The AudioNode interface and concrete types
Structs
AnalyserNode represents a node able to provide real-time frequency and
time-domain analysis information.Options for constructing an
AnalyserNodeAudioBufferSourceNode represents an audio source that consists of an
in-memory audio source (i.e. an audio file completely loaded in memory),
stored in an AudioBuffer.Options for constructing an
AudioBufferSourceNodeRepresenting the final audio destination and is what the user will ultimately hear.
BiquadFilterNode is an AudioNode processor implementing very common low-order
IIR filters.
Options for constructing a
BiquadFilterNodeConfig for up/down-mixing of input channels for audio nodes
Options that can be used in constructing all AudioNodes.
AudioNode for combining channels from multiple audio streams into a single audio stream.
Options for constructing a
ChannelMergerNodeAudioNode for accessing the individual channels of an audio stream in the routing graph
Options for constructing a
ChannelSplitterNodeAudio source whose output is nominally a constant value. A
ConstantSourceNode
can be used as a constructible AudioParam by automating the value of its offset.Options for constructing an
ConstantSourceNodeProcessing node which applies a linear convolution effect given an impulse response.
ConvolverNode optionsNode that delays the incoming audio signal by a certain amount
Options for constructing a
DelayNodeDynamicsCompressorNode provides a compression effect.Options for constructing a
DynamicsCompressorNodeAudioNode for volume control
Options for constructing a
GainNodeIIRFilterNode is an AudioNode processor implementing a general IIR
(infinite impulse response)Filter.
Options for constructing a
IIRFilterNodeAn audio source from an
<audio> elementOptions for constructing a
MediaElementAudioSourceNodeAn audio stream destination (e.g. WebRTC sink)
An audio source from a
MediaStream (e.g. microphone input)Options for constructing a
MediaStreamAudioSourceNodeOscillatorNode represents an audio source generating a periodic waveform.
It can generate a few common waveforms (i.e. sine, square, sawtooth, triangle),
or can be set to an arbitrary periodic waveform using a PeriodicWave object.Options for constructing an
OscillatorNodePannerNode positions / spatializes an incoming audio stream in three-dimensional space.Options for constructing a
PannerNodeStereoPannerNode positions an incoming audio stream in a stereo imageOptions for constructing a
StereoPannerOptionsWaveShaperNode allows to apply non-linear distortion effect on a audio
signal. Arbitrary non-linear shaping curves may be specified.WaveShaperNode optionsEnums
Biquad filter types
How channels must be matched between the node’s inputs and outputs.
The meaning of the channels, defining how audio up-mixing and down-mixing will happen.
Algorithm to reduce the volume of an audio source as it moves away from the listener
Type of the waveform rendered by an
OscillatorNodeenumerates the oversampling rate available for
WaveShaperNodeSpatialization algorithm used to position the audio in 3D space
Traits
This interface represents audio sources, the audio destination, and intermediate processing
modules.
Interface of source nodes, controlling start and stop times.
The node will emit silence before it is started, and after it has ended.
