The Switched Convolution Reverberator
High-quality artificial reverberators, which are well known, generally have large memory and computational costs. An alternative architecture attempts to manage quality separately for steady-state and transient signals. The proposed reverberator consists of an equalizing comb filter with an embedded convolution with a short noise sequence. To overcome the difficulty of unwanted periodicity with transients, the noise sequence is regularly updated. Several methods for updating the noise sequence, including a leaky integrator or a multiband structure are described. Informal listening tests are encouraging.
