Directivity

The Directivity node defines a sound source’s directivity pattern, which determines how the sound is distributed in space. The output can be connected to the Spatializer node.

The directivity pattern is defined by the inner and outer angles, outer gain, and outer low-pass setting.

The Inner Angle defines the angular spread around the frontal direction where sound is emitted without attenuation. The Outer Angle defines the angular spread around the frontal direction outside of which sound is attenuated according to the Outer Gain and Outer Low-Pass parameters. In between the inner and the outer angle, the attenuation is linearly interpolated / blended.

The Outer Gain is a value between -80dB and 0dB, where -80dB means that the sound is completely attenuated and 0dB means that the sound is not attenuated at all. The Outer Low-Pass is a value between 0% and 100% controlling the intensity of the low-pass filter, where 0% means that the sound is not filtered at all and 100% means that the sound is completely filtered.
