That is good info and worth noting, but it is not really frequency

Frequency range: The minimum to maximum frequencies present

that is diminished as much as dynamic range

Dynamic range: The ratio, in dB, between the largest and smallest signals simultaneously present

I would only use hard limiting with amplification on a recording that was difficult to listen to otherwise and most often I use just hard limiting without amplification to flatten out a crowd applause or other non music portion of a recording
