16/44 converted from DSD- any way to tell?

My DAC is multibit, so any DSD files I have I convert to PCM 24/88.

Many of the SACDs I have are "hybrid" with a CD redbook layer as well.

What I am wondering is if there is anyway to tell if the CD redbook layer was done from the analog tape using a PCM converter or if it was down sampled from the DSD portion.

For instance with the RCA Living Stereo SACDs (older ones not the recent ones put out by Analogue Productions) I find the CD redbook layer rip sounds better than a 24/88 conversion from the DSD. Which leads me to believe the CD layer was done with a separate PCM converter.

SA-CD.net can usually tell you the provenance of the files. Or you can use Audacity or something to create an FFT.

I get that it's an analog recording/sourced from analog. My question is if the mastering team made a separate transfer to DSD and then PCM for the hybrid redbook portion. Or if the DSD capture was converted to 16/44.

I think using Audacity and looking at the files with FFT like you suggested will be the easier way to go. I take it I will be looking for high frequency noise creeping into the ~20k area of the 16/44 file.

It may be hard in a 44.1 Khz file to tell the origin being DSD. There can be noise shaping for other reasons causing a mild boost above 20 Khz.

Precisely my experience after going through several 16/44 redbook files. There is too little past 20k to make a meaningful assessment. I will continue to use the old fashioned listening method :)
