AudioParam class
The Web Audio API's interface represents an audio-related
parameter, usually a parameter of an AudioNode (such as
GainNode.gain).
An can be set to a specific value or a change in value, and can
be scheduled to happen at a specific time and following a
specific pattern.
Each has a list of events, initially empty, that define when and
how values change. When this list is not empty, changes using the
AudioParam.value attributes are ignored. This list of events
allows us to schedule changes that have to happen at very precise
times, using arbitrary timeline-based automation curves. The time
used is the one defined in AudioContext.currentTime.
