MP3 / Audio QR Code
An MP3 / audio QR code is a dynamic code that links to an audio file hosted by Qravio. Scanning it opens a mobile landing page with a built-in player so anyone can instantly stream or download the track. Because it's dynamic, you can replace the audio file later without reprinting the code.
How a MP3 / Audio QR code works
You upload an MP3 (or other audio file) to Qravio, which hosts it and encodes a short link into the QR code. When someone scans it, their phone browser opens a branded landing page with an audio player to stream or download the file. Editing the dynamic code lets you point it at a new track later, and every scan is logged in analytics.
Popular uses

- Authors and publishers linking to audiobook samples or chapter previews on book covers
- Language teachers giving students instant pronunciation clips on printed worksheets
- Wedding and event organizers sharing playlists, voice messages, or recorded toasts

MP3 / Audio QR code FAQ
What audio formats can I use in an MP3 QR code?
MP3 is the most universally supported format and plays in every mobile browser. Qravio also accepts common formats like WAV and M4A, but MP3 is recommended for the smallest file size and broadest compatibility.
Can I change the audio file after printing the QR code?
Yes. The MP3 QR code is dynamic, so you can upload a new track in your Qravio dashboard at any time and the printed code will play the updated audio with no reprint needed.
Do people need an app to play the audio?
No. Scanning opens a standard mobile web page with a built-in audio player, so listeners can stream or download the file directly in their phone's browser without installing anything.
Can I track how many times my audio QR code is scanned?
Yes. Every scan is recorded in Qravio's real-time analytics, showing total plays plus scan time and approximate location, even on the free tier.
