DelayNode

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.

The DelayNode acts as a delay-line, here with a value of 1s.

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.

Number of inputs 1
Number of outputs 1
Channel count mode "max"
Channel count 2 (not used in the default count mode)
Channel interpretation "speakers"
