Web Audio API | AudioNode numberOfInputs Property

The AudioNode.numberOfInputs property is used to return the number of inputs that are feeding the node. The Source node is used to define as nodes that contain a numberOfInputs property with a value zero.

Syntax:

var numInputs = audioNode.numberOfInputs;

Return Value: It returns an integer value greater than equal to zero.
