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