2. Audacity: Recommendations
Recommendations Recap:1. Select the correct microphone and stereo channel
2. DO NOT press “stop” or “record” until prompt says “you may stop your recorder” – only “pause”
3. Make sure there is only 1 track recorded (no overlapping tracks)
4. Export entire response (not individual) to .MP3 no .WAV
5. Save file as AP number for easier processing
6. Save file to Folder “AP [subject] Exam, [form code]”
7. Save Audacity project if possible (as backup)
3. Common Problems
I got 99 problems… and an AP test ain’t one!
1. For students
2. For proctors
3. For IT team
3. Common Problems: Students
Microphone:• Not calibrated properly – may have to adjust in system preferences• Accidentally muted – some headsets have mute button• Check the right input source is selected in Audacity
Recording:• Do not hit “record” once the recording has started – only press
“pause”• Do not hit “stop” until end of exam
Saving Recordings:• Export student recordings as .MP3 and not any other format• Save file name as 8 digit AP number and not student’s name• Do not log out / restart / shut down computer after exam
3. Common Problems: ProctorAudio Playback:• CD skipping – have backup playback device• Audio volume – ensure all students can hear audio over their
headsets
File Collection:• Have some way to collect student recordings • Have backup option just in case (ie. Flashdrive)
Preparing Recordings for Submission• File is saved as .MP3 file• Filename is 8 digit AP number – no student identifying information• Burn file as data CD and not as an audio CD• Assign CD with 8 digit AP number label
3. Common Problems: IT TeamComputer Setup Prior to Exam• Make sure all computers have power (if using laptop)• Ensure:
• Headsets work• Students can log into machines • Audacity is installed• LAME compression library for .MP3 processing is installed in
Audacity• Power saving features are turned off (screensaver, auto-lock, etc.)• Students can create folders on desktop• Recordings saved on desktop are not deleted when students log
out or turn off computers• Provide blank CD-R’s for submission to CollegeBoard
DiLL: The Digital Language Lab
• All software (no proprietary hardware)• Built specifically for Macintosh
computer• Developed at Northwestern University• Over 10,000 AP exams successfully
administered
4. DiLL• Designed to streamline process and reduce
human and technical errors• All controls handled by proctor:
• Proctor streams out exam audio from their computer to students’ headsets synchronously
• Proctor controls “record” button for all students simultaneously
• Recordings automatically collected and processed as .MP3 with student’s 8 digit AP number
• DiLL YouTube walkthrough (~5 mins) bit.ly/APDiLL
