resampling to 96 Khz 32 bit before pitchbending?

[Ubuntress]

Does resampling from CD quality (16 bit 44 Khz) to 96 Khz, 32 bit make
any difference in pitch bending quality?

Depends on how the algorithm is written, but if it's written well, probably
not.

A lot of DAW applications these days use 32-bit floats for all internal
representations anyway, so it doesn't really matter what the word length
going in and out is.

What might matter is the sample rate, and that could make a difference if
the filtering in the pitch bending algorithm isn't so good.

If you're simply using classic pitch transformation like where you
resample a stream, then filter and decimate, then I'd say no. It'll do
its own resampling.

If you're using something more like physical modeling as in TC Helicon
stuff, I don't know.

If you're talking Autotune or Melodyne, then I don't know again.
Try it and see.

Upsampling and increasing bit depth doesn't add any information.

Not very likely. Are you getting unsatisfactory results with a 44.1 kHz
file? How far are you trying to shift the pitch, and what tool are you
using?

What Les said. I asked about this at the Hydrogen Audio forum a while ago, and the experts there confirmed that good plug-ins will up-sample internally if needed.

But as Mike said, there's more than one pitch-management regime
available, and best practices may vary between them. I will
be biased to "batch" pitch shifting as per CoolEdit96 since that's
what I use. And in that case, they resample internally.
