// ScriptProcessorNode is an AudioNode which allows for arbitrary synthesis or
// processing directly using JavaScript.  The API allows for a variable number
// of inputs and outputs, although it must have at least one input or output.
// This basic implementation supports no more than one input and output.  The
// "onaudioprocess" attribute is an event listener which will get called
// periodically with an AudioProcessingEvent which has AudioBuffers for each
// input and output.
