Tone.Meter

↳ EXTENDS Tone.AudioNode

Tone.Meter gets the RMS of an input signal. It can also get the raw value of the input signal.

CONSTRUCTOR

new Tone.Meter (
smoothing
)
smoothing

The amount of smoothing applied between frames.

type: Number

DEFAULTS

{
smoothing : 0.8
}

EXAMPLE

var meter = new Tone.Meter();
var mic = new Tone.UserMedia().open();
//connect mic to the meter
mic.connect(meter);
//the current level of the mic input in decibels
var level = meter.getLevel();

Members

.smoothing

Number #

A value from 0 -> 1 where 0 represents no time averaging with the last analysis frame.

</>
inherited from Tone.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.

</>
inherited from Tone.AudioNode

.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.

</>
inherited from Tone.AudioNode

.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”.

</>
inherited from Tone.AudioNode

.context

Tone.Context READONLY #

Get the audio context belonging to this instance.

</>
inherited from Tone.AudioNode

.numberOfInputs

Number READONLY #

The number of inputs feeding into the AudioNode. For source nodes, this will be 0.

</>
inherited from Tone.AudioNode

.numberOfOutputs

Number READONLY #

The number of outputs coming out of the AudioNode.

</>

Methods

.getLevel ( )

#
↪ returns Decibels

Get the current decibel value of the incoming signal

</>

.getValue ( )

#
↪ returns Number

Get the signal value of the incoming signal

</>

.dispose ( )

#
↪ returns Tone.Meter

this

Clean up.

.fan ( )

#
nodes
↪ returns Tone.AudioNode

this

connect the output of this node to the rest of the nodes in parallel.

</>
inherited from Tone.AudioNode

.chain ( )

#
nodes
↪ returns Tone.AudioNode

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);
 
</>
inherited from Tone.AudioNode

.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();
</>
inherited from Tone.AudioNode

.connect ( )

#
outputNum

optionally which output to connect from

type: number
default: 0
inputNum

optionally which input to connect to

type: number
default: 0
↪ returns Tone.AudioNode

this

connect the output of a ToneNode to an AudioParam, AudioNode, or ToneNode

</>
inherited from Tone.AudioNode

.disconnect ( )

#
output

Either the output index to disconnect if the output is an array, or the node to disconnect from.

↪ returns Tone.AudioNode

this

disconnect the output
