Offline Sound Recognition Service

Optimized offline ACR can recognize advertisements, programs and films without an internet connection. It can be used in environments where a signal may be unavailable, such as cinemas, subways and airplanes.

Participation in promotions and coupon programs while offline is reported to the server when the user’s device reconnects, keeping information up to date and improving the service.

Offline audio recognition matches against a compact audio fingerprint database stored on the user’s smart device. Its indexing database design supports fast, stable recognition.
