Fascinating. Thank you.

Why do you need to know more about the file to transform to frequency domain?

Because no information is lost if you simply change domain, but you may spot more patterns faster or easier. For example (even if a bit dated) https://ieeexplore.ieee.org/abstract/document/1614066

There is a lot of research in this field because of the IoT fad/trend. If you want to know more i would suggest to simply pic a paper from IEEE and deep dive into the terms and terminology and simply skip the proofs of most algorithms/theorems.
