Abstract (en)

A signal is divided into frequency ranges which are transformed for spectral distribution into at least one coefficient file. Harmonic decomposition of the coefficient file is then performed followed by sample allocation. When transforming each of the frequency ranges, first transformation is performed based on frequency division and second transformation is performed based on time division. Independent claims are also included for the following: (1) a computer program product; (2) a pattern recognition device; and (3) the coefficient data.
