Happy New Year!
You are the master of stuffing false claims ...
I mentioned Sam Berkow in another post. Do you know who he is?
Sure, you can find articles supporting pretty much anything. Does RTA provide useful information? Yes, if the user understands what he's getting.
Then why do the guys like Sam Berkow use dual-channel transfer-function measurement systems, which absolutely give phase information, when setting up studios and performance spaces?
