Abstract
An acoustic image source model for early reflections in a room is generated by iteratively mirroring (305) rooms around boundaries (e.g. walls) of rooms of the previous iteration. The boundaries around which to mirror in each iteration is determined (303) by a specific selection criterion including requiring that mirror directions cannot be reversed, cannot be in an excluded direction and cannot be repeated unless in a continuous series of mirrorings.
