Yesterday I had a nice conversation with one of you, my lovely readers 😊 Caroline asked me if I've ever written a post about QR codes, specifically about putting sound into them. My initial thought was "not really, because it's easy, right?". That lasted about a nanosecond because I remembered that actually it's not that straight forward and it took me some time to figure out how to do it. So, per Caroline's requests I'm going to tell you how I make QR codes with sound.
Step one: create an audio file
You can't create a QR code with sound without, well, the sound 😜 There are a couple of ways to get the recording: you might use an audio file from a course book you're using; you could use Vocaroo.com which is a free voice recording website; you can also use a dictaphone app on your phone.
If you use Vocaroo, you're pretty much done at this point. Vocaroo offers the option of downloading your recording as a QR code. You simply click on it and get a QR code which you then simply save on the computer with the right click "save picture as ..." option. You need to remember, however, that Vocaroo stores your recordings for a limited time and the generated QR codes will stop working at some point.
Step two: upload your audio file
If you want your recordings to keep working for as long as you want them to you need to do a bit more. After you make your recording you need to upload onto a cloud service online. I use Google Drive for that.
Log into your Google account (if you don't have one, create one first). Go to Google drive and click the upload option. Pick a file from your computer and upload it. Once your file is uploaded, right click on it and get the "shareable link". Copy that link and move on to the last step.
Step three: create the code
Once you have your shareable link go to any online QR code generator. I use this website. Chose the URL option in the menu and paste your link. Click save, name your file and click save again. Voila! You've got your audio QR code 😁
