JavaScript linx/mixins/readiness Examples

Example #1

File: buffer-source-node.js Project: linxmix/linx

import Ember from 'ember';

import ReadinessMixin from 'linx/mixins/readiness';
import WebAudioNodeMixin from 'linx/mixins/web-audio/node';
import { isValidNumber } from 'linx/lib/utils';

export default Ember.ObjectProxy.extend(
  WebAudioNodeMixin,
  ReadinessMixin('isAudioLoaded'), {

  // params
  audioBuffer: null, // WebAudioApi.AudioBuffer

  // implement web-audio/node
  node: null,
  outputNode: null,

  // implmement readiness
  isAudioLoaded: Ember.computed.bool('audioBuffer'),

  start(when, offset, duration) {
    // Ember.Logger.log('currentTime', this.get('audioContext.currentTime'));
    // Ember.Logger.log('startSource', when, offset);
    const args = [when, offset, duration].filter(isValidNumber);

    // web audio buffer sources can only be played once
    // therefore we must recreate source on each playback
    this.stop();
    const node = this.createBufferSource();
    node.start(...args);
  },
