The Cinewav app allows the downloading of an audio file for specific movie (or other audio-visual content) events held by Cinewav so you can watch the movie visuals on a big public screen while listening to the audio on your personal smartphone. The audio visual sync will happen in the app! The app has an audio file that will ONLY play when the Cinewav broadcaster application (for laptop) plays a particular file. When the laptop broadcaster application is set to play then the audio file on the Cinewav app will automatically play too. The user can then pause or play the audio file as they wish. If the laptop Cinewav broadcaster application is not playing anything then the play button will remain unresponsive (waiting for the play signal). It is for events held only by Cinewav, using the Cinewav broadcaster application on a laptop (for event holder) with users using the Cinewav app on their mobile phones.
