METHOD AND APPARATUS FOR PERCEPTUAL EVALUATION OF AUDIO PRODUCTS

摘要

An improved method and apparatus employs psychoacoustic modeling to evaluate the distortions for audio products, such as multimedia sound cards, CD players, power amplifiers, loudspeakers, etc. The characteristic of this method and apparatus is to use psychoacoustic modeling to conform the measurements of distortion to human auditory perception. The proposed method and apparatus is to measure audio distortion for the audio products, not only for audio CODEC systems.
