@conference {3233, title = {A Reverberator with Two-Stage Decay and Onset Time Controls}, booktitle = {129th Audio Engineering Society Convention}, year = {2010}, note = {\ }, month = {11/2010}, address = {San Francisco, CA, USA}, abstract = {\ An efficient artificial reverberator having two-stage decay and onset time controls is presented. A second-order comb filter controlling the reverberator frequency-dependent decay rates and onset times drives a switched convolution with short noise sequences. In this way, a non-exponential reverberation envelope is produced by the comb filter, while the switched convolution structure produces a high echo density. Several schemes for generating two-stage decays and onset time controls with different onset characteristics in different frequency bands are described.}, keywords = {artificial reverberator}, author = {Lee, Keun Sup and Jonathan Abel} }
