AB  - A synthesis technique incorporating a circular phased-array microphone is described where the horizontal polar response is matched to an arbitrary set of head-related transfer functions (HRTFs). The array can emulate the function of an artificial listener but without the need to embed physical anatomical features. Design techniques are described based upon polar response equalization computed over a discrete frequency space which together with dynamic coefficient processing enables spatial image manipulation and bespoke multi-listener environments with individual head tracking. A method of 2-D spatial filtering is described to scale the number of microphone signals. Applications include binaural recording optimally matched to an arbitrary number of listeners, distributed gaming, teleconferencing, multi-user interactive virtual reality and remote surveillance.
