Check out the Boombotix Sync app. Technology is very similar.

get the protest kids doing this and you'll get some great press

Cool app!

Fun idea. Think it has more benefit for conferences and meetings, but nice idea

Work to get reduce latency -- sync is tough. Very cool work on getting the sync figure out. Thanks for using Dolby. Please talk to developer.dolby.com when you're ready to submit this app to Amazon.

Neat tech! Would like to see this in production -- see also http://soundtrack.io

Cool concept... Not sure 100 shitty sounding speakers in unison will make things sound better than the original; but I would focus on different spaces like walking tours or something similar.

Audio collaboration to sync music playing. Many other apps do this.

great idea
