Gobo is a slang term used by sound recording engineers to refer to a movable acoustic isolation panel.

GoBo - A freestanding device used to inhibit the propagation of sound waves. Gobos are usually employed to prevent microphone leakage between two instruments being recorded simultaneously. Typically a set of portable dividers covered with acoustical treatments.

I'm designing some gobo panels, each about 3' x 7', containing 3" of Roxul Safe-n-Sound. I will join them in pairs with hinges.

I'm wondering if I should fabric both sides, or put a hardboard backer on the back?

This is the drums/bass of the new piece ... nevermind the timing errors. I'll fix those ... but did the drums lose the room sound better?

We employed close gobos and blankets.

Thanks for the ears!

I built myself three 4 ft x 6 ft gobos, each made from a framed piece of ¾ inch plywood, a layer of 1/8 inch high-mass vinyl, and three 2x4 batts of acoustical/fire rockwool. Each batt is wrapped first in light tracing paper to keep fibers in, then all the batts are wrapped in theatrical polyester muslin fabric, which is durable and fire-resistant, if not entirely acoustically transparent.

I have this problem almost licked, except for one "fly in the ointment". I have succeeded in having the ablilty to record a vocal track into my DAW via a LD condenser and a Joemeek VC3Q, and simultaneously record direct to DAW with my Kurzweil synth/workstation.

Just wondering if there's a commercially built (good quality) gobo out there that I can buy. I don't have any tools but have access to some, plus there's a home depot down the street.
