Abstract
Embodiments of noise reduction systems and methods are disclosed. One method embodiment, among others, comprises transforming a residual signal to produce transform coefficients, and applying the transform coefficients to a quantization matrix and a configurable gain matrix to provide a frequency-selective weighting of the transform coefficients having a gain that is sensitive to noise levels.
