A decoder for decoding a plurality of spectral-domain audio samples is provided. The decoder comprises a first decoding module (110) for generating a first group and a second group of time-domain intermediate audio samples from the spectral-domain audio samples. Moreover, the decoder comprises an overlap-adder (130) for overlap-adding the first group of time-domain intermediate audio samples with an overlap of more than 5 % and at most 50 % with the second group of time-domain intermediate audio samples. Furthermore, the decoder comprises a second decoding module (120) for generating a third group and a fourth group of time-domain intermediate audio samples from the spectral-domain audio samples. Moreover, the decoder comprises an output interface (140). The overlap-adder (130) is configured to overlap-add at least the third group of time-domain intermediate audio samples with an overlap of more than 60 % and less than 100 % with the fourth group of time-domain intermediate audio samples. Moreover, the overlap-adder (130) is configured to overlap-add at least the second group and the third group of time-domain intermediate audio samples, or to overlap-add at least the fourth group and the first group of time-domain intermediate audio samples.
