1. A processor for processing a digital audio signal, comprising:

  • a Delta Sigma Modulator for processing said digital audio signal as a 1-bit signal at a first sampling rate S1 on the basis of a set of coefficients generated from a set of signal parameters;

    a plurality of manually adjustable controls for setting said set of signal parameters;

    reading means for reading the signal parameters set by said plurality of manually adjustable controls at a second sampling rate S2;

    wherein the first sampling rate S1 is at least n times the second sampling rate S2;

    coefficient generating means for generating, in n increments, coefficients corresponding to changes in the read signal parameters and supplying the incrementally generated coefficients to the Delta Sigma Modulator at the first sampling rate S1;

    whereby adjustments to the set of signal parameters are smoothly applied by the processor.
