Cell phone jamming is illegal for the most part, I believe.
I suggest you redesign your testing and set different (i.e., positive educational) goals for it.
In my experience good teachers usually know pretty well how students individually and collectively are doing, as long as the classroom is participative, not just a lecture.
You might use testing to see how the students are using what they have learned to solve problems as they would in the real world.
Welcome smartphones to the process and give lots of credit for contributing to the process. (You can use your own smartphone for that.)
Then you can publish articles about it and become a dean or vice president and spend the rest of your career fund-raising. (No good deed unpunished was probably invented in academia.)
Just kidding (mostly).

Hello LAD/LAU members:

I teach introduction to western music courses at a local
community college, and one thing I have to deal with is
students cheating by using a smart phone during the
exam.  Sure, I am in the room and occasionally walk
down the aisles, but these enterprising students are still
often able to hide a smart phone from me.

The way these smart phone cheaters are usually caught
is when answering an essay question, they usually
look up the topic on Wikipedia and copy word for word
several sentences.

On these exams, there are a few audio identifications,
and recently one student did a surprising thing.
The audio example was from Pierrot Lunaire, and not only did
answer the question by writing down the title and composer but
she ALSO WROTE DOWN the title and composer of a track by Webern
which was on the original CD that I ripped the Schoenberg
from.

To summarize, from an mp3/ogg file that was put on-line
of one track from a CD, the student was able to identify
_other_ tracks from the CD that were not put on-line.

How did the student do this?  Here are links to the two sound
files that the students had access to:

https://www.dropbox.com/s/66qkorouak19gpu/07_20th-pilu_p03_15-18.mp3
https://www.dropbox.com/s/z17qoxey9ju4lei/07_20th-pilu_p03_15-18.ogg

Are there some tags embedded in these files?  How would I
be able to see these tags myself?

If there are no embedded tags, how did this student obtain
this information?

Thanks;  Ivan

Another possibility:
There is also the possibility that the student was not cheating.
True, given the information you provided it seems unlikely, and you may
have additional indicators, but I'd simply ask her why she wrote down
that other track.

In my humble opinion, you won't ged rid of smartphone cheats unless you
use a different mode of examination. It just shows that factoid
checking is an anachronism.

Or you could do your exams in a Faraday cage in the basement of the building.

Or you could put in a cell phone jammer:

Or you could think out some way to resolve the problem that education seeks to evaluate an individual on individual achievement while in the business world you'll be expected to ask others for information and answers, and work together to succeed as a team.
