- The claim rests on the recording's electric network frequency trace — the tiny fluctuations of the mains hum, which drift in a way that can be matched against grid records to time-stamp a recording.
This sourceShows that a recording's ENF trace can be matched against reference-frequency records to test or identify its recording time.
