Abstract
The audio circuit has a volume circuit structured to process a DSD signal that contains DSD data and a DSD clock. The volume circuit has a first shift register and a replacement circuit. The first shift register holds N bits of the DSD data. The replacement circuit replaces (N−M) bits (0≤M≤N) corresponding to a gain set value, out of N bits stored in the first shift register, with a mute bit string having a mark rate of substantially 50%.
