Abstract

In this paper, the virtual implementation of classic microphone techniques is described. The system is presently being used to address an array of 24 ribbon loudspeakers. In the newly designed virtual 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 augmented ITU surround-sound loudspeaker placement and to create sound imagery similar to that associated with standard sound recording practice. The audio environment is used with spot-mic recordings in two-way Internet audio transmissions to avoid feedback loops and to provide dynamic placement for a number of sources
