Renderer
The Renderer plug-in transforms any input signal to any desired output format. When set to binaural, it renders the input signal to a stereo output, suitable for headphone listening. When downmixing the input to loudspeaker signals, it provides adjustable downmixing filters for rear and height channels to simulate sounds coming from behind or above the listener.
Parameters
Output Format and Platform Options
This sets the output format of the rendering. The options include the following:
- Channel-based formats (from stereo up to 7.1.4)
- Binaural output (for headphone playback)
- Platform setting (determined by the current project platform's speaker mode)
Platform
If Platform is selected as the output format, the actual format is determined by the currently set output format. This is useful if you want to support different output formats, e.g. let the user select between surround and binaural audio output. Please see the Output Format Selection Guide for an in-depth explanation.
2Ch -> Binaural
As Stereo and Binaural formats both use two channels, the Renderer will need
additional information to determine which format to use. This information is
provided by the Platform Options parameter. With the 2Ch -> Binaural option
enabled, the Renderer will render binaural signals if the project platforms
speaker mode is set to stereo. This switch can be automated by an FMOD
parameter, so you can switch between stereo and binaural from your game
settings.
Down-mixing Options
The downmixing sections provides two filters to simulate rear and height channels in downmixing scenarios.
Height Filter
The height filter simulates sounds coming from above the listener in layouts without height channels. The parameter controls the intensity of the height effect.
Rear Filter
The rear filter simulates sounds coming from behind the listener in layouts without rear channels. The parameter controls the intensity of the rear effect.
