Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a synthetic filter bank for a low delay digital audio system.

SOLUTION: A synthetic filter bank 200 includes a frequency/time converter 210 for outputting a plurality of output frames in which the respective output frames are time display of input frames. The synthetic filter bank includes a window processing part 220 and the window processing part is constituted so as to output a plurality of samples after window processing for processing by a duplicate system based on a sample preceding value. The synthetic filter bank includes an overlap/adder 230 for outputting frames after addition by overlapping the frames after the window processing to add the sample preceding value and at least three samples after the window processing from at least three frames after the window processing are aggregated for one sample after the addition of the frames after the addition. The sample preceding value is smaller than a number obtained by dividing the number of samples after the addition of the frames after the addition by 2.
