An apparatus for providing ANR, comprising: a first ADC, a second ADC, a DAC； and a dynamically configurable digital signal processor (DSP) configured to: incorporate the first ADC, a first plurality of digital filters of a quantity and type specified by a first set of ANR settings, and the DAC into a first pathway； incorporate the second ADC, a second plurality of digital filters of a quantity and type specified by the first set of ANR settings, and the DAC into a second pathway； configure interconnections among the elements of the first and second pathways so that digital data from the first and second pathways are combined before flowing to the DAC； operate each of the digital filters using filter coefficients specified by the first set of ANR settings； transfer digital data through at least a portion of at least one of the first and second pathways at a data transfer rate specified by the first ANR settings； operate the first and second pathways to provide ANR； and change a parameter specified by the first set of ANR settings to a parameter specified by a second set of ANR settings in synchronization with a transfer of digital data along at least a portion of at least one of the first and second pathways.
