when to add dither?

[Melody_x]

for example, if I wanna truncate a piece of audio from 16 bit to 14 bit, when should I add dither?
before or after truncating?

by the way, I'm trying to do it in C, not with any software:)

Melody,

You might get a better response in the DSP and Plug-in Development part of the forum.
