Tone.Filter
↳ EXTENDS Tone.AudioNodeTone.Filter is a filter which allows for all of the same native methods as the BiquadFilterNode. Tone.Filter has the added ability to set the filter rolloff at -12 (default), -24 and -48.
CONSTRUCTOR
new Tone.Filter ( [DEFAULTS
EXAMPLE
var filter = new Tone.Filter(200, "highpass");Members
.type
↝ string #The type of the filter. Types: “lowpass”, “highpass”, “bandpass”, “lowshelf”, “highshelf”, “notch”, “allpass”, or “peaking”.
.rolloff
↝ number #The rolloff of the filter which is the drop in db per octave. Implemented internally by cascading filters. Only accepts the values -12, -24, -48 and -96.
.numberOfInputs
↝ Number READONLY #The number of inputs feeding into the AudioNode. For source nodes, this will be 0.
.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”.
.context
↝ Tone.Context READONLY #Get the audio context belonging to this instance.
.numberOfOutputs
↝ Number READONLY #The number of outputs coming out of the AudioNode.
Methods
.getFrequencyResponse ( )
#The number of values to return
The frequency response curve between 20-20k
Get the frequency response curve. This curve represets how the filter responses to frequencies between 20hz-20khz.
.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();
