Can't use Roon upsampling DSD

[wklie (Peter Lie)]

Just like to add a DSD256 upsampling data point for processing speed using i5-6600 CPU (music from local HDD) for Linux Build 209:

192kHz -> DSD256: 1.2x for Minimum Phase, 1.3x for Linear Phase

I’m slightly surprised to find that the phase affects it, while 5th / 7th order setting does not seem to affect the processing speed in my test, unlike a previous report:

Sample Rate Conversion and hardware limitations

Also for comparison purposes, I run Roon Core on a mid-2011 i5 Mac mini, and I can upsample to DSD128 with the 5th-order modulator. If I try to use the 7th-order modulator, I get stuttering, and if I try to upsample to DSD256 … I can’t. Edit: I should mention that since I’m going to a Linux-based endpoint (exaSound PlayPoint), I’m not using DoP.
