Abstract  Abstract

PROBLEM TO BE SOLVED: To provide low codec delay which is indispensable in many fields of application such as telecommunication.

SOLUTION: A synthetic filter bank 100 for filtering a plurality of time domain input frames comprises a window processing section 110 in which the respective input frames include a plurality of input values 110i aligned in good order and for generating a plurality of frames after window processing in which the respective frames after window processing include a plurality of samples after window processing the window processing section processes the plurality of input frames in a duplication system by using a sample preceding value and the sample preceding value is smaller than a number obtained by dividing the number of aligned input samples in one input frame by 2. In addition the synthetic filter bank 100 comprises a time/frequency converter 120 for outputting output frames of a plurality of output values 110o and the output frames are time display of the input frames.
