DSD to DSD conversion
« on: January 20, 2015, 10:40:10 am »
How does the converter works when converting from a dsd to dsd? It converts through PCM? And what happens when using DSP effects? For example gain in equalizer.

If you bitstream, the DSD passes through untouched.

If you don't bitstream, there's PCM stage in the middle that's 64-bit and high sample rate that handles all the effects.

Matt - in another thread it was said that converting a dff file to a dsf file went through a PCM conversion. Is that in fact the case? If I understand correctly, both formats have the same data chunk, so it would seem that just changing the header would not require a PCM conversion. This becomes an issue since some DSD downloads are in dff format and most people would not want a PCM conversion to simply convert to dsf to add tags. Thanks for your insight.

Matt, I was talking about converting, not about playing. For example DSD256 in DSD128.

We have a PCM stage in the middle of the format converter.  I don't recommend it for DSD to DSD conversions.

Thanks for the clarification, it's all I wanted to know.

maybe a direct DSD->DSD or SACD->DSD conversion (aka "bitstream") without the intermediate PCM stage could be considered?

Unfortunately, such a conversion does not fit into MCs current architecture at all, so the chances are rather slim.
