Boundary microphones (discussed in Chapter 7) can make excellent stereo recordings. This Appendix explains the characteristics of several boundary-mic arrays.
First, here are some ways to create basic stereo arrays using boundary microphones (Bartlett, 1987):
- To make a spaced-pair boundary array, space two boundary microphones a few feet apart. They can be omni or unidirectional. Place them on the floor, on a wall, or on stand-mounted panels.
- To make a coincident array, mount two omni boundary mics back-to-back on a 2-foot × 2-foot clear plastic panel, with the edge of the panel aiming at the sound source.
- To make a near-coincident array, mount each omni boundary microphone on a separate panel, and angle the ...
