Crossfade clicks in DSD projects

Postby green-qqq » Sun Mar 17, 2019 22:21

I have Pyramix Native and I am getting clicks in the start (and stop) of crossfades in dsd projects. The clicks disappears when i render the dsd.
Is this normal in Pyramix Native, as the files are converted to DXD in the crossfade area? Or does it have something to do with my sound setup etc.?

In a DSD project, Pyramix is only working in DSD-mode, so there will be clicks at edit points because there is no *real-time* conversion to DXD. As you correctly note, the clicks go away when the file has been DSD-rendered. If you want to avoid this behaviour, convert your project to DXD, do your edits and then convert the project back to DSD and DSD-render the output files. There is a command in the settings to invoke the 'Ask for DSD / DXD project conversion on opening' and that may be turned off by default these days (I don't remember...)

Thanks for the answer!
I only use the "pure" dsd in simple project with only a few crossfades, and then it's okey with the clicks as a long as I get as little conversion as possible. As I understand, only the crossfades area is converted to DXD, the rest is untouched.

Is there a reason why DSD projects are not "real-time" converted to DXD, and then remain "clean" in the rendering?

If I am not mistaken, the only system that was able to do the math while remaining true DSD was the Sonoma system. Before Pyramix was stable with DXD (we started with PMX4), we were running Sonoma for all DSD / SACD title requests. No other system can do the math necessary for any sort of processing in DSD. This is why merging went with "DXD" which is basically ultra resolution PCM - which can be processed (ie. edits, EQ, fades etc...). No that Sonoma has not upgraded beyond XP, Merging has the market - and we live with DXD.
