Distortion device

Abstract

The invention provides a distortion device that allows obtaining a comfortable distortion sound across a wide input level range with a simple construction. An output with a distortion, Y=AX+BSX2 (here, A and B are constants, S is a value that becomes +1 or −1 according to a sign of the input X), is outputted from an input X. This calculating can be realized by an absolute value calculator (30) for calculating an absolute value of the input X, a multiplier (26) for multiplying the input X and an output from the absolute value calculator (30), a multiplier (27) for multiplying the input X by the constant A, a multiplier (28) for multiplying an output from the multiplier (26) by the constant B, and an adder (31) for adding an output from the multiplier (27) and an output from the multiplier (28)
