Numbers games. I used to be good at those.
16 bit * 48000 Hz * 60 seconds * 60 minutes == 2,764,800,000 bits per hour
/8 (bits to bytes) == 345,600,000 bytes per hour ~= 350MB per hour
*2 (mono to stereo) ~= 700MB per hour (sounds about right)
Assuming Hz as a per second multiple. Not all that up on the techno babble.
((24 bit * 96000 Hz * 60 seconds * 60 minutes) /
* 2 ~= 2GB per hour

Going backwards based on resulting files.
12 minutes 41 seconds == 1,074,266,204 bytes (DSD @ 5.6MHz)
according to audiogate and windows explorer respectively.
DSD is supposed to have more dynamic range than 24 bit PCM. So lets call it 32 bit (or not).
12*60 + 41 == 761 seconds
1,074,266,204 bytes / 761 seconds == 1,411,650 (and some change) bytes per second.
1,411,650 * 8 == 11,293,200 bits per second
11,293,200 / 2 == 5,646,600 for mono (5.6MHz imagine that)
5,646,600 / 32 bit == 176,456 (and some change). Assuming 32 bit, still > 96kHz by the looks of it.
5,646,600 / 24 bit == 235,275 (even). ~= 2.4 times the rate of 96kHz. still greater than 192kHz. But there are PCM devices that do 384kHz now. And I'm not entirely sure of the bits spec for DSD when converted. 24 bit has greater dynamic range than 16 bit. DSD according to the Korg manual has greater dynamic range than 24 bit, so anybodies guess.
Stiill 200kHz is better than 96kHz? At least in terms of bits. Having a mic and source that uses that bandwidth? Does a PA system really use it? Versus something more acoustic like a stringed instrument or brass section? Does it matter if your mic or preamp doesn't send bits > 48kHz down the line? Can we expect a new line of HD microphones in our future? 0Hz to 192kHz versus 20Hz - 20kHz? Who knows a lot of it IS just theory. In terms of ADC / DAC, my Korg is the best I've got right now. It's converters are tops IMO. Even if it's not dealing in DSD.
