	abstract = {An artificial reverberator having low memory requirements and small computational cost is presented. The reverberator consists of an equalized comb filter driving a convolution with a short noise sequence, which can consist of Gaussian or velvet noise. The reverberator\&nbsp;equalization and decay rate are controlled by low-order IIR filters, and the echo density is\&nbsp;that of the noise sequence. While this structure is efficient and readily generates high echo\&nbsp;densities, if a fixed noise sequence is used, the reverberator has an unwanted periodicity at the\&nbsp;comb filter delay length. To overcome this difficulty, the noise sequence is regularly updated\&nbsp;or \&ldquo;switched.\&rdquo; Several structures for updating the noise sequence, including a leaky integrator\&nbsp;sensitive to the signal crest factor, and a multiband architecture, are described.},
