In auditory virtual environments it is often required to position an anechoic point source in three-dimensional space. When sources in such applications are to be displayed using multichannel loudspeaker reproduction systems, the processing is typically based upon simple amplitude-panning laws. This paper describes an alternative approach based on an array of virtual microphones. In the newly designed environment, the microphones, with adjustable directivity patterns and axis orientations, can be spatially placed as desired. The system architecture was designed to comply with the expectations of audio engineers and to create sound imagery similar to that associated with standard sound recording practice.
