1. A system comprising:
a microphone to convert an acoustic signal to an electrical signal; and
at least one processor circuit to:
estimate a distance between a source of the acoustic signal and the microphone;
compare the distance to a threshold;
select a first processing mode as a selected processing mode when the distance is less than the threshold;
select a second processing mode as the selected processing mode when the distance is greater than the threshold;
process the electrical signal in accordance with the selected processing mode,
wherein the first processing mode includes a first set of processing operations and the second processing mode includes a second set of processing operations, the first set including a fewer number of processing operations than the second set.
