How does one go about gaining this experience?
Seriously, take and heed the advice of others who have replied with imaging advice.
It's very cutthroat with voice work and such in DFW. A few get the big piece of
the pie, while the overwhelming majority get the crumbs, or get to lick the pan.
Having access to equipment is good too. Working your way into a station,
and doing it on the side (using their studio - as long as it isn't on their dime),
can be very beneficial. Home studios can be as cheap or expensive as you're
willing to invest. The big boys and girls who have been doing this for years
have invested thousands in their equipment and home studios (a feat that
can be challenging and downright impossible for a person right out of college).
My advice?
If you love radio dearly (as I assume you do), go back and get some
undergraduate work/degree working in the medical or health management
field (I'm not kidding!).
This field always has job openings, and you'll have something to fall back
on if things go south with the radio career. NEVER get a journalism or
communications degree. Those are about as good as the toilet paper
you wipe yourself with.
