1. In an audio system that controls an input audio signal to provide a controlled audio signal, a method for cancellation of lower sideband modulation distortion comprising:

  • generating a first signal which is a Hilbert transform of a signal associated with the control of the input audio signal;

    generating a second signal representative of a Hilbert transform of the input audio signal;

    multiplying the first signal and second signal to provide a third signal, and combining the third signal with the controlled audio signal.
