Dynamic Range Enhancement Using Noise-Shaped Dither Applied to Signals with and without Pre-emphasis
This paper presents new noise-shaped dithers designed to give increased subjective dynamic range when applied to signals with and without pre-emphasis. The advances in the auditory model which have led to improved spectral-density specification and assessment of performance are described. The techniques for designing, implementing and measuring noise-shapers with and without pre-emphasis are discussed.
