"WebThe term, “DC Offset,” is commonly used by audio engineers to describe this operation. From the days of analog circuits, there were two types of current: direct current (DC) and alternating current (AC). When direct current was applied to alternating current, the result was a signal shifted away from zero. " - Dc offset python
