Is there anyone experienced with implementing an ambient music file in a loop and playing automatically in the background of the home page on a Webflow website?

TL;DR
  • Upload a small .mp3/.ogg audio file, embed a hidden <audio> tag with autoplay, loop, and muted attributes.
  • Add JavaScript triggered by a user click to unmute and play the audio due to browser autoplay restrictions.

To add ambient background music that autoplays and loops on a Webflow homepage, you must work within browser autoplay policies and Webflow’s capabilities.

1. Prepare the Audio File

  • Ensure the file is in .mp3 or .ogg format for broad compatibility.
  • Keep it small (under 1MB) so it loads quickly.
  • Host the file on Webflow (Assets panel) or an external source like Dropbox, AWS S3, or Google Cloud.

2. Add Embed Code in the Page (Custom Code)

Since Webflow doesn't have a native audio player element with autoplay and loop, you’ll use a custom embed block.

  • Drag a “Embed” component anywhere onto your homepage (typically placed at the top or inside a hidden section).
  • Paste this inline audio tag:
    <audio autoplay loop playsinline muted id="bg-music"> <source src="YOUR_AUDIO_URL_HERE" type="audio/mpeg"> </audio>
    Replace YOUR_AUDIO_URL_HERE with your uploaded audio file’s URL.

3. Handle Autoplay Limitations

Most browsers block autoplay with sound. Here are workarounds:

  • The muted attribute allows autoplay but no audio will play until unmuted. You’ll need JavaScript to unmute after user interaction.

  • Add a Start button or “Tap to enter site” that, when clicked, unmutes the audio:

  • Add a button with an ID e.g., start-audio.

  • Add this in the Before section under Page Settings → Custom Code:

    document.getElementById("start-audio").addEventListener("click", function() { var audio = document.getElementById("bg-music"); audio.muted = false; audio.play(); });

4. Make the Audio Player Invisible

To keep the player running silently in the background:

  • Add style="display:none;" to the tag, or wrap it in a hidden div.
  • This ensures no visible audio controls.

5. Publish and Test

  • Publish the site to your Webflow staging domain.
  • Test on multiple browsers (Chrome, Safari, Edge) to make sure autoplay works after user interaction.

Summary

To add ambient background music on Webflow, upload the file, embed a hidden <audio> tag with autoplay and loop, and unmute it using JavaScript after a required user interaction. Browsers block autoplay with audio unless muted or triggered by the user.
