Tuning the Perceptual Noise Reduction Algorithm Using Rough Sets
暂无分享,去创建一个
As is shown by the results of some recently proposed methods, the perceptual coding of audio can be used for suppressing the noise affecting transmitted audio signals. The process of tuning the perceptual audio coding algorithm demands finding the relations between masking algorithm parameters and their influence on the subjective quality of processed audio. The rough set method was employed to discover ill-defined relations underlying the implemented perceptual model of hearing.
