Signal requantization to reduce the word-length of an audio stream introduces distortions. Noise shaping can be applied in combination with a psychoacoustic model in order to make requantization distortions minimally audible. The psychoacoustically optimal noise shaping curve depends on the time-varying characteristics of the input signal. Therefore, the noise shaping filter coefficients are to be computed and updated on a regular basis. In this paper, we present a new theory for optimal noise… Expand

Minimally Audible Noise Shaping
Normal quantization or requantization noise is white, but the ear's sensitivity to low-level broad-band noise is not uniform with frequency. By adopting a suitable weighting curve to representExpand
