Frequently Asked Questions

Say what now?

If you’ve never heard of The Mp3 Experiment, check out our coverage of the past ten years. In addition to The Mp3 Experiment, Improv Everywhere organizes hilarious participatory public projects year round. Check out the rest of this site to see our work!

How will we know when to start?

You will have synchronized your watch or cell phone clock to the atomic clock above. If your phone does not allow you to adjust by seconds, you have two choices: 1) Bring a watch. 2) Figure out how off your phone is and adjust accordingly.

Can I use my iPhone/Android phone?

Yes, but if you use a phone, be sure to put it in airplane mode so you don’t get interrupted by a call. Also, as noted above your automatically set clock could still be several seconds off. So note the difference and adjust accordingly, or download this app (iOS) that will show you the correct time.

Should I listen to the track beforehand?


Can I listen to the track beforehand?

You really shouldn’t. Sure, there’s nothing we can do to stop you, but to really get the full experience of the event, you shouldn’t listen to it. It will spoil most of the fun. We know it’s hard to resist. Be strong.

What if I get to the event late?

Press play at the start time wherever you may be, and hurry up! Obviously be safe and don’t rush when crossing streets, etc.

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

If you can tell you are significantly off, feel free to glance 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.
