Nah, when they say "mastering," they are talking about the studio process of mucking around with the originally recorded tracks, downmixing to stereo from multitrack, etc. While digital studios may keep most of that in the 24/96 or 24/192 format, it all gets downsampled to 16/44.1 before getting dumped on a CD. So, there isn't a "master copy" of a CD in a higher resolution format... When you find those CDs that say, for example "Superbit 22 bit format", its saying that the CD was mastered using 22 bit "words." You aren't getting some odd 22/44.1 format on what you are buying--its still 16/44.1.Dawnrazor-What kind of DACs deal with 32 bit formats? Are you sure you aren't talking about upsampling to 24bits? 24/96 and 24/192 are fairly common, but I haven't seen 32/96.

ED,The lynx 2 is one of those "prosumer cards". It supports up to 32/200. Although pricey (why is it that audiophiles will easily spend $2-3K or more on a cdp, but get cheap as hell when it comes to PC audio balking at a $1k sound card...and expect it to sound better tahn their 3k CDP?) I figured that it handled high enough sampling rates and frequencies, to be future proof for a long while. I can always get another computer if I need to go to those levels, or a new format comes along.
BUt The max I can do is 32/96 since I haven't found an upsampler that goes higher. Well, I CAN create files with db power amp that are 24/192 and then the computer doesn't have to do the heavy lifting realtime, but that is a ton of space, and I am not sure it is worth the time effort and money to do so.
Foobar has a setting to output 32 bits, and I usually have it set to that.
Do you know of an upsampler that goes to 192, or 176?
So are you using the analog or digital outputs of the Lynx? Guess I was wondering what DAC could chew a 32 bit input. I've got a hardware upsample (dCS Purcell), so I haven't messed with the software upsampling in foobar...
BOTH.Analog to the amps, and for head phone listening I run out to a Birdland Dac...which apparently has no problem with 32 bits.
I am assuming it is putting out 32 bits as foobar reports it, and the lynx mixer reports this as well, but I don't know for certain.
***Do you know of an upsampler that goes to 192, or 176?***Dawnrazor -
I thought you said you used "Secret Rabbit" (SRC) resampler in foobar. I'm pretty sure you can change it to 192 or 176. I know the preset numbers only go up to 96, but you have to manually type in the value if you are going higher. (192000 or 176400) Just be sure you stop any music that's playing before you do this. It freaks out if you do it while it's playing.Give it a try. Let us know how it works. It's going to take a lot of CPU power though.
It doesn't work, as you rightly say, it requires a ton of processing power. My little 1ghz machine can't do it at those rates. I think it got up to 88 with some stuttering using the SRC upsampler.I did just try playing a 24/192 file that I made on another computer using db poweramp. Foobar refuses to play it on version 09.3, but 08 will play it, there is just no sound.
My lynx software reports 192 for the clock rate on 08, there is just no sound.
SO maybe Foobar doesn't really support 192???
