     *     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.
