Resampling output signals of qmf based audio codec

A method for processing an audio signal, comprising:

• transforming the audio signal from a time domain to another domain using an analysis filter bank comprising a first number of analysis filter bank channels,
• transforming the audio signal from the other domain to the time domain using a synthesis filter bank comprising a second number of synthesis filter bank channels, and
• controlling the first number of analysis filter bank channels or the second number of synthesis filter bank channels, so that an audio signal output of the synthesis filter bank comprises the 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 an analysis filter bank input signal.

A non-transitory computer-readable medium comprising a computer program for performing the method for processing an audio signal, said method comprising:

• transforming the audio signal from a time domain to another domain using an analysis filter bank comprising a first number of analysis filter bank channels,
• transforming the audio signal from the other domain to the time domain using a synthesis filter bank comprising a second number of synthesis filter bank channels, and
• controlling the first number of analysis filter bank channels or the second number of synthesis filter bank channels, so that an audio signal output of the synthesis filter bank comprises the 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 an analysis filter bank input signal.
