In this paper, an auditory virtual environment (AVE) is described that uses virtual microphone control (ViMiC) to address a 24-channel loudspeaker system based on ribbon speakers. In the newly designed environment, the microphones, with adjustable directivity patterns and axes of orientation, 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 AVE will be used with close-spot microphone techniques in two-way internet audio transmissions to avoid feedback loops and provide dynamic placement for a number of sources.
