Beschreibung
Zusammenfassung:	An apparatus for generating time-domain audio samples or synthesis filterbank (300) comprises a calculator (310) for calculating a frame (330) comprising a sequence of intermediate time-domain samples from audio subband values of block (320). The calculator (310) is coupled to a synthesis windower (360) to which the frame (330) of intermediate time-domain samples is provided. The synthesis windower (360) is adapted to windowing the sequence of intermediate time-domain samples using a synthesis window function (370) and provides a frame (380) of windowed intermediate time-domain samples. The synthesis windower (360) is coupled to an overlap-adder output stage (400) that obtains a block (410) of time-domain samples. The block (410) of the time-domain (output) samples can then for instance be provided to further components for further processing, storing or transforming into audible audio signals.
