Abstract: front page image
(EN)An encoder for encoding an audio signal comprising: a first coder-decoder configured to generate from a first audio signal a second audio signal; a signal comparator configured to determine at least one energy difference value between the first audio signal and the second audio signal; and a signal processor configured to calculate at least one signal shaping factor dependent on the at least one energy difference value.
