An extension of the PEAQ measure by a binaural hearing model

Instrumental evaluation of the perceived audio signal quality is an important tool for the development of audio signal enhancement and transmission systems. There are various single channel measures which can be used for different application scenarios. Binaural signals have not received much focus so far and no sophisticated model of spatial perception is utilized in the available measures. In this contribution, an extension to Perceptual Evaluation of Audio Quality (PEAQ) is presented which makes use of a recently proposed binaural hearing model. It is shown that the inclusion of spatial information into the instrumental quality measurement leads to a strongly increased correlation between the instrumental measure and a listening test.
