Abstract

End-to-end audio quality measurement of non-linear communication networks requires existing codec assessment models to be extended. Variable delay in voice over IP systems and linear filtering in analogue interfaces are shown to cause problems. Results suggest that a perceptual analysis/measurement system (PAMS) can take account of these effects and is robust for end-to-end assessment.
