Advancing Ambisonic recording

The Rode NT-SF1 is a compact, high-precision condenser microphone designed for 360° audio capture in Ambisonics A format. Its four-channel design captures a full-sphere sound image, making it ideal for immersive applications ranging from VR productions to spatial audio experiments. The "SF" designation honours SoundField, the company behind the first commercial Ambisonic microphone (1978). Now part of Rode's parent company (the Freedman Group, since 2016), the NT-SF1 makes professional Ambisonics accessible, merging SoundField's legacy with Rode's practical engineering. Combining decades of acoustic innovation with modern cost-efficient design, it delivers broadcast-ready 3D audio capture - equally suited to studio and field recording workflows.

Precision tetrahedral array

the Rode NT-SF1 features four phase-matched 0.5" TF-45C cardioid capsules are arranged in an optimised tetrahedral configuration, delivering exceptional spatial accuracy across a 20Hz-20kHz frequency range. With a robust maximum SPL handling of 129dB and low self-noise (15dBA per capsule), the NT-SF1 maintains clarity even in demanding recording environments. The proprietary JFET impedance converter and bipolar output buffer ensure signal integrity with a consistent 63-ohm output for stable long-cable runs. Complete with a custom 3m breakout cable, threaded stand adapter, and both foam and faux-fur windshields, it is field-ready for any scenario.

The immersive creator's toolkit

Engineered for VR sound designers, film audio professionals, and spatial audio pioneers, the NT-SF1 combines practical durability with technical sophistication. The solid brass body features a scratch-resistant ceramic coating, while its compact 286g form factor enables flexible placement. Rode's free SoundField plugin (VST/AAX/AU) transforms the four-channel capture into versatile formats - from binaural to 7.1.4 surround. Real-time spatial processing allows for intuitive soundfield orientation adjustments, while advanced decoding preserves phase coherence for critical applications. Whether capturing environmental ambisonics or creating interactive VR audio landscapes, the NT-SF1 delivers professional results with high workflow efficiency.

About Rode

Founded in Sydney, Australia in 1990, Rode is a specialist in high-quality studio microphones. With its very first in-house, completely Australian-built model, the NT2 large-diaphragm microphone, the company created a classic which is still produced in its current and enhanced version, the NT2-A. An extensive range of studio and live microphones has also been added, regularly updated, and expanded over the years. These new additions include a variety of professional microphones which are designed for video and mobile applications and can be connected directly to SLR cameras or smartphones.

Streamlined spatial workflow

The NT-SF1 combines simple setup with advanced capabilities. The included accessories support everything from studio mounting to handheld field recording, while the colour-coded XLR outputs simplify multi-channel routing. For optimum results, equal gain across all four channels must be maintained when recording. The SoundField plugin then provides comprehensive post-production control, including dynamic soundfield rotation, real-time format conversion from stereo to 7.1.4 surround, head-tracking integration for VR workflows, and beamforming for focused spatial capture. With a plugin latency of 882 samples, the NT-SF1 brings broadcast-ready Ambisonic capture within reach of content creators at all levels.

For Anyone Interested in Recording 360º (2π) Sound
IMAGE St Clair 26.10.2022
This Soundfield ambisonic microphone from Røde is a lovely thing, beautifully engineered and aesthetically pleasing. Of course, this concept of 360º reality sound is misleading as it uses a 2-dimensional measure in a 3-dimensional space. Essentially, this microphone records directional sound from all surrounding sources and encodes the spatial direction (think vectors). On playback with the right configuration of speakers, this gives a truly immersive aural experience. This is a superlative product – strongly recommended.

Derzeit das preiswerteste Ambisonic Mic
Dustin A. 13.09.2021
Ich habe mir das NT-SF1 zusammen mit dem Zoom F6 zugelegt um in die Welt des SPatial Recordings einzusteigen.
Wichtig ist, dass man alles im A-Format aufzeichnet, um es dann von dem Gratis Decoder VST Plugin von Rode in nahezu jedes erdenkliche decodieren zu lassen.
Von "mono" über "binaural" bis hin zu Atmos mit Höheninfomarionen ist hier alles möglich und klanglich gibt es nichts auszusetzen.

Beim Mikrofonieren von Instrumenten ist dennoch wichtig, eine gute Position in Relation zum Instrument zu nehmen, da trotz des 360° Radius ein diffuser Klang ensteht, wenn z.B. das Mikro höher positioniert ist, als die Gitarre.
Mit anderen Worten: Die bewährten Regeln des Recordings bestehen weiterhin, aber man kann jetzt nachträglich die Charakteristik ändern, oder ein Room Mic in Wide AB hinzufügen, wo keines war. Sehr nützlich.

Es soll nicht unerwähnt bleiben, dass das Plugin eine erhebliche Latenz hat, also ist das nichts für Echtzeitanwendungen. Man kann aber durchaus ohne Plugin monitoren und z.B. nur eine Kapsel durch den Monitor schicken, um dann später beim Mischen das Plugin einzuschleifen.
Der Beiliegende Windschutz ist unerlässlich für Außenaufnahmen.

Insgesamt habe ich also erhalten, was ich mir erhofft hatte.

Très bon micro pour les paysages sonores
Pierre Henry - 09.06.2021
J'utilise ce micro régulièrement, surtout pour des prises sons extérieures et les convertir en binaural, mais aussi pour faire des prises sons rapide de concerts. Attention si vous utilisez le micro avec un enregistreur portable (comme un Zoom H6), utilisez le avec un chargeur portable, car les 4 capsules requiert l'alimentation fantôme et les piles se décharge très vite.
La bonnette est efficace. Prenez soin de votre câble, il me parait un peu fragile, mais si vous êtes soigneux, il n'y aura pas de problèmes, le mien est en très bon état.
Microphone pratique et efficace, je ne pourrais plus m'en passer.

It's a trip!
fluteberlin 27.09.2019
Ich benutze das NT-SF1 für Fieldrecording und als zusätzliches Raummikrofon bei Musikaufnahmen, um die Raumantwort später kontrolliert zumischen zu können. Die SoundField-Software ist super.
Nicht irritieren lassen: erst wenn man eine Poly-Wav-Aufnahme in die DAW geladen hat, lässt sich das SoundField-PlugIn als VST öffnen.
