Abstract  Abstract

Abstract: There is disclosed a synthesis filterbank for filtering a plurality of input frames each input frame comprising M ordered input values Yk(O)...yk(M-l) wherein M is a 5 positive integer and wherein k is an integer indicating a frame index comprising: an inverse type-IV discrete cosine transform frequency/time converter configured to providing a plurality of output frames an output frame comprising 2M ordered output samples xk(O)...Xk(2M-l) based 10 on the input values yk(O)...yk(M-1); a windower configured to generating a plurality of windowed frames a windowed frame comprising a plurality of windowed samples Zk(O) . zk(2M-1) based on the equation zk(n) = w(n) - xk(n) for n = 0... 2M-1 wherein n is an integer indicating a 15 sample index and wherein w(n) is a real-valued window function coefficient corresponding to the sample index n; an overlap/adder configured to providing an intermediate frame comprising a plurality of intermediate samples mk(O) ...mk(M-1) based on the equation mk(n) = zk(n) + Zk. 20 1 (n+M) for n = 0...M-1 ; and a lifter configured to providing an added frame comprising a plurality of added samples outk(O)...outk(M-1) based on the equation outk(n) = mk(n) + l(n-M/2) - mk.l(M-1-n) for n = M/2...M-1 ; and outk(n) = mk(n) + l(M-1-n) outk.l(M-1-n) for 25 n=O...M/2-l wherein l(O)...l(M-l) are real-valued lifting coefficients. 2609100.1 (GHMatters) P80447.AU.1 FIG 1 SUBSTITUTE SHEET (RULE 26)
