Claim 1:
2. An apparatus according to claim 1,
characterized in that the analysis filter bank is adapted to transform the analysis filter bank input signal being represented in the time-domain into a first time-frequency domain audio signal having a plurality of first subband signals, wherein the number of first subband signals is equal to the first number of analysis filter bank channels,
wherein the apparatus further comprises a signal adjuster being adapted to generate a second time-frequency domain audio signal having a plurality of second subband signals from the first time-frequency domain audio signal based on a configuration setting, such that the number of second subband signals of the second time-frequency domain audio signal is equal to the number of synthesis filter bank channels, and wherein the number of second subband signals of the second time-frequency domain audio signal is different from the number of subband signals of the first time-frequency domain audio signal, and
wherein the synthesis filter bank is adapted to transform the second time-frequency domain audio signal into a time domain audio signal as the audio signal output of the synthesis filter bank.
