Crossfeed in 1.3

Hi

This is just a question about crossfeed only.

I have it turned on and I have all other DSP turned off (up-sampling off).

I understand that Roon 1.3 converts everything to 64 bits for crossfeed but is it also doing noise shaping at higher sample rates, with my up-sampling setting turned OFF?

Or does it perform crossfeed DSP at the original sample rate only?

If I turn up-sampling setting ON does this enable crossfeed and noise shaping at a higher sample rate?

Thanks again

Roon does not apply sample rate conversion unless upsampling is turned on or downstream compatibility requires it. Roon signal path display tells the story.
