Why an audio QR code
A recorded voice explains what a printed label cannot: how an exhibit was made, how a word is pronounced, what a street sounded like a century ago. An audio QR code opens a recording on the visitor's phone. Paste a link to an MP3 or another audio file on your website or cloud storage, or to an episode on a podcast platform, and the scan goes straight there. The recording itself is not uploaded to QR Global: the code keeps a short, editable link to it, so the narration can be replaced later without a new print run.
- Plays a recording from your own hosting or a podcast service, opened by any phone camera.
- Replace the file, for example with a corrected narration, without touching the printed code.
- Smart redirects on higher plans let one code open a different recording for each browser language.
- Scan counts reveal which exhibits or pages people really listen to.
Museum and gallery guides
A code beside each exhibit opens a short narration, so the museum needs no rented headsets.
City walks and heritage trails
Signs along the route play the story of each stop while visitors look at the building itself.
Language learning
Textbooks and flashcards link to the correct pronunciation of words and dialogues.
Greeting cards and gifts
A recorded message or a song starts once the card or the gift tag is scanned.
Real estate and products
A listing sign or a product tag plays a short spoken description for people who prefer listening to reading.

Audio QR Code Generator
An audio QR code turns any printed material into a listening experience. Scan it, and the sound plays right away through the browser's built-in player — no separate app required.
What is this QR code?
An audio QR code plays a recording you host, typically an MP3 or M4A file or a podcast episode, in the phone's browser or podcast app.
Best use cases
- ✓A museum audio guide explaining an exhibit to visitors.
- ✓A voice greeting on a card or gift package.
- ✓An audio instruction for visually impaired visitors at a public venue.
- ✓A musician's demo track on a concert poster.
How to generate your QR code
Upload the recording to your website, a cloud drive or a podcast host.
Paste the direct link to the MP3, M4A or episode page.
Play the link on a phone first to make sure it starts without a sign-in.
Print the code beside the exhibit, page or product the recording describes.
Frequently Asked Questions
Do I need an app installed to hear the audio?
No, in most cases the file plays directly through the browser's built-in player without needing a separate app.
Which audio format should I use?
MP3 is the most universally supported format across devices, offering the best balance of quality and file size.
What kind of link works best?
A direct link to the audio file, ending in .mp3 or .m4a, plays in the phone's browser player. A Google Drive, Dropbox or OneDrive link opens that service's preview page instead, and it must be shared with anyone who has the link.
Which format and size work best?
MP3 and M4A play on practically every phone. Visitors often listen over mobile data, so keep each file short: at 128 kbps a minute of speech takes about 1 MB, while the same minute as WAV is roughly ten times larger.
Can the guide speak the visitor's language?
Yes, provided smart redirects are part of your plan. Add a language rule for each translation: a phone set to German gets the German recording, and everyone else hears the default link.
Does QR Global host my audio files?
No. Upload the recording to your site, to cloud storage or to a podcast host and paste its address. The code stores only that link, which you can change at any time.
Does the recording start by itself?
It varies by phone and by the site hosting the file. Most browsers show a player and wait for a tap on Play, which is why a short caption next to the code, such as “tap to listen”, helps.
What if there is no mobile signal?
The recording streams from the internet, so it needs mobile data or Wi-Fi. In basements and thick-walled buildings, check the signal where the code will hang, or place a Wi-Fi QR code next to it.
