Abstract: PROBLEM TO BE SOLVED: To simplify an algorithm with a simple constitution by converging spectrum data transmittable in each processing width to an optimum transmission quantity with a dichotomy so as to control to obtain an optimum transmission quantity or less even of the number of converging times exceeds a certain number. SOLUTION: In an audio psychological analyzing circuit 91 for executing an audio psychological analysis, a masking effect to generate a non-recognizable area wherein a spectrum around the spectrum of some large sound is masked by the large sound, and minimum audible characteristics are considered. In order to normalize the ratio SMR of a signal level and a level to be masked, the circuit 91 gives a scale factor for normalization and the word length of the number of quantization bits to a multiplex circuit 92. As a transmission quantity required for the information transmission of a ratio SMR is too large to store in a transmission limit, an adjustment for storing within the limit is required.  Then, when it is known that there is one root in a set section, simple repeating of the arithmetic processing is executed with a dichotomy for obtaining an approximate value to simplify a circuit.
