Abstract:
1. A decoder arrangement, comprising: a receiver input for parameters of frame-based coded signals; a decoder connected to said receiver input, arranged to provide frames of decoded audio signals based on said parameters; a postfilter connected to an output of said decoder and arranged to provide an output signal based on said frames of decoded audio signals; wherein at least one of said receiver input and said decoder is arranged to establish a time difference between the occasion when parameters of a first frame (x(n)) is available at said receiver input and the occasion when a decoded audio signal of said first frame (y(n)) is available at said output of said decoder, which time difference corresponds to at least one frame; the postfilter further arranged to receive said first frame of the decoded audio signals (y(n)) essentially simultaneously as the parameter of a respective subsequent frame (x(n+1)); wherein said postfilter is connected to said receiver input; and, wherein said postfilter is arranged to provide a filtering of said first frame of the decoded audio signals (y(n)) into an output signal (y
