Subject:OT: Sound Card rec/play Qs

I'm planning on getting a new sound card but don't understand a few things.

If I get a card such as the one below, as I understand, if I want to play back or record a track that is a certain resolution, say 44.1 then I need to set the box to the matching resolution, in this case 44.1.

(when I say box, I mean the external sound card/device)

But what happens when you try to playback a file using any ol' app, let's say a low quality mp3 in IE that is a lower resolution than the lowest box setting, in this case 44.1? Will it not sound on playback through the box?

Not that 192 kHz is terribly important to me, but, looking at the stats below under "Frequency Response" it doesn't list 192 kHz, so does this mean it will only record 192 kHz from an anolog source, but its really just upsampling 96 kHz to 192 kHz?

Thanks for your patience.

It may upsample the file on its own; I believe this is all dependent on the interface's drivers. (If you bring the file in ACID, I believe ACID will do the converting for you on the fly as well.)
