I got around to testing my NB/Scarlatti combination and trying to play DSD64 files that were recorded on my Korg MR-2000s.
Unfortunately, the only thing I heard was “low-level noise with faint music in the background”, as described in the support FAQ (“What is DoP (DSD over PCM)?”).
The FAQ describes the process as “taking groups of 16 adjacent 1-bit samples from a DSD stream and packing them into the lower 16 bits of a 24/176.4 data stream. A specific marker code in the top 8 bits identifies the data stream as DoP, rather than PCM. If something goes wrong…the output will be noise with faint music. This can happen if the computer erases the marker code by applying a volume adjustment.”
The Korg doesn’t seem to have the ability to allow me configure the marker to record with a volume adjustment marker or a DoP marker. I presume this functionality should be added by the NB.
It seems likely that the NB is not correctly setting the marker for DoP when it sends the data to my Scarlatti…
Is there a way I can pre-process that data through some transcoding program that will put the DoP marker into the DSD stream? Clearly, this will take some software skills…
My Scarlatti is running version 1.30 (and is set with DSD and AES downsampling, as above)
My NB has the following versions:
APP version: 1.0.2 (62)
Main Board Version: 1.02
Network Board Version: 1.0.2 (502)
