Title:

AUDIO CIRCUIT AND METHOD FOR REPRODUCING DSD SIGNAL

Document Type and Number:

WIPO Patent Application WO/2021/131908

Kind Code:

A1

Abstract:

An audio circuit 100 is provided with a volume circuit 110 that processes a DSD signal including DSD data and a DSD clock. The volume circuit 110 is provided with a first shift register 112 and a replacement circuit 114. The first shift register 112 holds N bits of the DSD data. The replacement circuit 114 replaces (N - M) bits (0 ≤ M ≤ N) corresponding to a gain set value among the N bits stored in the first shift register 112, with a bit string for muting having a mark rate of substantially 50%.
