localization classifier and the sweet spot area metric estimating the direction of arrival angles (DOA) of all potential image source positions reproduced by the system via a perceptual model. The statistical analysis of these maps indicates the skewness and kurtosis of the DOA classification error and hence the consistency and robustness of the image definition along the plane of listener positions. Results utilize such parameter mappings to objectively illustrate the robustness of this qualitative aspect of audio reproduction in rooms.
