Has anyone done tests on ADCs with the QA403? I’ve done some tests using a Scarlett Solo as a DAC with the 403, and now would like to check the Solo used as a ADC.

Any ideas?

Thanks,

You can import .wav files into the QA-403 and analyse the data.

You need the sample rate match and both channels.

I wanted to analyze some test CDs, but 44.1kHz isn’t supported in the QA software. That is unless there’s a command line option (like the -384k) I don’t know about. Maybe @matt can advise.

Thanks for the info. Got the 403 two months ago and still feeling my way around it.
