The dithering mode which will sound best to you is primarily dependent on the audio
material, and your personal taste. Audition the audio material with each of the
dithering modes to determine the right setting. In some cases, you may find that the
best results are achieved by using no dithering at all!
Important: Dithering the same audio signal multiple times should be avoided.
