摘要

Given the inherent restrictions on microphone placement when producing stereophonic recordings and/or sound reinforcement of live staged performances, it often is difficult to achieve an accurate aural image and sense of movement across the stage. For many years, the use of spaced floor-mounted microphones has been the norm for these performances, resulting however in acoustic interference anomalies that compromise the quality of these pickups. This presentation will demonstrate that by employing conventional coincident microphone techniques but mounted directly on the stage floor and in particular a central Mid/Side microphone pair configured as a boundary array an accurate and articulate stage image can be achieved without any of the comb-filtering or other phasing problems inherent to spaced microphones.
