In theory you'd need to dither every time a signal
is rounded to some representable value. That would
include intermediate results in filters etc.

In practice, as long as you stay in 24 bits or float,
most signals have enough noise on them (from analog
recording) or are complex enough to be considered
self-dithered (no correlation between the rounding
error and the signal).

I did some test to see the result of dithering years
ago. They are still on my website but there's no link
to them. Try
