What is Songle Sync?

"Songle Sync" is a novel technology that can drive hundreds of smartphones and personal computers to show graphic-based animations synchronized with music playback.

Songle Sync is a large-scale music-synchronized control platform, which is publicly available as an outcome of research and development by the National Institute of Advanced Industrial Science and Technology (AIST), Japan. This time we are presenting a special version of Songle Sync used to control a TextAlive animation, but you can always experience the power of Songle Sync on its official website for free! Access the web site with your own smartphone or personal computer and invite neighbors to enjoy graphic-based animations synchronized with your favorite music. The animations are dynamically generated on your device so that the amount of transferred data remains compact.

Organized by Crypton Future Media, INC.

In collaboration with RecMus Project, National Institute of Advanced Industrial Science and Technology (AIST)

Songle Sync by AIST is open to the public for academic purposes. Songle Sync collaborates with "Hatsune Miku Birthday Message Project 2021 : A Collaboration with Songle Sync" as part of their experimental research demonstrations.
