Building an audio volume meter in Reactjs: A step-by-step guide

Looking for suggestions on creating a visually appealing volume meter bar using Reactjs and Material ui. I have a basic implementation with LinearProgress, but now I want to upgrade it with a new design. Any tips on how to achieve this using Material-ui? All suggestions are welcome!

Basic Code:

class AudioProgress extends Component {
  render() {
    const { classes } = this.props;
    return (
        <LinearProgress variant="determinate" value={10} className="audio-meter"/>
     );
  }
}

export default  withStyles(styles)(AudioProgress);

UPDATE: I've added some HTML to get started with the progress bar. Now, I need suggestions on how to update/change it for color updates. Any further ideas?

Starter Code:

render() {
    const value = 20;
    return (

          <div class="container">
            <div class="progress-segment">
              <div class="item "></div>
              <div class="item "></div>
              ...
              <div class="item"></div>
            </div>
          </div>
          
     );
  }

Answer №1

While I'm not an expert in react, I can give you a starting point in the right direction. If there's a more efficient "react way" to accomplish this, I welcome any suggestions.

Check out this link for a live example.

The concept is simple - you have several divs representing bars, initially colored gray. As you input a volume (e.g. 80 for 80% volume), each bar is looped through to determine if it should turn green based on the volume threshold calculated by dividing the volume by the total number of bars. For instance, in my case with 5 bars, the threshold is set at 20 (100 / 5). If the condition is met, a different class is added to color the bars green. Feel free to reach out if you have any questions.

Answer №2

If you're in search of a solution, one possibility is to explore the premium themes offered by Material UI. It's highly likely that some of these themes align with your requirements. You can view the available options here.
