ENF matching

The example code from my blog post about ENF matching: "How to date a recording using background electrical noise". This script predicts when a target recording was taken by comparing its background electrical noise to a reference recording.

Requirements

• Python3
• Virtualenv (or similar)
• Curl (for downloading sample files) (can also download manually)

Usage

Setup

virtualenv venv
source venv/bin/activate
pip3 install -r requirements.txt

Download sample files from https://github.com/ghuawhu/ENF-WHU-Dataset:

./bin/download-examnple-files

Run

source venv/bin/activate
python3 main.py

Should output:

True value is 71458
Best prediction is 71460
