Review and Measurements of QuantAsylum QA401 Audio Analyzer

Hello,

I look back in this thread and see that @edechamps wrote the AISO driver for the QA401.

How do we support the development of the QA402 ASIO driver?

Thanks DT
 
Well you don't have to wonder anymore, because it's done now! (Sorry for being 3 years late to the party…)

Hello @edechamps ,

Thanks, I thought that you went on to other interests.

I will download your AISO driver and give it a spin with the QA403 and AP500 Flex software.

Thanks DT

There will be partying and dancing in the street!

Noise measurement of the QA472 Mic Preamp.
I was curious about the difference between PRE1 -> PRE2 and PRE2 -> PRE1.
