i do talk about material sound. i do mixes and recordings in my younger years, and to my experience, in recording those two (freq and dynamics) must be treated or manipulated with different things. no matter how many points of surgical parametric eq we use, you can't manipupate dynamics. and some things in audio is like salt in soup. you can add, but you can never remove it. you can add water, but the whole taste is compromised. add a brick limiter, no way in earth you can add dynamics back to it.
