Add sound to your virtual reality video / spherical 360° content with the Sennheiser Ambeo Vitual Reality (VR) Microphone. The easy-to-use ambisonic microphone features four matched KE 14 capsules in a tetrahedral arrangement. Ambisonics is a multi-channel technique which means you can capture the audio surrounding a single point, in this case wherever you place the Ambeo VR microphone.
Playback representation of ambisonics is rendered binaurally so you can virtually rotate the orientation of the perspective both horizontally and vertically. All the post playback tools support this technique. In addition Sennheiser, via theVR Creators Program, involved industry professionals while developing the Ambeo VR Microphone.
They also developed A-B encoder software which functions as a plug-in. The Ambeo VR Microphone delivers A-format which is a raw 4-channel output which you can convert into a new set of 4-channel known as the Ambisonics B-format. B-format is a W, X, Y, Z representation of the sound field around the microphone where W equals the sum of all 4 capsules. X, Y, and Z represent the bi-directional microphone patters as front/back, left/right, and up/down, respectively. In this fashion, you can audition Ambisonics B in playback.
The plugin (which you can download for free) is available for both MAC and Windows for VST, AU, and AAX format.
