You can probably change the size of the delta by
adjusting the amount and shaping of the dither.

But then how could the same dither Pow-3 cause different
deltas when applied in Samplitude and Sonar?

Same reason - different means of generating the pseudo random noise for
dithering.

Another reason - the details of the implementation of Pow-r 3 are slightly
different.

Samplitude -59.679 dB (consistently from one conversion
to another) Sonar -60.26 (consistently)

Not much of a difference in my book.

Also, when running 32 bit to 16 bit conversion with
dither in the batch in Samplitude, I get, on average, 1
out of 10 files with a glitch. The glitch looks like an
interruption of the sound with silence (with noise) for
about half a second. It is not exactly reproducible: each
batch conversion compromises different files. Could not
find any similar complaints on Samplitude forums or
Google.

That's a completely different issue that could have any number of different
causes.

When I convert without a batch - manually, file by file -
there is no such glitching.

Sounds the the batch mode stresses the machine over a period of time and
eventually it gitches.

Does this mean that batch processing uses dither differently than the main
program?

Not necessarily - the load on the system is different because the batch mode
just bangs away on the machine quite relentlessly.
