Convention Paper

Measuring the Coding Margin of Perceptual Codecs with the Difference Signal

Authors: Feiten, Bernhard

AES Convention 102 · Paper 4417 · March 1997

Abstract

Inaudible impairments of impairments near the threshold of audibility require a new method to assess the quality. A variable amplification of the impairments to provide the detection can be realized with the help of the difference signal. In a large listening test, the coding margin for 14 test items was measured. A time varying filter bank to modify the difference signal and to enhance the listening conditions is described.
