3DIO Omni Binaural Microphone
The 3DIO Omni Binaural Microphone is a four-position binaural perspective array of eight Primo EM172 microphone capsules to create a 360 degree audio environment. The eight capsules are paired up to make 4 pairs of ears angled at 0, 90, 180 and 270 degrees, allowing you can use all the ears for 360 degree recording or use one pair of ears for a standard binaural recording.
The Omni Binaural microphone is ideally suited for adding immersive binaural audio to your 360 degree video production. The Omni Binaural mic can also be used to provide binaural localization/orientation freedom for audio engineers. Simply place the mic where you want it, hit record, and binaurally/positionally mix your audio sources in post.
Synchronising Omni Binaural audio to a 360 video during playback only requires a simple volume control script. This is typically implemented in a custom VR video player app. This particular script works directly with Unity for demonstration purposes, but can easily be ported to any other language that supports audio playback with volume control. The script plays all 4 Omni stereo binaural tracks in sync, while adjusting the volume of each based on the user's head azimuth rotation angle.

The Omni Binaural microphone comes standard with 8 Primo EM172 microphone capsules.
The Omni binaural microphone comes standard with a 5/8" microphone stand adapter installed in the base. The microphone stand adapter is removable. The base of the microphone has a 1/4"-20 female thread mounting hole that can be connected to a hot-shoe adapter or used to mount directly onto a tripod or grip handle.

The output of the Omni Binaural mic is a set of four 5-pin XLR connectors. Each connector is associated with the ears to the respective left and right. You can use splitter cables (not included) to break out the left/right signals to connect to your 8-channel preamp, or to 4 individual audio recorders. The outputs of the Omni Binaural microphone are true transformer-balanced, phantom powered 5-pin stereo XLR outputs.
