摘要：An embodiment of an analysis filterbank for filtering a plurality of time domain
input frames, wherein an input frame comprises a number of ordered input samples,comprises a windower configured to generating a plurality of windowed frames, whereina windowed frame comprises a plurality of windowed samples, wherein the windower isconfigured to process the plurality of input frames in an overlapping manner using asample advance value, wherein the sample advance value is less than the number ofordered input samples of an input frame divided by two, and a time/frequency converterconfigured to providing an output frame comprising a number of output values, whereinan output frame is a spectral representation of a windowed frame.
