Tone.Gain

↳ EXTENDS Tone.AudioNode

A thin wrapper around the Native Web Audio GainNode. The GainNode is a basic building block of the Web Audio API and is useful for routing audio and adjusting gains.

CONSTRUCTOR

new Tone.Gain ( [
gain
] , [
units
] )
gain

The initial gain of the GainNode

type: Number
optional
units

The units of the gain parameter.

type: Tone.Type
optional

DEFAULTS

{
gain : 1 ,
convert : true
}

Members

.gain

Gain #

The gain parameter of the gain node.

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

.dispose ( )

#
↪ returns Tone.Gain

this

Clean up.

.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

.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

.fan ( )

#
nodes
↪ returns Tone.AudioNode

this

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

</>
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();
