Here are the full details for The Mp3 Experiment happening at Truman State University. Please take the time to read all of the instructions on this page.


Date: Monday, September 13
Location: The Quad
Time: The event will begin at exactly 04:30:00 PM. Arrive early! It will be over by 5:15.
Wear: A mask and a red, yellow, blue, or green shirt


Download the audio file using our app:

Mp3 Experiment iPhone App / Mp3 Experiment Android App

In the app, select the Truman State 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.

If you are having trouble with the iOS or Android app, you can stream or download the file instead via Soundcloud. In this situation, you would need to press play manually at 4:30 exactly.


This event is taking place on the Quad. Blend in with the area naturally as if nothing is up.

NOTE: this experience will ask for active participation at various points throughout the event. Students should only participate in activities they feel comfortable with.

When 04:30:00 Approaches:

Make sure you have the app open and the track will play automatically at 04:30:00. 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 on “do not disturb,” turn off the screen, and put your phone away and have fun!
