A binaural model was used to investigate different microphone techniques (Blumlein, ORTF, MS, spaced omni). In contrast to previous attempts, the model algorithm was not only designed to predict the position, but also the spatial extent of a reproduced spatial image. The architecture of the model was designed to optimally process binaural cue distributions with multiple peaks as often found in psychoacoustical data. The model also contains elements to simulate the precedence effect, which is required for analyzing spacedmicrophone techniques, and is also useful when measuring the influence of the concert space on the recording.
