|index||Zero-based index of user-defined parameter to be set.|
|value||New value of the user-defined parameter.|
bool True, if the parameter could be set.
Sets a user-defined parameter of a custom ambisonic decoder effect that is attached to an AudioSource.
Since this is for internal use in custom inspectors controlling custom ambisonic decoder effects implemented as native audio plugins, it is up to the decoder to perform necessary clipping on the UI and native sides through the setparameter/getparameter callbacks of the native audio plugin.
