# ENF matching
The example code from my blog post about ENF matching: ["How to date a recording using background electrical noise"](https://robertheaton.com/enf). 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
```
