Blackman–Tukey spectral estimation and electric network frequency matching from power mains and speech recordings

Blackman–Tukey spectral estimation and electric network frequency matching from power mains and speech recordings

Abstract Forensic applications exploit electric network frequency (ENF) as a fingerprint to determine multimedia content authenticity, as well as the time and region of multimedia recording. ENF is present at a nominal frequency of 50/60 Hz and its harmonics. Strong interference due to speech conten...
