Title: DSD conversion - what's happening?
Post by: Bibo on October 27, 2013, 10:22:35 pm
I have some DFF files from Blue Coast Records.
In v19 I noticed that it is possible to not-on-the-fly convert to DSF DSD, so I decided to have a go.
All files are converted to .DSF format which allows metadata tagging. All files except one (why?) have 4 bytes more compared to the orginal.
However, something strange is going on.
1) Volume on the converted file is lower than the original. Has it received a -6dB?
2) Some files present a loud TOC during transition with the next file. If the file is played on its own, no "toc" is present.
I tried to convert 2 albums and this happens on 40-50% of the files. However, it seems that by reconverting the same file I may be able to get rid of the noise.

My questions:
Is DSD conversion meant to be used for PCM -> DSD?
Can I use for DFF -> DSF?
What about the "strange" behaviour I found?

I would not recommend doing that.

It will convert to high sample rate PCM (probably 352kHz) and back to DSD.  This is because the converter is PCM only.  This is also why you're experiencing #1 and #2.

Thanks for your reply. Good to know.

For conversion DFF -> DSF I have just tried Audiogate and it is perfectly fine.
