In a corner, the two walls will form half of your booth so all you need to add is a stand or frame to drape a blanket around. If you’re building an enclosed DIY recording booth, then you will need a structure. You don’t need to build a complete frame and your task is simple. If you are looking to build an open-plan acoustic corner, there isn’t much to do except hang some sound absorbing blankets or foam (see below). This is the frame or the outside of your booth and will be different depending on whether you’re building a DIY recording booth that is open-plan or not.
