Oh, that is impossible without adding an ASRC to the USB module, as the output is a function of the PCM2707.

So even if your feeding the I2S into the Opus no 24bit? Gotta have the metronome in place and then it will do 24bit 192khz?

No it has nothing to do with the DAC. The DAc can do 192/24 no problem.

It is just a limitation of the PCM2707 USB module. That module can only output 44.1 or 48khz.

The Buffalo DAC will easily do 192/24 either PCM(I2S LJ/RJ) or SPDIF.

Ok I get that part but what I'm asking is that with the Metronome will it do 192khz? And also will the PCM2707 do 24 bit or only 16bit? Sorry if we're frustrating you I just was thinking with the USB module I would be able to do 24bit at least.

The metronome can convert the 16bit to 24bit yes. but there is no need, since the ESS DAC already basically does the same thing (only better). Just feed it the I2S out of the USB module.

Cheers!

Well for the time being I'll be using the Opus so thats why I was curious. It can't take 24 bit directly from the PC I guess kind of sucks... Maybe I should have went with SPDIF

Default USB

Hi All,

Yes you could just use the SPDIF output from your computer and drive it into Russ's board for a 24 bit, source, but I think everyone knows this. I am curious as to who has made USB do 192kHz and 24 bit depth from the computer since that is was we did for the demo boards. Anyways, how are the design's going?

24 bit USB is pretty necessary... at some point..
You can download 24 bit files right now, so it would be nice to listen to them...

I agree but looks like it's not much of an option right now. I'll probably just do SPDIF out eventually when I order that board.
