Methods

(static) convolve(buffer, options) → {AudioNode}

Create a convolver

Parameters:
Name Type Description
buffer AudioBuffer
options Object

(Optional) options may include:

  • normalize: true to normalize the buffer
  • context: the audio context to use
Source:
Returns:

the convolver (ConvolverNode)

Type
AudioNode
Example
reverb = mix(convolve(sample('emt-140.wav')))
connect(subtractive(880, { perc: [0.1, 1] }), reverb(0.2))

(static) decayIR(duration, options) → {AudioBuffer}

Create a reverb impulse response using a logarithmic decay white noise

Parameters:
Name Type Description
duration Number

the duration in samples
options Object

(Optional) options may include:

  • decay: the decay length in samples
  • attack: the attack time in samples
  • reverse: get the reversed impulse
  • context: the context to use
Source:
Returns:

the impulse response audio buffer

Type
AudioBuffer

(static) delay()

A mono or stereo delay with filtered feedback

Source:

(static) dly()

Create a delay (a DelayNode object)

Source:

(static) feedback(amount, node, options) → {AudioNode}

Create a feedback loop.

Parameters:
Name Type Description
amount Integer

the amount of signal
node AudioNode

the node to feedback
options Object

(Optional) options may include:

  • context: the audio context to use
Source:
Returns:

the original node (with a feedback loop)

Type
AudioNode

(static) mix(wet, fx, options) → {AudioNode}

Mix an effect with the signal. Can be partially applied to create an effect bus.

Parameters:
Name Type Description
wet Number

the amount of effect (0-1)
fx AudioNode

the effect unit
options Object

(Optional) may include:

  • compensate: it it's false, the dry signal gain will pass without reduction. If true (it's true by default) the dry signal is reduced the gain of the wet signal.
  • context: the audio context
Source:
Returns:
Type
AudioNode
Examples
mix(dB(-3), delay(ms(800)))
// create an effect bus
var rev = mix(reverb(2))
conn(sine(300), rev(0.2))

(static) reverb(duration)

Create a simple reverb

Parameters:
Name Type Description
duration Number

in seconds? WTF?
