Objective Perceptual Analysis: Comparing the Audible Performance of Data Reduction Schemes

Document Thumbnail

Data reduction schemes, such as DCC and MiniDisc in domestic high-fidelity, DAB in broadcasting, and GSM and DCMEs in telecommunications, are not adequately characterized by simple engineering performance metrics. The paper introduces the emerging field of perceptual analysis for predicting subjective opinion. A practical perceptual analysis is used to analyse and compare example data reduction schemes and its usefulness is discussed.
