1.0.0

v0.20.0

0.20.0 (2018-03-28)

Features

• api: Use functions for creating virtual audio nodes (7ee89ed)

BREAKING: If using commonJS createVirtualAudioGraph must be imported as:

const createVirtualAudioGraph = require('virtual-audio-graph').default

BREAKING: Nodes in the audioGraph are now defined using functions instead of arrays

Inspired by https://github.com/ohanhi/hyperscript-helpers

Instead of:

import createVirtualAudioGraph from 'virtual-audio-graph'

const virtualAudioGraph = createVirtualAudioGraph()
const {currentTime} = virtualAudioGraph

const graph = {
  0: ['gain', 'output', {gain: 0.2}],
  1: ['oscillator', 0, {
    type: 'square',
    frequency: 440,
    startTime: currentTime + 1,
    stopTime: currentTime + 2
  }],
  2: ['oscillator', 0, {
    type: 'sawtooth',
    frequency: 660,
    detune: 4,
    startTime: currentTime + 1.5,
    stopTime: currentTime + 2.5
  }],
}

virtualAudioGraph.update(graph)

We now have:

import createVirtualAudioGraph, {gain, oscillator} from 'virtual-audio-graph'

const virtualAudioGraph = createVirtualAudioGraph()
const {currentTime} = virtualAudioGraph

const graph = {
  0: gain('output', {gain: 0.2}),
  1: oscillator(0, {
    type: 'square',
    frequency: 440,
    startTime: currentTime + 1,
    stopTime: currentTime + 2
  }),
  2: oscillator(0, {
    type: 'sawtooth',
    frequency: 660,
    detune: 4,
    startTime: currentTime + 1.5,
    stopTime: currentTime + 2.5
  }),
}

virtualAudioGraph.update(graph)

BREAKING: Custom nodes must now be created with the createNode function:

import {createNode, delay, gain, oscillator, stereoPanner} from 'virtual-audio-graph'

const pingPongDelay = createNode(({
  decay = 1 / 3,
  delayTime = 1 / 3,
  maxDelayTime = 1 / 3,
} = {}) => ({
  0: stereoPanner('output', {pan: -1}),
  1: stereoPanner('output', {pan: 1}),
  2: delay([1, 'five'], {delayTime, maxDelayTime}),
  3: gain(2, {gain: decay}),
import {createNode, delay, gain, oscillator, stereoPanner} from 'virtual-audio-graph'

const pingPongDelay = createNode(({
  decay = 1 / 3,
  delayTime = 1 / 3,
  maxDelayTime = 1 / 3,
} = {}) => ({
  0: stereoPanner('output', {pan: -1}),
  1: stereoPanner('output', {pan: 1}),
  2: delay([1, 'five'], {delayTime, maxDelayTime}),
  3: gain(2, {gain: decay}),
  4: delay([0, 3], {delayTime, maxDelayTime}),
  five: gain(4, {gain: decay}, 'input') // note this is the destination for nodes which connect to pingPongDelay
}))

virtualAudioGraph.update({
  0: pingPongDelay(
    'output',
    {decay: 1 / 4, delayTime: 1 / 3, maxDelayTime: 1},
  ),
  1: gain([0, 'output'], {gain: 1 / 4}),
  2: oscillator(1, {frequency: 440, type: 'square'}),
})
