 # Command to lower the bitrate of an mp3 using FFMPEG

 # Options:
 #   Low: 96k
 #   Medium (Radio quality): 128k
 #   Medium-High (CD quality): 192k
 #   High: 320k

 # "Converting an MP3 to a higher bit rate does not add any more
 #  audio information to the file, so the sound quality does not
 #  increase. Converting an MP3 to a lower bit rate reduces its
 #  file size, but may also introduce audio artifacts, as the
 #  encoder is compressing an already compressed file."
