I am a bit confused about the concept of dithering and would like some quick clarification. It is my understanding that dithering is used to help "smooth over" the digital artifacts that occur when going from 24bit to 16bit. Is this correct, or a gross oversimplification?
I ask because I'm currently working on a project using VSL Opus 1 (16 bit), Atmosphere (32bit internal?), and Stormdrum (24 bit transfered). If I wanted to bounce the files as 24 bit, do I need to dither at all? How about if I bounce as 16 bit, do I dither all Atmosphere and Stormdrum tracks but NOT the VSL stuff, as it is already 16 bit? If it helps, I'm using Logic 7.1.
Thanks in advance for any help and advice!
