English term or phrase: bias
a biased distortion metric may be used, which is given as the biased energy difference between the original audio signal vector S and the composite reconstructed signal vector

βj may be a bias term which is used to supplement the decision of choosing the perceptually optimal gain error index j*.

For example, although the error weighting function W may be used to attempt to "whiten" the error spectrum to some degree, there may be certain advantages to placing more weight on the low frequencies, due to the perception of distortion by the human ear. As a result of increased error weighting in the low frequencies, the high frequency signals may be under-modeled by the enhancement layer. In these cases, there may be a direct benefit to biasing the distortion metric towards values of gj that do not at-tenuate the high frequency components of Sj, such that the under-modeling of high frequencies does not result in objectionable or unnatural sounding artifacts in the final reconstructed audio signal.

In another case, the bias factors βj may be based on other signal characteristics of the input audio and/or core layer output audio signals.
