frequencies will not be contributing to the output. Since the frequency was unwanted
anyway, there seems little point in allowing it to trigger the limiter.
Sometimes a graphic equaliser may be placed in the side chain of a limiter/compressor
and tune it to limit certain frequencies. The graphic equaliser is particularly good at this,
since it can notch very accurately. This is the usual way to remove sibilance (known as
"de-essing") or annoying background noises such as air-conditioning units etc.
