1. A method for mixing an N-channel input audio signal to generate an M-channel output audio signal, where N and M are positive integers, the method comprising the steps of:

  • (a) generating a first loudness measure for the N-channel input audio signal;

    (b) mixing N input channel signals corresponding to the N-channel input audio signal to generate M mixed channel signals;

    (c) generating a second loudness measure for the M mixed channel signals; and

    (d) equalizing the M mixed channel signals based on the first and second loudness measures to generate the M-channel output audio signal.
