1. A wireless headset, comprising:

  • a first transceiver configured to receive a first audio input from a first source;

    a second transceiver configured to receive a second audio input from a second source;

    a memory configured to store a plurality of audio signal weighting coefficient sets, wherein each of the weighting coefficient sets corresponds to a predetermined mix of the first audio input and the second audio input, and each of the weighting coefficient sets includes a plurality of programmable digital weighting coefficient values;

    a controller configured to change the weighting coefficient values stored in the memory; and

    an audio mixer, coupled to the memory, configured to;

    select one of the weighting coefficient sets stored in the memory, the selected weighting coefficient set associated with a desired mix of the first audio input and the second audio input;

    weight the first audio input and the second audio input with the weighting coefficient values of the selected weighting coefficient set to produce a weighted first audio input and a weighted second audio input, wherein at least one of the weighting coefficient values weights the first audio input from the first source and at least one other of the weighting coefficient values weights the second audio input from the second source, andcombine the weighted first audio input and the weighted second audio input into output audio.
