So I've seen mentioned several times that one should only cut frequencies in EQ, and not boost. Could someone expand on why that's so? I've been curious about this lately, and don't recall ever seeing an explanation.
If I've come up with an EQ curve for a recording that sounds good to the ear, but boosts some frequencies, should I then reduce everything in the curve by an equal amount? I.E. so that the shape of the curve is retained, but everything is subtractive rather than additive?
