Usage

import { AUDIO_STATE, AudioState, AudioX, MediaTrack } from "audio_x";


// create an audio_x Instance
const audio = new AudioX();


// Initialize audio_x
audio.init({
  autoPlay: false,  // should auto play
  useDefaultEventListeners: true, // use Default event listeners
  showNotificationActions: true, // show notifications on devices
  preloadStrategy: "auto",   // preloading strategy
  playbackRate: 1,  // set playback rate
  enablePlayLog: true,  // enable playlog support
  enableHls: true,    // enable hls support
  hlsConfig: { backBufferLength: 2000 } // Hls init config
});

// create track
const track:MediaTrack ={
  artwork: [
    {
      src: "https://example.com/image.png",
      name: "image-name",
      sizes: "512x512",

  album: "Awesome Album",
  artist: "Amazing Artist",
  comment: "",

};

// add a track
audio.addMedia(track);

// play
audio.play();

//pause
audio.pause();

// Get the Audio State
audio.subscribe("AUDIO_X_STATE", (data: AudioState) => {
  console.log(data);
});

Getting the audio Instance

---

audio_x exports audioInstance, through a static method, so that you can add your own event-listeners directly on the HTML5 audio element.

const instance = AudioX.getAudioInstance();

Setting up the equalizer

---

// Getting the Presets
const presets = audio.getPresets(); // will return array of pre-tuned filters

// Sample Preset
[
  {
    "id": "preset_default",
    "name": "Default",
    "gains": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
  }
]

// Setting a Preset
audio.setPreset(id);

// example:
audio.setPreset('preset_default');  // will set default preset


// Custom EQ Setting

const gainsValue = preset[index].gains;
gainsValue[index] = value;  // value ranges from -10 to 10
audio.setCustomEQ(gainsValue);

// Example
const gainsValue = preset[0].gains;   // default preset gains [0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
gainsValue[0] = 2.5;   // updated gain values [2.5, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
audio.setCustomEQ(gainsValue);
