Boundary mics are a great solution for difficult sound pickup challenges. They are particularly useful when deployed on conference tables and podiums, thanks to the mic's dependence on proximity to an adjacent surface, or boundary. A boundary mic's small size and low profile are also advantageous visually when hardware clutter must be kept to a minimum.
The sonic character of boundary microphones tends to be extremely natural and uncolored, with a noticeable absence of room reflections or reverberation. This behavior makes surface mics a popular choice for recording live audio, as well as when used in general sound reinforcement applications.
