Tone.FFT
↳ EXTENDS Tone.AudioNodeGet the current frequency data of the connected audio source using a fast Fourier transform.
CONSTRUCTOR
new Tone.FFT ( [The size of the FFT. Value must be a power of two in the range 16 to 16384.
DEFAULTS
Members
.size
↝ Number #The size of analysis. This must be a power of two in the range 16 to 16384. Determines the size of the array returned by getValue (i.e. the number of frequency bins). Large FFT sizes may be costly to compute.
.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.
.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.
Methods
.getValue ( )
#Gets the current frequency data from the connected audio source. Returns the frequency data of length size as a Float32Array of decibel values.
.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();
