Tone.AutoWah
↳ EXTENDS Tone.EffectTone.AutoWah connects a Tone.Follower to a bandpass filter (Tone.Filter). The frequency of the filter is adjusted proportionally to the incoming signal’s amplitude. Inspiration from Tuna.js.
CONSTRUCTOR
new Tone.AutoWah ( [The frequency the filter is set to at the low point of the wah
The number of octaves above the baseFrequency the filter will sweep to when fully open
The decibel threshold sensitivity for the incoming signal. Normal range of -40 to 0.
DEFAULTS
EXAMPLE
var autoWah = new Tone.AutoWah(50, 6, -30).toMaster();
//initialize the synth and connect to autowah
var synth = new Synth.connect(autoWah);
//Q value influences the effect of the wah - default is 2
autoWah.Q.value = 6;
//more audible on higher notes
synth.triggerAttackRelease("C4", "8n")Members
.sensitivity
↝ Decibels #The sensitivity to control how responsive to the input signal the filter is.
.context
↝ Tone.Context READONLY #Get the audio context belonging to this instance.
.numberOfInputs
↝ Number READONLY #The number of inputs feeding into the AudioNode. For source nodes, this will be 0.
.numberOfOutputs
↝ Number READONLY #The number of outputs coming out of the AudioNode.
.channelCount
↝ Number READONLY #channelCount is the number of channels used when up-mixing and down-mixing connections to any inputs to the node. The default value is 2 except for specific nodes where its value is specially determined.
.channelCountMode
↝ String READONLY #channelCountMode determines how channels will be counted when up-mixing and down-mixing connections to any inputs to the node. The default value is “max”. This attribute has no effect for nodes with no inputs.
.channelInterpretation
↝ String READONLY #channelInterpretation determines how individual channels will be treated when up-mixing and down-mixing connections to any inputs to the node. The default value is “speakers”.
.wet
↝ NormalRange #The wet control is how much of the effected will pass through to the output. 1 = 100% effected signal, 0 = 100% dry signal.
Methods
.chain ( )
#this
Connect the output of this node to the rest of the nodes in series.
EXAMPLE
//connect a node to an effect, panVol and then to the master output
node.chain(effect, panVol, Tone.Master);
.connect ( )
#optionally which output to connect from
optionally which input to connect to
this
connect the output of a ToneNode to an AudioParam, AudioNode, or ToneNode
.disconnect ( )
#Either the output index to disconnect if the output is an array, or the node to disconnect from.
this
disconnect the output
.fan ( )
#this
connect the output of this node to the rest of the nodes in parallel.
.toMaster ( )
#this
Connect ‘this’ to the master output. Shorthand for this.connect(Tone.Master)
EXAMPLE
//connect an oscillator to the master output
var osc = new Tone.Oscillator().toMaster();
