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 …

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.

abstract={considering high-resolution, multi-channel audio, it is worth re-examining the concept of psychoacoustically optimized noise shaping to ensure that signal quality is preserved when word-lengths are reduced. in this paper, approaches in static (time-invariant) and signal-adaptive (time-variant) noise shaping are discussed. we identify problems occurring …
