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 generate a plurality of windowed frames, wherein awindowed 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 provide an output frame comprising a number of output values, wherein anoutput frame is a spectral representation of a windowed frame.
