VARIABLE ANR TRANSFORM COMPRESSION

摘要

Apparatus and method of reducing the provision of ANR at an one end of a range of frequencies at which the ANR is provided without reducing the provision of the ANR at the other end of the range of frequencies by repeatedly reconfiguring coefficients of one or more digital filters to reduce the provision of ANR at the one end in increments at a first recurring interval, and then later reversing the reduction in the provision of the ANR at the one end by repeatedly reconfiguring coefficients of the one or more digital filters in increments at a second recurring interval.
