There are two newer USB audio inerfaces.
BEHRINGER U-PHORIA UMC202
and
Focusrite Scarlett 2i2 2 In/2 Out USB Recording Audio Interface
Which one would be better for using with ARTA and other similar software ?
I'm expecting someone to have tried them already.
Thanks.

I have the 2i2, but not the umc202. If you have any other questions or want any other measurements let me know.

Thanks for those measurements Nyt.
I didn't check the thread for a while. Looks like no one with the UMC202HD has responded. I guess someone must be using it ?
It looks like the Focusrite is a shade more expensive than the Behringer.
The UMC202HD goes up to 192Khz. The Focusrite is 96K hz .
Strangely I don't see any specifications for the Behringer anywhere ! Like just a vague 'super mic preamp' designed by Midas. No numbers.
Hope someone with the UMC202HD will post their experience with this unit. Behringer claims it's 'built like a tank' ! 🙂

Will the 2i2 work with XP? For some reason, I feel like I read the specs and it stated Win 7 or 8. No XP support.
Thanks.
Thanks.
not noise
This is not noise floor! Don't make mistake.This chart is averaged many times, so real noise floor is a lot more than that. In example in ARTA there is RMS signal level showed in bottom left corner. With no input it shows exactly RMS noise level of your sound card
And noise floor

It is actually the noise floor. But the RMS noise is of course not -145 dB. Probably more like -100 to -110 dB.
I have attached a couple of measurements I made some time ago. I used averaging to make the noise floor more smooth, so that it is possible to see if there are discrete noise components, like 50/60 Hz + harmonics or some noise from digital clocks etc.
Increasing the size of the FFT window size is also useful, as shown in the last figure in the attachment. It reveals some faint noise components at the upper end of the frequency range. But it does not change the RMS value of the noise floor. The noise floor is lower, but there are also more bins to add in the RMS calculation, so the end result of the RMS value is the same. In this case there is actually a 0.1 dB difference, but that is just a small random variation.

UMC202 has more distortion than one would want for certain types of measurements - I think its from the "MIDAS" input section (these are loop measurements) - if I'm using RMAA properly (?) then here's what am seeing.
btw. dynamic range did not improve at 2496
THD inputs at 5 o'clock
THD inputs at 1 o'clock - you can see things aren't properly settling and there was a warning of interchannel interference which I could not influence for the better
there seems to be a HF spike which is compromising things - is it an internal oscillaiton? - from my laptop?

and here is the location of that HF spike - its compromising the signal to noise floor
what would be its source?
