Reusable synthesis components.

Audio Modules

SimpleGain

The SimpleGain is a linear amplitude processor that applies gain to input data.

Constructor

new SimpleGain(context, [options])

Create a SimpleGain instance. context must reference an AudioContext instance. options is an object containing configuration settings for the instance. Configurable options and their default values:

const defaults = {
  connect: context.destination,
  gain: 1,
};

SimpleOscillator

The SimpleOscillator is a variable wave shape oscillator capable of CV and audio rate frequencies.

Constructor

new SimpleOscillator(context, [options])

Create a SimpleOscillator instance. context must reference an AudioContext instance. options is an object containing configuration settings for the instance. Configurable options and their default values:

const defaults = {
  connect: context.destination,
  frequency: 440,
  detune: 0,
  type: 'sine',
};

Control Modules

SimpleEnvelope

The SimpleEnvelope is a linear response Attack-Release (AR) envelope.

Constructor

new SimpleEnvelope(context, [options])

Create a SimpleEnvelope instance. context must reference an AudioContext instance. options is an object containing configuration settings for the instance. Configurable options and their default values:

const defaults = {
  connect: undefined,
  attack: 0.1,
  release: 0.4,
};

Properties

• SimpleEnvelope.attack: InterfaceParam representing the time in seconds for the envelope to rise from a value of 0 to 1. Set with attack in the constructor options or with AudioParam.value.
• SimpleEnvelope.release: InterfaceParam representing the time in seconds for the envelope to fall from a value of 1 to 0. Set with release in the constructor options or with AudioParam.value.

Methods

• SimpleEnvelope.trigger(): Run the envelope's generated stages.
• SimpleEnvelope.getLength(): Return the sum of the AR stages.
