Analysis Tool for Realtime Measurements using Perceptual Criteria"

Proc. of the 11th International AES Conference on Audio Test and Measurement, Portland 1992, pp.180-190

New evaluation techniques for quality assessment of audio channels have been developed using perceptual noise criteria. These techniques are not only useful for the analysis of perceptual coding schemes, but can also be applied to almost any audio signal processing. This paper describes a realtime measurement system based on the Noise-to-mask ratio (NMR) algorithm. Several analog and digital applications of the system are presented to demonstrate the performance.
