Wave Field Synthesis is a well-established high-resolution spatial sound reproduction technique. Its physical basis allows to reproduce almost any desired wave field, even sound sources positioned in between the loudspeakers and the listener. Such sources are known as focused sources. Focused sources have a number of remarkable physical properties, especially in the context of spatial sampling. This paper presents a detailed analysis of the physical properties of focused sources as well as their perceptual impact. Additionally, results of a first informal listening experiment are discussed in order to gather knowledge on the perceptual relevance of the derived artifacts in practical implementations.
