Download the audio file using our app:

Mp3 Experiment iPhone App / Mp3 Experiment Android App

In the app, select the UVU event, and click “Download” to join the event and download the file. After the file downloads, you will see a countdown timer. The app, if open, will play the track automatically at the right time when the timer reaches zero.

Please note: You should download the file in advance over a fast Wi-Fi connection. Do not wait until you are at the event to attempt to download.


As 9:40 AM approaches, blend in with the area naturally as if nothing is up, and stand or sit anywhere in the lawn area in front of Fulton Library.

When 09:40:00 Approaches

Make sure you have the app open and the track will play automatically at 09:40:00. Don’t forget to download the track in advance over Wi-Fi.

Do not use other apps on your phone during the experiment as they could interrupt playback. When it starts, turn off the screen and put your phone away and have fun!

Frequently Asked Questions

Say what now?

If you’ve never heard of The Mp3 Experiment, read about it here.

What if I get to the event late?

Start listening at the start time, and you’ll get there when you get there. Be careful crossing streets, etc.

What if I don’t press play at exactly the right time?

If you can tell you are significantly off, ask to look at a neighbor’s device and try to sync back up to the correct time. You’ll have more fun if you’re more in sync. Those using the app should automatically be in sync with atomic time.
