Electric Network Frequency Analysis question

[ric29]

Few days ago I've found this article about integrity of digital audio evidence:
http://equinoxjournals.com/ojs/index...ticle/view/525

This article reports on the Electronic Network Frequency Criterion as a means of assessing the integrity of digital audio evidence. A brief description is given of phenomena that determine ENF varaiations. In most situations,to reach a non-authenticity option, the visual inspection of spectrograms and comparison with an ENF database are enough.....

It has been so interesting, I've tried to make some googling about this subject.
And a nice surprise was here:

How have I missed it before???

My question is-as the tutorial is few years old and a bit too complicated for beginners, is any text how it can be done in few simple steps for not too advanced users of DCLive?

Thx

I wish that we could give you a few steps that would allow you to deal with this sort of tape authentication method, but it really is quite complex and far beyond my ability to post a paragraph and have the concept to be understood by the readers.

Suffice it to say that Diamond Cut Live is used both to log the power line data (note that it can record at sample rates as low as 100 samples per second for protracted data logging purposes) and to compare that data to that which is extracted from surveilance recordings. I think that this would make a good one day seminar adjunct to the existing 3 day Forensics seminar that we presently offer. Maybe it would be worth it to develop this topic a bit more.

All that I can say right now is that you do have the right software tools to do the job.

OK, I follow you
