Claim 11:
12. A method for processing an audio signal to acquire an audio output signal, comprising:
processing an audio signal to obtain a first processed audio signal, wherein a sampling rate of the first processed audio signal is controlled in accordance with a configuration setting received at run time,
controlling a first number of analysis filter bank channels of an analysis filter bank and a second number of synthesis filter bank channels of a synthesis filter bank, so that an audio signal output by the synthesis filter bank has the predetermined sampling rate or a sampling rate being different from the predetermined sampling rate and being closer to the predetermined sampling rate than the sampling rate of an input signal into the analysis filter bank to acquire the audio output signal, and
wherein the analysis filter bank transforms the input signal into the analysis filter bank from a time-domain to a time-frequency domain, and
wherein the synthesis filter bank conducts a transformation from the time-frequency domain to the time domain to acquire the audio output signal.
