AudioNode

The AudioNode interface is a generic interface for representing an audio processing module like an audio source (e.g. an HTML <audio> or <video> element, an OscillatorNode, etc.), the audio destination, intermediate processing module (e.g. a filter like BiquadFilterNode or ConvolverNode), or volume control (like GainNode).

AudioNode.connect(AudioNode)

A reference to the destination AudioNode object. In some browsers older implementations of this interface return void.

AudioNode.connect(AudioParam)

It is possible to connect an AudioNode output to more than one AudioParam, and more than one AudioNode output to a single AudioParam, with multiple calls to connect(). Fan-in and fan-out are therefore supported.

AudioParam.exponentialRampToValueAtTime()

A reference to this AudioParam object. In some browsers older implementations of this interface return void.

AudioParam.setTargetAtTime()

The change starts at the time specified in startTime and exponentially moves towards the value given by the target parameter. The exponential decay rate is defined by the timeConstant parameter. This is the time it takes a first-order linear continuous time-invariant system to reach the value 1 - 1/e (around 63.2%) given a step input response (transition from 0 to 1 value): basically, the larger it is, the slower the transition will be.  This is useful for decay or release portions of envelopes.

AudioParam.value

 Though value can be set, any modifications happening while there are automation events scheduled — that is, events scheduled using the methods of the AudioParam — are ignored, without raising any exception.
