Original Abstract Submitted

an acoustic image source model for early reflections in a room is generated by iteratively mirroring () rooms around boundaries (e.g. walls) of rooms of the previous iteration. determination of mirror positions in the image rooms for an audio source in the original room is performed by determining () matching reference positions in the two rooms and a relative mapping of directions between the two rooms (). a mirror position in the mirror room from an audio source in the original room is determined () by mapping relative offsets between the positions of the audio source and the reference positions. the approach may provide a computationally very efficient approach.
