The 'SoundField by RØDE' NT-SF1 is a peerless ambisonic microphone that captures broadcast-quality 360° surround sound, offering unprecedented sonic possibilities for use in VR, sound design, immersive audio, and experimental recording applications. The NT-SF1 is the first collaboration between ambisonic pioneers SoundField (who invented the first commercial ambisonic microphone) and RØDE. Røde NT-SF1 Key Features Captures broadcast-quality 360° surround sound (with height) in A-Format™ on four separate tracks Four RØDE TF-45C ½-inch true-condenser cardioid microphone capsules arranged in a tetrahedral array Endless processing possibilities via the free 'SoundField by RØDE' plug-in Output to all formats, from stereo to 7.1.4 surround sound Comes in a complete recording kit, including a custom suspension shockmount, Blimp-style windshield and furry wind cover Record Everything The NT-SF1 records the entire spherical sound field – every sound from every direction – in perfect A-Format™ audio, which can be converted to B-Format™ audio and then manipulated infinitely using the 'Soundfield by RØDE' plug-in. Alter the mic directivity, position, and rotation after recording; create a full 7.1.4 surround mix; create a fully head-tracked 360° soundscape for immersive video. The possibilities are, quite literally, only limited by your imagination.
