Can't disable DSD to PCM conversion

[David_Snyder]

@Marian

Roon must be converting DSD to PCM, performing DSP and then converting back to DSD.

No. It is not. But it is converting to 64-bit DSD. This post explains this somewhat, but there may be other posts that explain more thoroughly. The main takeaway should be that Roon is NOT converting to PCM.

Native DSD processing

Unlike with PCM, processing 1-bit DSD signals in their original form is not practical because 1-bit signals do not have enough dynamic range to perform common operations like volume adjustment, eq, mixing, or convolution directly on the 1-bit representation. So when DSD IS processed, the input to the processing chain is a 1-bit DSD signal, but the output must have more dynamic range. In Roon’s case, we perform processing with 64-bits of precision, so whenever you process DSD, you end up with so…
