    <div>

      <button onClick={controls.mute}>Mute</button>
      <button onClick={controls.unmute}>Un-mute</button>
      <br/>
      <button onClick={() => controls.volume(.1)}>Volume: 10%</button>
      <button onClick={() => controls.volume(.5)}>Volume: 50%</button>
      <button onClick={() => controls.volume(1)}>Volume: 100%</button>
      <br/>
      <button onClick={() => controls.seek(state.time - 5)}>-5 sec</button>
      <button onClick={() => controls.seek(state.time + 5)}>+5 sec</button>
    </div>
  );
};

Reference

const [audio, state, controls, ref] = useAudio(props);
const [audio, state, controls] = useAudio(<audio {...props}/>);

audio is React's <audio> element that you have to insert somewhere in your render tree, for example:

<div>{audio}</div>

state tracks the state of the audio and has the following shape:

{
  "buffered": [
    {
      "start": 0,
      "end": 425.952625
    }
  ],
  "time": 5.244996,
  "duration": 425.952625,
  "paused": false,
  "muted": false,
  "volume": 1,
  "playing": true
}

playing: The audio is being played and is affected by the network. If it starts to buffer audio, it will be false

controls is a list collection of methods that allow you to control the playback of the audio, it has the following interface:

interface AudioControls {
  play: () => Promise<void> | void;
  pause: () => void;
  mute: () => void;
  unmute: () => void;
  volume: (volume: number) => void;
  seek: (time: number) => void;
}

ref is a React reference to HTML <audio> element, you can access the element by ref.current, note that it may be null.

And finally, props — all props that <audio> accepts.
