✦ Synopsis

The theory in reference [1], for a source in rectilinear motion, using time variant analysis and an invariant surface flux source description, is extended here to include arbitrary source motion. The special case of a small rigid object is considered, with motion in a circle used as a simple example. The effect of convective motion is expressed entirely through changing amplitude and time scales, both of which are given in terms of a single time varying factor.
