The AudioParamMap interface of the Web Audio API represents an iterable and read-only set of multiple audio parameters.
An AudioParamMap instance is a read-only Map-like object, in which each key is the name string for a parameter, and the corresponding value is an AudioParam containing the value of that parameter.
The following methods are available to all read-only Map-like objects (the below links are to the Map global object reference page).
size
Returns the number of entries in the map.
