A FLAC verziókról szóló és a letöltéshez a linket mutató emailek kimentek. Hamarosan ki fog menni a DSD linkes email is.
Lesz benne egy meglepetés:
"Készítettünk továbbá egy DSD512 változatot is, a DSD256 eredetiből az igazán kisérletező kedvű zenehallgatóknak, szintén Hqplayer Pro szoftverrel “re-modulálva”. A “re-modulálás" jelentéséről és a DSD512 konverziós technológia értelméről az alábbiakat lehet olvasni a Native DSD honlapján:

"It is not possible to record in DSD 512, so how & why are these files created?
A conversion from a lower to higher bitrate contains no additional information over and above that contained in the lower. What it facilitates is the play-out DAC’s operation utilising gentler phase shifting reconstruction filters/algorithms in the D to A process. Recordings, regardless of their origin, do sound better on DACs which use Sigma-Delta modulators (the vast majority of current consumer DACs) as their conversion element. They’re less aggressive, more spacious, less “digital” sounding.
But, confusion appears to revolve around using the terms “upsampling and remodulation”. First, and foremost to our understanding, is that there are no samples in DSD. And there are no digital values represented in a DSD bit stream, as there are binary digital values of signal amplitude represented in the samples of a PCM word stream. In fact, DSD (or the more correct non marketing term, Pulse Density Modulation – PDM) is an analog signal itself, and not digital in the form most people understand and perceive the word “digital”.
PCM is a successive stream of amplitude samplings of the original analog signal, expressed as binary word values at some bit depth, and at some frequency. I like to think of it like a movie film; discrete frames of stand alone pictures chained together to yield motion when played out.
DSD (the 1 bit wide variant of PDM) is the process of modulating a bit clock (carrier) with an analog signal, such that the resulting modulation is a continuous stream of 1’s and 0’s bits of varying DENSITY, whose density is proportional to the original modulating signal amplitude. It’s of course more complex than that, but that’s the end result; a continuously varying bitstream of 1’s and 0’s bits, which when integrated by a DAC, removes the bit clock carrier yielding the original audio signal.
The primary achievement of DSD (besides its very high degree of fidelity and accuracy encoding the original analog signal) is its ability to be stored and retrieved into and from a digital computer’s storage elements. However, since this is a bit stream with no digital values represented (only a stream of 1’s and 0’s whose bit densities are amplitude proportional to the modulating analog signal), it can not be otherwise digitally processed using traditionally available processes.
Enter again the terms “upsampling and remodulation”. Obviously, if DSD contains no digital value samples, and in spite of being used universally, the term upsampling does not apply. The term remodulation is also confusing. There’s no “re” about it; it’s modulation, pure and simple. The fact that when the process is the modulation of an existing already DSD modulated signal, the end product has no accepted term to describe it other than Re-Modulation."
