Abstract
In methods and apparatus for performing temporal noise shaping, an apparatus may have a temporal noise shaping, TNS, tool for performing linear prediction, LP, filtering on an information signal including a plurality of frames; and a controller configured to control the TNS tool so that the TNS tool performs LP filtering with: a first filter whose impulse response has a higher energy; and a second filter whose impulse response has a lower energy than the first filter, wherein the second filter is not an identity filter, wherein the controller is configured to choose between filtering with the first filter, and filtering with the second filter on the basis of a frame metrics.
