The "swish" energy is possibly full of highs and the loudest thing in the
recording, which is why a standard denoiser wont touch it. It's looking to
reduce low level sounds.

The swish will also probably contain frequencies way above that of the
wanted program, as well as above human audibility.
For access, I'd declick and then probably subjectively filter out a lot of
those highs, and even lows, but without an audio sample hard to be sure.
