    • It is shown a decoder 110" for decoding an audio signal 32. The decoder 110" comprises a first target spectrum generator 65a for generating a target spectrum 85a" for a first time frame of a subband signal of the audio signal 32 using first correction data 295a. A first phase corrector 70a for corrects a phase 45 of the subband signal in the first time frame of the audio signal 32 determined with a phase correction algorithm, wherein the correction is performed by reducing a difference between a measure of the subband signal in the first time frame of the audio signal 32 and the target spectrum 85a". An audio subband signal calculator 350 calculates the audio subband signal 355 for the first time frame using a corrected phase 91 a for the time frame and for calculating audio subband signals 355 for a second time frame different from the first time frame using the measure of the subband signal 85a" in the second time frame or using a corrected phase calculation in accordance with a further phase correction algorithm different from the phase correction algorithm.
