GoBo

Short for “Go-Between.” A gobo basically forms a type of barrier: sometimes this can be between a light source and an area to be lighted where you want to keep the light off of part of it, or it can be to form a barrier for sound such that a particular sound source is shielded from a microphone during recording. Gobos are often used in recording studios for just this purpose. Say you have an acoustic guitar and a drum set in the same room. In order to help reduce the amount of drums bleeding into the acoustic guitar mic sound, absorbent panels, or gobos, are place between the drums and the guitar mic.
