constructor(page: Page) {

    this._recorder.debug = true; // set true for tns_recorder logs

    this.currentVolume = 1;
    this._slider = page.getViewById('volumeSlider') as Slider;

    // Set player volume
    if (this._slider) {
      this._slider.on('valueChange', (data: any) => {
        this._player.volume = this._slider.value / 100;
