Tone.PitchShift
↳ EXTENDS Tone.FeedbackEffectTone.PitchShift does near-realtime pitch shifting to the incoming signal. The effect is achieved by speeding up or slowing down the delayTime of a DelayNode using a sawtooth wave. Algorithm found in this pdf. Additional reference by Miller Pucket.
CONSTRUCTOR
new Tone.PitchShift ( [The interval to transpose the incoming signal by.
DEFAULTS
Members
.windowSize
↝ Time #The window size corresponds roughly to the sample length in a looping sampler. Smaller values are desirable for a less noticeable delay time of the pitch shifted signal, but larger values will result in smoother pitch shifting for larger intervals. A nominal range of 0.03 to 0.1 is recommended.
EXAMPLE
pitchShift.windowSize = 0.1;.pitch
↝ Interval #Repitch the incoming signal by some interval (measured in semi-tones).
EXAMPLE
pitchShift.pitch = -12; //down one octave
pitchShift.pitch = 7; //up a fifth.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.
.feedback
↝ NormalRange #The amount of signal which is fed back into the effect input.
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();
