Abstract

A real-time system for immersive audio applications is presented. Sound sources are recorded using a microphone array whose beam is steered according to the output of an acoustic source localization and tracking system. The output of the beamformer (BF) along with the source position updates are continuously transmitted to a wave field synthesis (WFS) system. By using WFS, the sound sources in the recording room are rendered in the reproduction room with the correct spatial cues.
