Yes, because I have been an auido engineer for over two decades now. Show me someone who can reliably pass the iTunes test. Science does not care about your subjective personal experience.

I highly doubt that. Do a proper ABx test (such as the one on digitalfeed.xyz) I have yet to meet someone who can pass the tests with a reasonable degree of accuracy.

I dont see why you can’t just use the hdmi output on the camera + any capture card.
