On some (conversion) software at least the (SACD) ultrasonics are preserved.

I've seen quite a few graphs of hi-rez downloads showing DSD-derived ultrasonic noise (which indicates the original recording was DSD). Hifi News has been publishing this data in their Hi-Rez downloads column for the past year.

I've seen the "noise dusting" showing the DSD ultrasonic noise on my graphs of files derived from DSD files, but here's a sample from the Ansermet disc, and I don't see it:

  I can usually tell with this type of graph (above), but cannot easily from the graph you posted (thanks).

    . . . here's one of my older posts which contains a graph showing the DSD ultrasonic noise (the last one in the post).

      Chris--Just use Audacity, which is free (link below). It's what I (and most others) use to generate the graphs that I post on Computer Audiophile. There are a few initial parameters that you'll need to set up (I can send them to you in a PM if you'd like) but once you've done that, it's very easy to use.
