BiquadFilterNode extension type

The BiquadFilterNode interface represents a simple low-order filter, and is created using the BaseAudioContext/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.

Number of inputs 1
Number of outputs 1
Channel count mode "max"
Channel count 2 (not used in the default count mode)
Channel interpretation "speakers"

Methods

addEventListener(String type, EventListener? callback, [JSAny options]) → void
The addEventListener() method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.
inherited
connect(JSObject destinationNodeOrDestinationParam, [int output, int input]) → AudioNode?
The connect() method of the AudioNode interface lets you connect one of the node's outputs to a target, which may be either another AudioNode (thereby directing the sound data to the specified node) or an AudioParam, so that the node's output data is automatically used to change the value of that parameter over time.
inherited
disconnect([JSAny destinationNodeOrDestinationParamOrOutput, int output, int input]) → void
The disconnect() method of the AudioNode interface lets you disconnect one or more nodes from the node on which the method is called.
inherited
dispatchEvent(Event event) → bool
The dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) also apply to events dispatched manually with dispatchEvent().
inherited
getFrequencyResponse(JSFloat32Array frequencyHz, JSFloat32Array magResponse, JSFloat32Array phaseResponse) → void
The getFrequencyResponse() method of the BiquadFilterNode interface takes the current filtering algorithm's settings and calculates the frequency response for frequencies specified in a specified array of frequencies.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
removeEventListener(String type, EventListener? callback, [JSAny options]) → void
The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener from the target. The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
