Hi,
The CNF should be able to remove low frequency noise. Two things are critical to know about it, however.
You need to use a large fft size (16,384) to improve its effectiveness on the bottom end of the spectrum. Also, you may have to "tweek" the blue graphical inflection points (sometime called "touch points") for optimal results at the bottom end. Give that a try.
