AB  - This paper examines the design of psycho-acoustically optimal noise shaping filters for requantization in non-oversampling digital audio applications. The object is the minimize the total perceived output noise power. For this purpose, a new perceptual frequency-weighting function is introduced which provides closer matching to the ear's measured sensitivity at high frequencies than do existing functions. Corresponding filter designs are investigated. In addition, the importance of DAC linearity is discussed with regard to realizing the potential audible benefits of noise shaping.
