Abstract
A digital audio processor comprises at least one digital audio sample mapping module and produces a sequence of output digital audio sample values by applying a quasi time-invariant transfer function to each input digital audio sample value, the transfer function being arranged so that a ratio of root mean square signal level to peak signal magnitude is lower for the input digital audio signal than for a corresponding portion of the output digital audio signal.
