1. A method of decoding a digital signal in media, the method comprising:

  • using a computer programmed as a decoder to perform the acts of;

    computing signal characteristics of a host signal in which a digital signal is encoded;

    analyzing the characteristics to determine an extent to which the signal characteristics correspond to characteristics of the digital signal; and

    adapting parameters of a predictive filter applied to the host signal based on the extent to which the signal characteristics correspond to the characteristics of the digital signal;

    wherein the parameters adapt the function of the predictive filter based on the signal characteristics.
