Constructor

BB.AudioBase ()

Defined in src/BB.AudioBase.js:11

Example:

in the example below instantiating the BB.AudioBase creates a GainNode ( essentially the modules's output ) connected to the default BB.Audio.context ( ie. AudioDestination )


 BB.Audio.init();

 var node = new BB.AudioBase();

 // or optional config property
 var node = new BB.AudioBase({
    context: BB.Audio.context[2],
    connect: fft,
    volume: 0.5
});

Properties

ctx AudioContext default:BB.Audio.context

Defined in src/BB.AudioBase.js:39

the Audio Context this derived from

gain GainNode private

Defined in src/BB.AudioBase.js:57

the "output" gain node ( use .volume, .setGain() to interface with this )

volume Number default:1

Defined in src/BB.AudioBase.js:89

the master volume (of output gain node)

Methods

connect
(
  • destination
  • output
  • input
)

Defined in src/BB.AudioBase.js:109

connects the Noise to a particular AudioNode or AudioDestinationNode

Parameters:

  • destination AudioNode

    the AudioNode or AudioDestinationNode to connect to

  • output Number

    which output of the the Noise do you want to connect to the destination

  • input Number

    which input of the destination you want to connect the Noise to

Example:


 BB.Audio.init();

 var node = new BB.AudioBase({
    volume: 0.75,
 });

  node.connect( exampleNode );
  // connected to both default BB.Audio.context && exampleNode
  // so if exampleNode is also connected to BB.Audio.context by default,
  // ...then you've got node connected to BB.Audio.context twice
...which looks like this ( where the first Gain is the Noise and the second is the exampleNode )

disconnect
(
  • destination
  • output
  • input
)

Defined in src/BB.AudioBase.js:153

diconnects the Noise from the node it's connected to

Parameters:

  • destination AudioNode

    what it's connected to

  • output Number

    the particular output number

  • input Number

    the particular input number
     BB.Audio.init();

     var node = new BB.AudioBase({
        volume: 0.75,
     });

     node.disconnect(); // disconnected from default BB.Audio.context
     node.connect( exampleNode ); // connected to exampleNode only
    ...which looks like this ( where the first Gain is the node and the second is the exampleNode )

setGain
(
  • num
  • ramp
)

Defined in src/BB.AudioBase.js:197

sets the gain level of the node ( in a sense, master volume control )

Parameters:

  • num Number

    a float value, 1 being the default volume, below 1 decreses the volume, above one pushes the gain

  • ramp Number

    value in seconds for how quickly/slowly to ramp to the new value (num) specified

Example:


 BB.Audio.init();

 var node = new BB.AudioBase({
    volume: 0.75
 });

  node.setGain( 0.25, 2 ); // lower's volume from 0.75 to 0.25 in 2 seconds
// if no ramp value is needed, you could alternatively do
  node.volume = 0.5; // immediately jumps from 0.25 to 0.5
