1. An apparatus for processing an audio signal, comprising:
a configurable audio signal processor for processing the audio signal in accordance with different configuration settings to obtain a processed audio signal, wherein the apparatus is adapted so that different configuration settings result in different sampling rates of the processed audio signal,
an analysis filter bank having a first number of analysis filter bank channels, wherein the analysis filter bank is adapted to transform an analysis filter bank input signal from a time-domain to a time-frequency domain,
a synthesis filter bank having a second number of synthesis filter bank channels, wherein the synthesis filter bank is adapted to transform an output of the analysis filter bank from the time-frequency domain to the time domain to produce an audio signal output of the synthesis filter bank,
a controller for controlling the first number of analysis filter bank channels or the second number of synthesis filter bank channels in accordance with a configuration setting provided to the configurable audio signal processor, so that the audio signal output of the synthesis filter bank has a predetermined sampling rate or a sampling rate being different from the predetermined sampling rate and being closer to the predetermined sampling rate than a sampling rate of the analysis filter bank input signal
wherein the apparatus is adapted to receive the configuration setting at run time.
