Is a k-rate AudioParam, a double representing a Q factor, or quality factor.
The EventTarget.addEventListener() method registers the specified listener on the EventTarget it's called on.
The EventTarget.addEventListener() method registers the specified listener on the EventTarget it's called on. The event target may be an Element in a document, the Document itself, a Window, or any other object that supports events (such as XMLHttpRequest).

Represents an integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node.
Represents an integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node. Its usage and precise definition depend on the value of AudioNode.channelCountMode.
Represents an enumerated value describing the way channels must be matched between the node's inputs and outputs.
Represents an enumerated value describing the way channels must be matched between the node's inputs and outputs.
Represents an enumerated value describing the meaning of the channels.
Represents an enumerated value describing the meaning of the channels. This interpretation will define how audio up-mixing and down-mixing will happen.
The possible values are "speakers" or "discrete".
Allows us to connect one output of this node to one input of an audio parameter.
Allows us to connect one output of this node to one input of an audio parameter.
Allows us to connect one output of this node to one input of another node.
Allows us to connect one output of this node to one input of another node.
Returns the associated AudioContext, that is the object representing the processing graph the node is participating in.

Is an a-rate AudioParam representing detuning of the frequency in cents.
Allows us to disconnect the current node from another one it is already connected to.
Allows us to disconnect the current node from another one it is already connected to.
The index describing which output of the AudioNode is going to be disconnected.
Dispatches an Event at the specified EventTarget, invoking the affected EventListeners in the appropriate order.
Dispatches an Event at the specified EventTarget, invoking the affected EventListeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) apply to events dispatched manually with dispatchEvent().

Is a k-rate AudioParam, a double representing a frequency in the current filtering algorithm measured in hertz (Hz).
Is a k-rate AudioParam, a double representing the gain used in the current filtering algorithm.
From the current filter parameter settings this method calculates the frequency response for frequencies specified in the provided array of frequencies.
From the current filter parameter settings this method calculates the frequency response for frequencies specified in the provided array of frequencies.
A Float32Array containing hertz values that you want the frequency response for.
A Float32Array that will contain the outputted magnitude of the frequency response for each inputted frequency (hertz) value. The magnitude values are unitless.
A Float32Array that will contain the outputted phase of the frequency response for each inputted frequency (hertz) value, measured in radians.
Returns the number of inputs feeding the node.
Returns the number of inputs feeding the node. Source nodes are defined as nodes having a numberOfInputs property with a value of 0.
Returns the number of outputs coming out of the node.
Returns the number of outputs coming out of the node. Destination nodes — like AudioDestinationNode — have a value of 0 for this attribute.
Removes the event listener previously registered with EventTarget.addEventListener.

Is a string value defining the kind of filtering algorithm the node is implementing.
The BiquadFilterNode interface represents a simple low-order filter, and is created using the AudioContext.createBiquadFilter() method. It is an AudioNode that can represent different kinds of filters, tone control devices, and graphic equalizers. A BiquadFilterNode always has exactly one input and one output.
