AB  - The modal analysis of a room response is considered, and a computational structure employing a modal decomposition is introduced for synthesizing artificial reverberation. The structure employs a collection of resonant filters, each driven by the source signal and their outputs summed. With filter resonance frequencies and dampings tuned to the modal frequencies and decay times of the space, and filter gains set according to the source and listener positions, any number of acoustic spaces and resonant objects may be simulated. Issues of sufficient modal density, computational efficiency and memory use are discussed. Finally, models of measured and analytically derived reverberant systems are presented, including a medium-sized acoustic room and an electro-mechanical spring reverberator.
