<P>PROBLEM TO BE SOLVED: To provide a device capable of executing a one bit audio signal processing while simplifying the programming. <P>SOLUTION: An operation section 110 with a bit stream given performs an arithmetic operation by sequentially extracting real number data defining a fade curve from a smaller number between the minimum and the maximum value from a fade carve storage section 120. When the bit stream is a digital value 1, a code part A of a fade curve definition value extracted is replaced with 0 and an exponent part B and a mantissa part C are output just as they are. When the bit stream is the digital value 0, the code part A of the fade curve definition value extracted is replaced with 1 and the exponent part B and the mantissa part C are output just as they are, so that a fade processing can be achieved with a very simple configuration. <P>COPYRIGHT: (C)2012,JPO&INPIT |
