The AnalyserNode interface represents a node able to provide
frequency and time-domain analysis information. It is an `web.audio.AudioNode`
passes the audio stream unchanged from the input to the output,
allows you to take the generated data, process it, and create
visualizations.

The AudioBuffer interface represents a short audio asset residing
memory, created from an audio file using the `AudioContext.decodeAudioData()`
or from raw data using `AudioContext.createBuffer()`. Once put
an AudioBuffer, the audio can then be played by being passed
an `web.audio.AudioBufferSourceNode`.

The AudioBufferSourceNode interface is an `web.audio.AudioScheduledSourceNode`
represents an audio source consisting of in-memory audio data,
in an `web.audio.AudioBuffer`. It's especially useful for playing
audio which has particularly stringent timing accuracy requirements,
as for sounds that must match a specific rhythm and can be kept
memory rather than being played from disk or the network.

The AudioContext interface represents an audio-processing graph
from audio modules linked together, each represented by an `web.audio.AudioNode`.

The AudioContextOptions dictionary is used to specify configuration
when constructing a new `web.audio.AudioContext` object to represent
graph of web audio nodes.

AudioDestinationNode has no output (as it is the output, no more
can be linked after it in the audio graph) and one input. The
of channels in the input must be between 0 and the maxChannelCount
or an exception is raised.

The AudioListener interface represents the position and orientation
the unique person listening to the audio scene, and is used in
spatialization. All `web.audio.PannerNode`s spatialize in relation
the AudioListener stored in the `BaseAudioContext.listener` attribute.

The AudioNode interface is a generic interface for representing
audio processing module. Examples include:

The Web Audio API's AudioParam interface represents an audio-related
usually a parameter of an `web.audio.AudioNode` (such as `GainNode.gain`).

The AudioParamDescriptor dictionary of the Web Audio API specifies
for an `web.audio.AudioParam` objects.

The Web Audio API interface AudioParamMap represents a set of
audio parameters, each described as a mapping of a `web.DOMString`
the parameter to the `web.audio.AudioParam` object representing
value.

The AudioScheduledSourceNode interface—part of the Web Audio
a parent interface for several types of audio source node interfaces
share the ability to be started and stopped, optionally at specified
Specifically, this interface defines the `start()` and `stop()`
as well as the `onended` event handler.

AudioScheduledSourceNode Events.

The AudioWorkletGlobalScope interface of the Web Audio API represents
global execution context for user-supplied code, which defines
`web.audio.AudioWorkletProcessor`-derived classes. Each `web.audio.BaseAudioContext`
a single `web.audio.AudioWorklet` available under the `audioWorklet`
which runs its code in a single AudioWorkletGlobalScope.

The AudioWorkletNode interface of the Web Audio API represents
base class for a user-defined `web.audio.AudioNode`, which can
connected to an audio routing graph along with other nodes. It
an associated `web.audio.AudioWorkletProcessor`, which does the
audio processing in a Web Audio rendering thread.

The AudioWorkletNodeOptions dictionary of the Web Audio API is
to specify configuration options when constructing a new `web.audio.AudioWorkletNode`
for custom audio processing.

The AudioWorkletProcessor interface of the Web Audio API represents
audio processing code behind a custom `web.audio.AudioWorkletNode`.
lives in the `web.audio.AudioWorkletGlobalScope` and runs on
Web Audio rendering thread. In turn, an `web.audio.AudioWorkletNode`
on it runs on the main thread.

The BaseAudioContext interface of the Web Audio API acts as a
definition for online and offline audio-processing graphs, as
by `web.audio.AudioContext` and `web.audio.OfflineAudioContext`

The BiquadFilterNode interface represents a simple low-order
and is created using the `AudioContext.createBiquadFilter()`
It is an `web.audio.AudioNode` that can represent different kinds
filters, tone control devices, and graphic equalizers.

The ConstantSourceNode interface—part of the Web Audio API—represents
audio source (based upon `web.audio.AudioScheduledSourceNode`)
output is single unchanging value. This makes it useful for cases
which you need a constant value coming in from an audio source.
addition, it can be used like a constructible `web.audio.AudioParam`
automating the value of its `offset` or by connecting another
to it; see Controlling multiple parameters with ConstantSourceNode.

The ConvolverNode interface is an `web.audio.AudioNode` that
a Linear Convolution on a given `web.audio.AudioBuffer`, often
to achieve a reverb effect. A ConvolverNode always has exactly
input and one output.

web.audio interfaces.

The DelayNode interface represents a delay-line; an `web.audio.AudioNode`
module that causes a delay between the arrival of an input data
its propagation to the output.

Inherits properties from its parent, `web.audio.AudioNode`.

The GainNode interface represents a change in volume. It is an
audio-processing module that causes a given gain to be applied
the input data before its propagation to the output. A GainNode
has exactly one input and one output, both with the same number
channels.

The IIRFilterNode interface of the Web Audio API is a `web.audio.AudioNode`
which implements a general infinite impulse response (IIR) filter;
type of filter can be used to implement tone control devices
graphic equalizers as well. It lets the parameters of the filter
be specified, so that it can be tuned as needed.

Inherits properties from its parent, `web.audio.AudioNode`.

The MediaStreamAudioSourceNode interface is a type of `web.audio.AudioNode`
operates as an audio source whose media is received from a `web.streams.MediaStream`
using the WebRTC or Media Capture and Streams APIs.

The MediaStreamAudioSourceOptions dictionary provides configuration
used when creating a `web.audio.MediaStreamAudioSourceNode` using
constructor.

The MediaStreamTrackAudioSourceOptions dictionary is used when
options to the `MediaStreamTrackAudioSourceNode()` constructor.

The Web Audio API OfflineAudioCompletionEvent interface represents
that occur when the processing of an `web.audio.OfflineAudioContext`
terminated. The complete event implements this interface.

The OfflineAudioContext interface is an `web.audio.AudioContext`
representing an audio-processing graph built from linked together
In contrast with a standard `web.audio.AudioContext`, an OfflineAudioContext
render the audio to the device hardware; instead, it generates
as fast as it can, and outputs the result to an `web.audio.AudioBuffer`.

OfflineAudioContext Events.

The OscillatorNode interface represents a periodic waveform,
as a sine wave. It is an `web.audio.AudioScheduledSourceNode`
module that causes a specified frequency of a given wave to be
effect, a constant tone.

A PannerNode always has exactly one input and one output: the
can be mono or stereo but the output is always stereo (2 channels);
can't have panning effects without at least two audio channels!

The `pan` property takes a unitless value between -1 (full left
and 1 (full right pan). This interface was introduced as a much
way to apply a simple panning effect than having to use a full

A WaveShaperNode always has exactly one input and one output.
