You man there actually is something which will detect MP3 recorders?

There are devices that can detect when electronic devices are being used.
There are devices that can be made that can detect almost any known
material
If said mp3 player is made of that material it can be detected.



Which is not entirely applicable,

Sure it is

since plenty of
non-recorders are made of circuit boards, ICs & other
discretes, and some plastic. Cell phone and pager are two
quite common ones.

Yep, and all are detectable, and all have signatures.

Detecting electronics devices in general, is it useful?

Depends on who you ask
The OP is not the only one who wants to ensure no one is able to record
conversations, or hear conversations they should not be hearing.

We
dont know the exact scenario,

He gave the scenario.

what the result would be of a
positive detection but as above, cell phones and pagers
would tend to be caught and are going to be far more common
and innocuous than a recording device, though in the former
case, the phone may have recording capability too.

True enough, but the technology is there to do what is being requested. Now
if the OP can afford it, or even obtain it is a different issue.
