Audio Comparison Lite


Click here for a live demo

This plugin is used to present audio files, typically two versions of the same audio (for instance, an unmixed, raw version and the final mixed version of a song), in a time synchronized manner: by switching seamlessly between files when the user presses the respective button.

Finally a direct A/B comparison is possible on your website! You can showcase as many files on one page as you like, completely independent from each other.

Pro Version

If you want

  • to avoid playing two sounds at the same time, and
  • to get rid of the play button and/or the accompanying text output,
  • and automatic styling of your buttons without manual CSS work including themes,

consider buying the full version. For the price of two beers you get all of the above and more!

You can also try it out here.


  • One way to present your files with Audio Comparison Lite.
  • Another way to set your A/B page up.
  • Audio Comparison Lite's settings.
  • Available shortcode parameters.
  • Available CSS classes.
  • Style editor with theme 'Audio Comparison'.
  • Style editor with theme 'studio kaedinger'.
  • Style editor with pro theme 'Sunny Sky'.


If not installing directly from the WordPress Plugin Directory:

  1. Download and unzip to your wp-content/plugins directory
  2. Alternatively, just upload the zip file via the WordPress plugins UI

After uploading, do the following:

  1. Activate the plugin via WordPress Admin
  2. Check and change Audio Comparison Lite’s setting page
  3. Include the shortcode [audiocomparisonlite] on your page or post (if using Blocks, use the Shortcode or HTML block).

The minimal shortcode looks like this:

[audiocomparisonlite file_a="PATH/TO/A.MP3" file_b="PATH/TO/B.MP3"]

Replace PATH/TO/A.MP3 and PATH/TO/B.MP3 with your own files. We recommend WAV or MP3.

Central settings, more shortcode options, and CSS guidelines can be found in the settings.

If there are multiple instances of Audio Comparison Lite on the same page, they all act independently. If you want automatic interaction (i.e. stop if another instance starts playing) and more styling options (get rid of the Play/Stop button for instance), then the full version at is for you.


For the time being, please refer to our demo/documentation page.

I've been looking for so long for a plugin that could do audio A/B comparison, in a seemless way... and finally it's here.It really works extremely well and you can mess up with the styling in so many parameters.It's a must have for any sound engineer who wants to share the "before and after" of his work with clients, in a very professional way.The customer help service is absolutely quick, efficient and very friendly.For all that, I must say that I recommend it 100%.

you know as an audio studio you want to show what you can do easily. this plugin does exactly that. it plays audio files time synchronized side-by-side. maybe a rewind button would be cool (hey designer!), but i actually like that it has no time bar. definitely buying the full version, just to support the designer
