Convolution vs Parametric

[David_Snyder]

Any DSP has to be applied in PCM , same as parametric. Roon will always convert source to PCM then apply DSP then back to DSD regardless of PEQ or Convolution

Hmmm…are you sure? I need to connect a DSD DAC again, but I’m fairly certain that the wizards at Roon Labs came up with a way to apply convolution and other sorts of DSP without a round-trip through PCM. I’ll re-test and get back to you.

Update: Yes. No round-trip through PCM:

In the meantime, have a look at this thread…

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…
