4sync is an integrated software and hardware system that allows for real-time synchronization of any multichannel audio stream to a video stream in any VR headset model.

 

For Eyes takes care of setup, and in most cases headset procurement as well.

 

The 4sync application is installed on headsets and the transmission system is connected to either a digital or analog LTC output pertaining to the audio stream. The transmission system may be a desktop app for software-only applications such as use with a DAW, or involve a small proprietary hardware device compatible with the specific configuration of cinema halls / DCPs. 

 

The administrative app allows for real-time status monitoring and control of all headsets connected to the system by an operator at the event space.

​​

  • LTC monitoring + transmission system (desktop application or hardware device) including WiFi router(s)

​

  • 1 - 1000+ headsets (may also be provided by client)

​

  • Device for administrative app operation (may also be provided by client) iPhone, iPad, MacOSX, AppleTV, Android devices, Windows compatible devices
