A Binaural Auditory Model for the Evaluation of Reproduced Stereophonic Sound
The use of computational operations instead of listening tests is common practice in monaural audio evaluation. However, the use of advanced binaural auditory models for the spatial sound evaluation remains a challenge. This article presents an interaural cross-correlation-based binaural auditory model that estimates both the direction(s) of the sound event(s) and the specific loudness spectra from a binaural recording. An experimental verification is used to evaluate the performance of the model in anechoic conditions and the model is applied in an analysis of the stereo-image width from binaural recordings made in non-anechoic conditions.
