We've all had sessions where we put up our go-to vocal mic, listen to the singer's first take, and realize "that's not the right mic for this song!"
The question is, what do you do next?
I see photos periodically where guys hang up six mics in a cluster. It makes a great photo op, but I'm not sure any of those 6-way mic tests fairly represent the mics in question. Some of those mics are (relatively speaking) a lot farther away from the singer than others.
Ronan Chris Murphy described his process at the Mountain Recording Retreat
recently. He puts up two mics, has the artist sing a verse and a chorus, then listens to the results. They pick the winning mic, and replace the losing mic with another choice. Rinse and repeat. 15 minutes later, they've heard a handful of mics, and whatever is left standing is apparently the best of the available mics for that particular track.
How do you manage vocal mic selection?
(Even if you don't have a bunch of classic LDCs to choose from, it's absolutely worth auditioning whatever you have. You never know what might win for any given song.)
