/DOMDelayNode
The DelayNode interface represents a delay-line; an AudioNode audio-processing module that causes a delay between the arrival of an input data and its propagation to the output. A DelayNode always has exactly one input and one output, both with the same amount of channels.
When creating a graph that has a cycle, it is mandatory to have at least one DelayNode in the cycle, or the nodes taking part in the cycle will be muted.
