The AMBEO VR Mic makes capturing real spatial sound as simple as any stereo recording. You don’t need to set up several microphones – saving you time, money and manpower. Furthermore, using the AMBEO VR Mic means you’ll never have to add other sounds in the mix anymore to achieve stunning 3D sound.
Ambisonics is a multi-channel technique that lets you spherically capture the sound arriving from all directions, at a single point in space. For playback this representation is rendered binaurally, allowing you to virtually rotate the orientation of the perspective in all directions, horizontally and vertically. Ambisonics is supported by all of the major post-production and playback tools on the market today. This makes ambisonics the appropriate tool for Virtual Reality and all other applications involving 3D sound. A tool to create new worlds of sound with.
The capsules of the Sennheiser AMBEO VR Mic deliver A-format, a raw 4-channel output that has to be converted into a new set of 4 channels, the Ambisonics B-format. This is done by the specifically designed Sennheiser AMBEO A-B format converter plugin, which is available as free download for VST, AU and AAX format for your preferred Digital Audio Workstation for both PC and Mac. B-format is a W, X, Y, Z representation of the sound field around the microphone. W being the sum of all 4 capsules, whereas X, Y and Z are three virtual bi-directional microphone patterns representing front/back, left/right and up/down. Thus, any direction from the microphone can be auditioned by the listener during playback of Ambisonics B.
