ENFormant

ENFormant is a Python-based tool designed for Electrical Network Frequency (ENF) analysis, facilitating the forensic verification of audio and video recordings through the analysis of power grid frequency variations. Its notable features include advanced signal processing techniques such as multi-tone analysis and robust algorithms for comparing harmonic components, as well as enhancements for analyzing the rolling shutter effects in video data. The tool is applicable in forensic investigations and OSINT, providing a reliable method for timestamping and geolocating recorded content based on grid frequency patterns.
