MP3 has become a very popular format for audio, particularly in the sale of music online through providers such as Apple iTunes, and music subscription services such as Spotify. It is important for an audio professional to understand that file compression has an impact on the overall sonic quality of the original audio file. To complete this task, you will need to: ? Find a song of your choice, it must be 16bit 44.1kHz ? Using ProTools, convert that song into the following MP3 bitrates – 320Kbps, 128Kbps, 64Kbps ? Import these converted files along with the WAV file into a ProTools session ? Conduct a listening analysis and evaluation of the original song against the converted MP3 files. Some things to consider: ? How the original file sounds compared to the file compressed versions ? Has the frequency content differed in the file compressed version compared to the original WAV file? ? Do the instruments sound any different in the file compressed versions? ? Is there a difference in loudness at all? ? Is there any change to the stereo image of the song as it is being file compressed? Submission Requirements Part 1: Data disc containing the ProTools session, with the original WAV file and the 3 converted files. Part 2: 1000 word production journal documenting your evaluation and findings for each converted file, with accompanying screen shots to support your result.
