 // 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.
