Apparatus and method for generating audio subband values and apparatus and method for generating time-domain audio samples

An embodiment of an apparatus (100) for generating audio subband values ​​in audio subband channels comprises an analysis window generator (110) for windowing a frame (120) of input domain audio samples. times that are 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 window displays. The analysis window function (190) comprises a first set (200) of window coefficients and a second set (210) of window coefficients. The first set (200) of window coefficients is used to window subsequent time domain samples and the second set (210) of window coefficients is used to window earlier time domain samples. The apparatus (100) further comprises a calculator (170) to calculate the audio subband values ​​using the windowed samples.</p> <p>(Automatic translation with Google Translate, without legal value)
