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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Active phantom-powered ribbon microphone with switchable proximity effect response filtering for voice and music applications","description":"Novel active phantom-powered ribbon microphones that provide switchable proximity effect response filtering for voice and music applications are disclosed with unique adjustable interfaces.
