Abstract
An embodiment of an apparatus (100) for generating audio subband values in audio subband channels comprises an analysis windower (110) for windowing a frame (120) of time-domain audio input samples being in a time sequence extending from an early sample to a later sample using an analysis window function (190) comprising a sequence of window coefficients to obtain windowed samples. The analysis window function (190) comprises a first group (200) of window coefficients and a second group (210) of window coefficients. The first group (200) of window coefficients is used for windowing later time-domain samples and the second group (210) of window coefficients is used for windowing an earlier time-domain samples. The apparatus (100) further comprises a calculator (170) for calculating the audio subband values using the windowed samples.
