Dithering question

This is a bit of a newb question, but here goes:

I have a few tracks produced and exported in 32 floating point resolution. I now need to dither those files to create 16 bit masters for CD. I have the Apogee UV22 on my master stereo out channel in a post-fader slot set to 16 bits. However, after the mixdown, the file is still in 32 bit FP resolution.

Do I have to select the 16 bit option on the audio mixdown screen to have the file in 16 bits, and if so, is dithering to 16 bits still applied?

Any input will be greatly appreciated.

Short answer: Yes and Yes :wink:

Thank you DeadAgain, much appreciated.
