3Dio Omni Binaural Microphone

3Dio Omni Binaural Microphone

The 3Dio Omni Binaural Microphone is an Omni Binaural microphone that consists of 4 pairs of ears, each pointed at 90 degrees from the adjacent pair. This provides a single point, 4-position binaural perspective of any audio environment.

The 3Dio Omni Binaural microphone requires four, 5-pin to dual 3-pin XLR cables, such as the Rode NT4-DXLR cables.

The Omni Binaural mic captures stereo binaural audio from 4 different directions. 0 degrees, 90, 180, and 270 degrees, corresponding to the 4 different binaural angles (ear pairs) around the microphone. The microphone is an 8-channel microphone, but it is useful to edit and mix the output of the microphone in 4 pairs of stereo binaural tracks. 90 degrees being clockwise, or 3 o’clock.

Synchronizing Omni Binaural audio to a 360 video during playback only requires a simple volume control script, which is provided for download HERE (a Unity example in C#). 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 user essentially only hears a blend of 2 of the 4 tracks at any given time. The script crossfades between the Omni binaural tracks using an equal power crossfade algorithm. The download zip file also includes some example Omni binaural tracks to test with.

To record the output of the Omni microphone, we recommend an 8 channel recorder with 48V phantom power on each channel.

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.

Microphone Capsules
The Omni Binaural microphone comes standard with 8 microphone capsules.

Mounting
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.

Outputs
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.
