Is this a common vocal technique?

[BLP]

I tend to Lower the DB's of the low range and raise the mid and high range DB of the vocal.

depending on recorded vocal is how much db i alter.

THEN I add compression (customised to each vocal)


Basically I find it easier to sit the vocal in the mix this way

High pass filter is pretty common as a first step in mixing a lot of tracks to eliminate muddiness. Bumping the mids and highs tends to add clarity and "sparkle" to a vocal track. It can also add sibilance too though, so don't bump the db's too high.

What it boils down to is your last sentence, whatever works for you and your mix is the right thing to do, who cares if plenty of people do it?

I find cutting the mids a bit sometimes helps my vocal tracks, but that might be a characteristic of my mic.

A common technique? Sure, adjustments to the lower half might be slightly the more common area of eq -due to the trimming partly, plus maybe it's a little harder area to nail at tracking?
But what if we did some mic selection, a bit of low filter at the pre, then we played with the mic distance soes' it sounded like our best guess for a fit'?
The odds go down.
