Basically a multi-channel equalizer and limiter, though no noise filtering is noted.
BHI does have a parametric equalizer, but otherwise most of its product line is known for the company's digital noise filtering routine(s).
I have not used BHI noise filtering, but I do have a couple of now ancient Timewave DSP-9 noise filters. They are decent for narrow CW filtering and filtering, plus cleaning up some of the background noise in casual SSB voice listening.
With SDRs these days I like SDRSharp for its integrated IF, audio, etc. digital noise filters. Otherwise I sometimes pipe audio through EasyEffects to use RNNoise and/or DeepFilterNet algorithms. StereoTool's dehummer and noise gate filters can also help cleanup background band noise.
