I am using it for wide-frequency viewing, which is why I made my request as such re: 192kHz. I definitely want a 24bit card for the reasons you mentions. You also have mentioned the noise floor - this is very important to me. I'm often operating in non-optimal conditions, so every little bit helps.
I posted requesting feedback on 192kHz sound cards (I should have specified 24-bit or better) specifically for a reason. You've basically hit the hammer on the head for the reasons. :) As to the falloff, can you point me to a thread so I can understand it? If it's something the PX3 (which I also own) compensates for, I can probably write code to do the same in my favorite applications. I very much appreciate the input, David On Tue, Nov 11, 2014 at 8:08 PM, Don Wilhelm <[email protected]> wrote: > David, > > A regular 16 bit soundcard will do well when being used for digital > modes.
