Abstract
Various systems and methods may benefit from determination of environmental signatures in recordings. For example, such signatures may aid forensic analysis and alignment of media recordings, such as alignment of audio or video recordings. A method can include reading data representative of sensed light in a visual track of a video recording. The method can also include extracting an electric network frequency signal from the data representative of sensed light.
