Lay ENF analysis has been POC'd by Robert Heaton #16

Closed m31r2701 closed 6 months ago

Details of the proof-of-concept here: https://robertheaton.com/enf/

His example code on GitHub: https://github.com/robert/enf-matching

He explains that his code can be extended to:

include Hua et al.'s algorithm to determine the presence of mains hum in a recording, and;
to take harmonics into consideration.

This isn't really an open question any more - ENF matching is now a trivial problem that anyone with intermediate Python skills can solve by slightly modifying Heaton's code.

I disagree that it's trivial; sure, you can exact the ENF signal from a recording, but doing so reliably and matching that signal with real ENF databases remains out of reach for most. I think there is still an opportunity here for someone to make a great tool.

@milesmcc tbf, given that no-one seems to have forked the code to release a public tool yet, I was probably being a bit cavalier describing it as a "trivial" problem

All good! I just want to make sure no one sees this and thinks that the work is done.
