Tone.PitchShift

↳ EXTENDS Tone.FeedbackEffect

Tone.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 ( [
pitch
] )
pitch

The interval to transpose the incoming signal by.

optional

DEFAULTS

{
pitch : 0 ,
windowSize : 0.1 ,
delayTime : 0 ,
feedback : 0
}

Members

.delayTime

Time #

The amount of delay on the input signal

</>

.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
</>

.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;

.context

Tone.Context READONLY #

Get the audio context belonging to this instance.

inherited from Tone.Effect

.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.

.toMaster ( )

#
↪ returns Tone.AudioNode

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();
