+   *     coneOuterGain - (0 by default) A parameter for directional audio sources, this is the gain outside of the
+   *                     `coneOuterAngle`. It is a linear value in the range `[0, 1]`.
+   *     distanceModel - ('inverse' by default) Determines algorithm used to reduce volume as audio moves away from
+   *                     listener. Can be `linear`, `inverse` or `exponential.
+   *     maxDistance - (10000 by default) The maximum distance between source and listener, after which the volume
+   *                   will not be reduced any further.
+   *     refDistance - (1 by default) A reference distance for reducing volume as source moves further from the listener.
+   *                   This is simply a variable of the distance model and has a different effect depending on which model
+   *                   is used and the scale of your coordinates. Generally, volume will be equal to 1 at this distance.
+   *     rolloffFactor - (1 by default) How quickly the volume reduces as source moves from listener. This is simply a
+   *                     variable of the distance model and can be in the range of `[0, 1]` with `linear` and `[0, ∞]`
+   *                     with `inverse` and `exponential`.
+   *     panningModel - ('HRTF' by default) Determines which spatialization algorithm is used to position audio.
+   *                     Can be `HRTF` or `equalpower`.
+   *
