1. Apparatus for generating a delayed output digital audio signal from an input digital audio signal, the apparatus comprising:

  • a first delay module adapted to apply a first amount of delay to the input digital audio signal to generate a partially delayed digital audio signal, wherein the first delay module is adapted to select the first amount of delay from a plurality of available first delay values separated from one another by increments at a first resolution level; and

    a second delay module adapted to apply a second amount of delay to the partially delayed digital audio signal to generate the delayed output digital audio signal, wherein the second delay module is adapted to select the second amount of delay from a plurality of available second delay values separated from one another by increments at a second resolution level different from the first resolution level.
