WaveShaperNode is an AudioNode processor implementing non-linear distortion effects.
Non-linear waveshaping distortion is commonly used for both subtle non-linear warming, or more obvious distortion effects. Arbitrary non-linear shaping curves may be specified.
numberOfInputs : 1 numberOfOutputs : 1
The AudioContext which owns this AudioNode.
The shaping curve used for the waveshaping effect. The input signal is nominally within the range -1 -> +1. Each input sample within this range will index into the shaping curve with a signal level of zero corresponding to the center value of the curve array. Any sample value less than -1 will correspond to the first value in the curve array. Any sample value less greater than +1 will correspond to the last value in the curve array.
The number of inputs feeding into the AudioNode. This will be 0 for an AudioSourceNode.
The number of outputs coming out of the AudioNode. This will be 0 for an AudioDestinationNode.
Connects the AudioNode to another AudioNode.
It is possible to connect an AudioNode output to more than one input with multiple calls to connect(). Thus, "fanout" is supported.
It is possible to connect an AudioNode to another AudioNode which creates a cycle. In other words, an AudioNode may connect to another AudioNode, which in turn connects back to the first AudioNode. This is allowed only if there is at least one DelayNode in the cycle or an exception will be thrown.
There can only be one connection between a given output of one specific node and a given input of another specific node. Multiple connections with the same termini are ignored. For example:
nodeA.connect(nodeB);
nodeA.connect(nodeB);
will have the same effect as
nodeA.connect(nodeB);
the AudioNode to connect to.
an index describing which output of the AudioNode from which to connect. An out-of-bound value throws an exception.
an index describing which input of the destination AudioNode to connect to. An out-of-bound value throws an exception.
Connects the AudioNode to an AudioParam, controlling the parameter value with an audio-rate signal.
It is possible to connect an AudioNode output to more than one AudioParam with multiple calls to connect(). Thus, "fanout" is supported.
It is possible to connect more than one AudioNode output to a single AudioParam with multiple calls to connect(). Thus, "fanin" is supported.
An AudioParam will take the rendered audio data from any AudioNode output connected to it and convert it to mono by down-mixing if it is not already mono, then mix it together with other such outputs and finally will mix with the intrinsic parameter value (the value the AudioParam would normally have without any audio connections), including any timeline changes scheduled for the parameter.
There can only be one connection between a given output of one specific node and a specific AudioParam. Multiple connections with the same termini are ignored. For example:
nodeA.connect(param);
nodeA.connect(param);
will have the same effect as
nodeA.connect(param);
the AudioParam to connect to.
an index describing which output of the AudioNode from which to connect. An out-of-bound value throws an exception.
Disconnects an AudioNode's output.
an index describing which output of the AudioNode to disconnect. An out-of-bound value throws an exception.
