Stereo Boundary-Microphone Arrays
Boundary microphones (discussed in Chapter 7) can make excellent stereo recordings. This chapter explains the characteristics of several boundary-mic arrays.
First, we look at ways to create basic stereo arrays using boundary microphones.
To make a spaced-pair boundary array, space two boundary microphones a few feet apart. Place them on the floor, a wall, or stand-mounted panels.
To make a coincident array, mount two boundary mics back to back on a large panel, with the edge of the panel aiming at the sound source.
To make a near-coincident array, mount each boundary microphone on a separate panel, and angle the panels apart. Or use two directional boundary mics on the floor, angled and spaced.
