Abstract: Problem to be Solved To effectively operate a microphone array provided with a sound source position estimating function. Solution A microphone control system of the present invention is realized by the use of a tablet-type computer, for example. On the display of the control system, a two-dimensional simulation diagram 302, for example, simulating the space in which the microphone array is disposed. An array mark 304 simulating the exterior shape of the microphone array is displayed on the simulation diagram 302. Further, a sound source mark 316 indicating the position of the sound source estimated by the microphone array is displayed on the simulation diagram 302. Thus, an operator can intuitively find the position of the sound source in the space in which the microphone array is disposed, by referring to the simulation diagram 302, the array mark 304 and the sound source mark 316 displayed on the simulation diagram. Thus, the usage of the microphone array is improved.

Abstract: Novel active phantom-powered ribbon microphones that provide switchable proximity effect response filtering for voice and music applications are disclosed with unique adjustable interfaces. In one embodiment of the invention, a slider-based full frequency response vs. low frequency response and high pass filtering adjustment interface on a surface of a microphone casing provides a convenient switching between a “Music” mode and a “Voice” mode, wherein the “Voice” mode reduces the undesirable proximity effect in an active phantom-powered ribbon microphone, when a sound source is situated overly close to the active phantom-powered ribbon microphone. Furthermore, in one embodiment of the invention, a slider-based or a knob-based variable voice mode adjustment interface can also be integrated on a surface of a microphone casing to provide various preset levels of low frequency reduction and/or proximity effect response filtering when the “Voice” mode is enabled.
