VU-Meter / Bio-Feedback device to help reduce over-singing
I wonder if there is such a thing as a visual VU meter for singers?
It would have to have a tight super-cardiod pattern and possibly extend right out from the side of your mic?
Maybe the main read-out part could clip onto your mic stand that would let you know if you are exceeding your voice's safe volume levels?
That would in essence function as a sort of realtime bio-feedback device to ensure you are not over-singing despite the ever-changing stage setup.
Could be as important a tool as a guitarist's clip on tuner.
Has anyone ever heard of such a thing?
(... if not, maybe I need to create it)
