==Introduction==

AMBEO VR Microphone is a 3-dimensional audio recording device developed by the German Company Sennheiser. The virtual reality microphone is designed to provide a convincing recording of the 360-degree sound space. Sennheiser introduced AMBEO VR Mic to the world at CES 2017 in Las Vegas. The makers have fixed the price of an AMBEO VR Mic at $1700.

AMBEO VR Microphone is a 3-dimensional audio recording device developed by the German Company [[Sennheiser]]. The [[virtual reality]] microphone is designed to provide a convincing recording of the 360-degree sound space. Sennheiser introduced AMBEO [[VR]] Mic to the world at [[CES 2017]] in Las Vegas. The makers have fixed the price of an AMBEO VR Mic at $1700.

==Ambisonics==

Ambisonics is the best suited audio technology used for virtual reality, 3D sound, and interactive audio applications. Apart from the horizontal plane, the Ambisonics technology captures audio from above and below from a single point (for example, a listener). In the case of ambisonics, speaker signals are not carried through the transmission channels. Here, the sound is in the B-format, which is independent of the speaker. This format is then later interpreted to the speaker setup. This variation or divergence helps the Ambisonics technology improve the richness of sound.

==How the AMBEO VR Mic Works?==

The tetrahedral structure made up of four capsules captures and delivers the sound in A-format, which is a raw 4-channel output. Listeners can’t use the audio as such. The A-format needs to be changed to Ambisonics B-format, which is another 4-channel format. In AMBEO the conversion is performed by the A-B format converter plug-in. The plug-in can be downloaded in AAX, AU, and VST and used in a Mac DAW or Windows PC.

Here is how the B-format works? The B-format technique takes a 4-way image of the audio field around the microphone. The image comprises of W, X, Y, and Z; here X, Y, and Z represent the microphone pattern that corresponds to front/back, left/right, and up/down. The W, on the other hands, is the combination of all four capsules. This way, sound from any direction of the microphone can be exactly captured and reproduced for the benefit of a listener.
