AmbisonicRenderer

The AmbisonicRenderer renders first-order Ambisonics (FOA) soundfields to binaural audio. The plug-in expects a 4-channel input layout (Quad) with the Ambisonics signal in ambix format (ACN channel order, SN3D normalization). It will then output a stereo signal holding the binaural rendering of the soundfield.

Parameters

Headlocked

When enabled, the sound source will be locked to the listener’s head, meaning that the soundfield’s rendering will be independent of the listener’s rotation, only on the source’s position and rotation.

Distance Attenuation

The Distance Attenuation section has three parameters, Type, Min Distance and Max Distance.

Type lets you choose the relationship between distance and output attenuation. Choices are inverse square law, linear, logarithmic and tapered logarithmic relationships. Additionally, distance attenuation can be turned off alltogether. To understand how the various distance models work, have a look at the FMOD documentation:

• 3D sounds white paper ↗ 
• Core API documentation ↗ 

Min Distance lets you choose at which distance from the source the attenuation model starts to kick in.

Max Distance is the distance at which the maximum attenuation (-80dB) is reached.

Note that the values for Min Distance and Max Distance set in the AmbisonicRenderer are only used if the Override option is enabled. If Override is disabled, the AmbisonicRenderer will use the event macro distance range and ignore the Min Distance and Max Distance values specified in the plug-in.
