Objective spatial audio quality measurement systems attempt to predict the perceived quality degradation reported in subjective tests by comparing an original reference and a processed version of the same signal. In this context, binaural processing can be used in conjunction with a perceptual model for improved prediction performance. This paper investigates how variations in the binaural processor namely head rotations, added reverberation, and simulated room properties impact the prediction performance of a standardized objective audio (Perceptual Evaluation of Audio Quality PEAQ) quality measurement scheme that has been extended to include spatial aspects.
