Sure, I am in the room and occasionally walk<br>down the aisles, but these enterprising students are still<br>often able to hide a smart phone from me.<br><br>The way these smart phone cheaters are usually caught<br>is when answering an essay question, they usually<br>look up the topic on Wikipedia and copy word for word<br>several sentences.<br><br>On these exams, there are a few audio identifications,<br>and recently one student did a surprising thing.<br>The audio example was from Pierrot Lunaire, and not only did<br>answer the question by writing down the title and composer
but<br>she ALSO WROTE DOWN the title and composer of a track by Webern<br>which was on the original CD that I ripped the Schoenberg<br>from.<br><br>To summarize, from an mp3/ogg file that was put on-line<br>of one track from a CD, the student was able to identify<br>_other_ tracks from the CD that were not put on-line.<br><br>How did the student do this? Here are links to the two sound<br>files that the students had access to:<br><br>https://www.dropbox.com/s/66qkorouak19gpu/07_20th-pilu_p03_15-18.mp3<br>https://www.dropbox.com/s/z17qoxey9ju4lei/07_20th-pilu_p03_15-18.ogg<br><br>Are there some tags embedded in these files? How would I<br>be able to see these tags myself?<br><br>If there are no embedded tags, how did this student obtain<br>this information?<br><br>Thanks; Ivan<br></div></div></body></html>
