The AnalyserNodeinterface represents a node able to provide real-time frequency and time-domain analysis information. It is an AudioNode that passes the audio stream unchanged from the input to the output, but allows you to take the generated data, process it, and create audio visualizations.
AudioDestinationNode has no output (as it is the output, no more AudioNode can be linked after it in the audio graph) and one input. The amount of channels in the input must be between 0 and the maxChannelCount value or an exception is raised.
The ConvolverNode interface is an AudioNode that performs a Linear Convolution on a given AudioBuffer, often used to achieve a reverb effect. A ConvolverNode always has exactly one input and one output.
