SoundRenderer

SoundRenderer is a spatialized audio rendering plugin for Maya to simulate 3D-positional audio. It can be used to create a multichannel audiotrack from many mono wav-files positioned in the scene for later synchronization with the rendered video.
The plugin uses the audiofiles set up in the 3d scene and renders them to a variable number of channels. To simulate a realistic surrounding, it uses several realworld effects:

distance-delay
doppler-effect
air-absorption
panning

Nodes

There are two different kinds of nodes available. The speaker nodes can be linked to wav-files which are triggered either by a keyframe or an expression, but can also be looped. The listener node can contain a variable number of speakers and offers a customization of the different effects and their precision.

Mixer

The mixer offers a parallel configuration of the Speakers in the scene without having to find and select them. It also allows to change the triggering mode.
