When editing standard red book music CDs via my MBP and an editing program like Peak or Jam 6 adding crossfades, editing out sections and possibly adjusting the level of some tracks so a compilation from various CDs has consistent sound levels should dither be added? I have read conflicting info. I have Peak and that offers a dozen or more dithering options, confusing me completely. The manual is not helpful on this. As I understand it, dithering is to be applied when say, coming down from 24bit to 16 bit. So I assume on a 16 bit CD, dithering has already been applied. But then I read that dithering should be applied to any file after crossfading/editing it. Then... I read that dithering an already-dithered recording will result in loss of sound quality. Erk! I'm lost on this. Any answers appreciated.
