DXD is not new. It also is not an improvement on DSD.
DXD is how Pyramix workstations internally process DSD source files. DXD is what Merging Technologies and Sony/Phillips call 24bit/325.8kHz PCM. (Pyramix is a line of DSD workstation made by Merging Technologies.)
To mix and edit DSD, the Pyramix transcodes the DSD source file to 24bit/325.8kHz PCM for all editing. It transcodes it again back to DSD for output. That is, *all* DSD audio on a Pyramix goes through this conversion via internal PCM and sigma/delta converters.
SADiE (Sonoma) workstations do not convert the DSD source except at the edit crossfade point. During the length of the crossfade the DSD source is transcoded to 8bit/2.8Mhz PCM and back to DSD.
OF course there are arguments as to which sounds better. DSD purists prefer SADiE.
Thanks, but how do they work with the 2X DSD stuff showing up from EMM Labs, and a few others, Korg MR-1000 will record in 2X DSD, won't it? While the EMMLABS is upsampling it just on playback? Or is that what Korg is doing too, I ain't read enough about it yet, Then what works with that?
But I thought I read Pyramix is the only one that will do DSD, not any of the other software? Pro tools long the standard right, is obsolete?
