The RØDE SoundField NT-SF1 is an unrivaled ambisonic microphone, capturing broadcast-quality 360° surround sound (including height) in A-Format™ across four separate tracks. This is the first collaboration between pioneering ambisonic microphone brand SoundField (who invented the first commercial ambisonic microphone) and RØDE Microphones. Precision crafted from solid brass, the NT-SF1 uses four RØDE TF-45C ½" cardioid true condenser microphone capsules arranged in a tetrahedral array to record the entire spherical sound field. Every sound, every direction, perfectly. Created in-house at RØDE's Sydney headquarters, the TF-45C is machined to tolerances of less than 1 micron in our manufacturing facilities. The result is a capsule of breathtaking clarity, sonic purity, and exceptionally low noise. Whether creating surround sound for video games, sports broadcasts, feature films, or virtual reality (VR) content, the NT-SF1 is perfect for all surround sound recordings and, because it is recorded in A-Format™ and easily converted to B-Format™, it can be manipulated in any direction in post-production. Using RØDE's free SoundField plugin, you are the architect of the soundscape and can change the directionality, position, and rotation of the mic. Create a full 7.1.4 surround mix. Create a 360-degree soundscape with head tracking for immersive video. Whether you're recording an opera, a swamp, or a feature film, the NT-SF1 offers unmatched quality and flexibility. The SBR plugin has all the standard surround sound configurations, including Dolby Atmos up to 7.1.4, and is supported by Protools, Q-base, Nuendo, Reaper, and Logic in VST, AU, or AAX formats, all with legendary RØDE ease of use. The NT-SF1 comes in a complete kit, including a custom-made suspension damper, a ball-shaped windshield, and a DeadCat windscreen. All delivered in a stunning presentation box.
