Title: Volume gain for DSD
Post by: bg on July 10, 2019, 07:52:49 am

Realize Apple never embraced DSD (or Blu Ray). How to set volume gain on DSD recordings to closely match volume levels on PCM recordings? Thirty percent of my recordings are DSD.
Using Core Audio on version 25.0.50 for Mac. Don't want to purchase Windows notebook.

This is complicated.  Apparently DSD is recorded 6 dB below the normal standard for PCM.  See a little discussion about this here:

It's complicated because if you want "pure DSD" then you don't want it converted to PCM.  So you want the un-altered signal sent to your DSD DAC.  Which means you can't change the volume in MC, because that would convert it to PCM, and then back to DSD, making it "no longer pure".

If you don't care about that, you can convert DSD to PCM and do volume leveling on it.  Or set the "+6 dB" switch that Matt talks about in the thread above.

Good luck.
