Hi @audio-dav, Your first setup should work fine where you are using the QA401 DAC to drive a speaker and then capture that back into the QA401. The first link below is similar problem, but comparing a mic to a reference mic. But in your case, you can readily capture the chirp and compare to a mask.
For your question about loading a captured chirp into the QA401 software…that’s not currently possible but it’s a very reasonable feature request for the future (but not near term, unfortunately).
