So it can tell semiconductor junctions of an MP3 recorder from
semiconductor
junctions of non-recording devices?

Th OP question was detection not *any* semiconductor device, but a MP3
recorder. By the way, the recorder doesn't have to be in that room.
Enough
to have a connected cellphone in a pocket.

Yep, and that can be detected.

By that you must specifically mean the cell phone.

No, by that I mean any electronic device, which may or may not be used to
record conversations.



What you do with the knowledge that the person has an electronic device
that
may or may not record is up to you and what you want to do.

It's essentially useless information

Nope, it will tell you that the person has an electronic device that may or
may not be used to record your conversation or take pictures.
This is where security comes in, and how much security you want to enforce.
