Gobo – Definition & Detailed Explanation – Recording Techniques Glossary

What is a gobo?

A gobo, short for “go between,” is a device used in recording studios to control the acoustics of a room. It is typically a movable panel or screen that is placed between a sound source and a microphone to alter the sound waves before they reach the microphone. Gobos are commonly used to reduce unwanted reflections, echoes, and background noise in a recording environment.

How are gobos used in recording?

Gobos are used in recording to create a more controlled and isolated sound environment. By strategically placing gobos around a microphone or sound source, engineers can manipulate the way sound waves travel and interact with the room. This can help to reduce unwanted reverberations, echoes, and background noise, resulting in a cleaner and more focused recording.

What materials are gobos typically made of?

Gobos can be made from a variety of materials, depending on their intended use and budget. Common materials used for gobos include foam, fiberglass, wood, metal, and fabric. Foam and fiberglass gobos are popular choices for their sound absorption properties, while wood and metal gobos are often used for their durability and ability to block sound.

How do gobos affect sound in a recording environment?

Gobos can have a significant impact on the sound quality of a recording environment. By absorbing or reflecting sound waves, gobos can help to control the acoustics of a room and reduce unwanted noise. Gobos can also be used to create a more intimate or spacious sound, depending on their placement and material.

What are the different types of gobos available?

There are several different types of gobos available for recording studios, each with its own unique properties and benefits. Some common types of gobos include:

– Absorption gobos: These gobos are designed to absorb sound waves and reduce reflections, echoes, and background noise.
– Diffusion gobos: These gobos are designed to scatter sound waves and create a more even distribution of sound in a room.
– Isolation gobos: These gobos are designed to block sound waves and create a more isolated sound environment.
– Portable gobos: These gobos are lightweight and easy to move, making them ideal for temporary or mobile recording setups.

How can gobos be DIY’d for home recording setups?

For those looking to create their own gobos for home recording setups, there are several DIY options available. One popular method is to use bookshelves, mattresses, or curtains as makeshift gobos to absorb or block sound waves. Another option is to build custom gobos using materials like plywood, foam, and fabric. By experimenting with different materials and placements, home recording enthusiasts can create their own customized gobos to improve the sound quality of their recordings.
