Looping about react-sound HOT 8 CLOSED

Hi @mukesh-urbanpiper! The problem with the code you pasted is that you're trying to think about it in an imperative style. You cannot do Sound.position since that's not doing what you intend it to do. The only way to change the props of a component is in the render method, by passing new props when the component re-renders.

To play in loop you need to keep the position controlled with local state, and when the song finishes playing, reset it to 0 so that it starts again. To update the position though, you need to use the onPlaying prop. This is an example that does what you want:

class Notification extends React.Component {
  constructor(props) {
    super(props);
    this.state = { position: 0 };
    this.handlePlaying = this.handlePlaying.bind(this);
    this.handleFinishedPlaying = this.handleFinishedPlaying.bind(this);
  }

  handlePlaying(ev) {
    this.setState({ position: ev.position });
  }

  handleFinishedPlaying() {
    this.setState({ position: 0 });
  }

  render() {
    return(
      <Sound url="./audio/a2.mp3" 
        playStatus={Sound.status.PLAYING}
        position={this.state.position}
        onPlaying={this.handlePlaying}
        onFinishedPlaying={this.handleFinishedPlaying}
      />
    );
  }
};

Take a look at how the example handles the position of the sound using local state and re-rendering the component every time the position updates.

Hope this helps!

It should be fairly easy, you can pass a callback prop to onFinishedPlaying and reset the position prop back to 0 anytime that one gets called.

@leoasis The problem is that I don't want user to sense audio's ending.

The best solution I can think of is to start playing the same audio in a different Sound element before the first one ends. But this one seems too complicated, so if there isn't a better way, I'll try resetting position something close to 0 just before the audio ends using onPlaying.

Ah so maybe I didn't understand the use case. The idea is to restart the sound when the sound wave is small enough that the user doesn't perceive anything anymore?

from react-sound.

The exact use case is, I am working on an application that plays calm sound tracks that will help user to focus. User selects the tracks to be played, and those tracks are played simultaneously. And I need to make a loop of the track, without user noticing track's ending or restarting.

Have you tried using the loops property of soundmanager2 (the underlying lib that actually plays the sound)? I believe this will cause the same effect as in the approach I suggested, but if for some reason it makes the restart smoother, it may be worth adding it to the lib somehow. If not, and you still need to restart a bit before the sound finishes, since it's a too specific use case, I'm afraid you'll have to resort to solving it in user-land

Hope the above answer was good enough for your use case! Closing this issue since it's a little old, but feel free to reopen if you still need help

Hi @leoasis , I am trying to play the audio in loop. But it seems I'm missing something.
Here is my component.

const Notification = React.createClass({
	repeat:function(){
		Sound.position = 0;
	},
	render: function(){		
		return(
			<Sound	url="./audio/a2.mp3" 
playStatus='PLAYING' 
position={0} 
onFinishedPlaying={this.repeat}/>
		)
	}
})
