What is an MP3?

MP3: MP3 is an acronym for MPEG-1 or MPEG-2 audio layer 3. MP3 is the file extension for MPEGaudio layer 3. Layer 3 is one of three coding schemes (layer 1, layer 2 and layer 3) for the compression of audio signals. Layer 3 uses perceptual audio coding and psychoacoustic compression to remove all superfluous information (more specifically, the redundant and irrelevant parts of a sound signal. The stuff the human ear doesn't hear anyway)

MP3

This following information is only a guide to on how to operate an MP3 player – each machine will have its own specific features. Before completing actual recordings for your students it may be advisable to spend some time ‘Getting to know the device’ and to make sure you are confident that when you sit with your student that the device will record and save your recordings.

what mp3 should you buy
What MP3 should you buy?
  • There are many different make and models of MP3’s and a wide price range. This may influence your choice, but as a minimum specification you should look for a device:
  • With the ability to record
  • With a USB connection (you may need to buy the USB as an extra)
  • With the facility to attach an external mic
  • With the facility to attached headphones

Reference to this site does not imply that CCEA supports the information contained on it and only serves as a guide to assist you in making an informed decision on the type of MP3 you require.

  • For more information you can visit the following site.
  • This is a question and answer from a user’s forum:
  • I have 500 hours of mp3 files on 8 cds that i want to load onto an mp3 player but I can't figure out what size player I need. I know 1 gig is 16 hours of audio files, but mp3 files are condensed. Right? Someone help please!!!
  • Answer:
  • The audio files are already compressed as you said they are in mp3 format. You say they are on 8 cds. They must be highly compressed to fit that much only 8 cds. A cd has 700 MB of storage. You have 8 of them. Do the math and that equals about 5.6 GB. If that's the case, you should probably get something that is at least 8GB. Go with 16GB if you plan on adding more.

prior to the day of the recordings
Prior to the day of the recordings:
  • Prepare your computer for the recordings by setting up folders relevant to the students – GCE / GCSE / Class 6E, etc. You will download your recordings into these folders.
  • You may want to copy in your student list into the folder or divide it into sections for ‘Morning’ or ‘Afternoon’ recordings

Day of Recording:
  • Once you are both ready switch on the device and give the appropriate information needed according to CCEA recommendations – Subject, level, candidate number etc.
  • Complete the recording with the student and then stop the recording or turn off the MP3
  • Your device will save the recording and assign a specific identification number – for example 0001 (this should have come to your attention when you were getting to know your device).

Day of Recording:
  • You will need to replace that specific identification number with your student’s candidate number and possibly a centre number

Transferring your files to CCEA
  • The following information is only a guide at this time and may be subject to change at any time in the future.
  • While the system for uploading sound files to the CCEA secure site is not fully developed yet it is envisaged that it could look similar to the current site used for ICT eModeration.

  • Assuming that this could be similar to the ICT eModeration it is likely that you will receive a ‘Pre-entry list of candidates’ file which you will download and update with student/centre information. It could look like this:

  • When you are required to upload your tasks the first screen you will see will look something like this:
