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, 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.

And what is a common item to circuit boards, IC's, cell phones, pagers, MP3
players, etc.

Yes, which is one of the reasons why detection of these
won't help, unless ALL such devices are banned which is
unlikely... but again, we dont have the specific scenario to
consider.


There are devices made to detect the presence of semiconductors, and these
have been out for ages.
And now with the war on terror going on, you would not believe what kind of
sensors they are coming up with.

I would believe you are taking a random unfounded
presumption that someone "could" be possible without
supporting evidence, nor consideration of what would be
necessary to distinguish this particular device.

Minor modifications of some of these units would not be very difficult to
detect a mere MP3 in someones pocket.

Unfounded speculation. "Maybe" it's easy enough to detect
the device when turned off. "Probably" if you were close
enough to the device you could even detect that it's turned
on. That's a far cry from identification as an MP3 player,
let alone one that is recording, vs another mode of
operation (like playback, wouldn't it be highly possible
someone who has an MP3 player, would have it to play MP3?)

But then these would not be cheap either, if you can even get one.

Establish that such a device exists at all, that can detect
an MP3 player recording, specifically discriminate it from
other devices. Nevermind if we can buy it or how much it
costs, establish that it can be done at all as so far you
have not.
