Your comment then wasn't clear because it sounded like you were objecting to the whole claim, but at any rate, I don't agree with your analysis, unfortunatelky I don't have time to refute it right now. Morse never used the term MP, he never does, no one in acoustics does, so I suppose my mistake was ever using it in the first place as I still contend, as I always have, that it is ill applied to acoustics.
I understand your position on the acoustics in the reverberant room environment, but I don't understand dismissing it in this manner. Without MP in acoustics to some extent, CAD software could not work as it does. It is true that considering specific individual axes does not provide the full story, but I would be hard pressed to find a way to do what I do if acoustics were not MP in certain aspects. Were acoustics completely non-MP in all aspects, I could agree with you. I see "ill applied" as being in the context in which you focus, not all aspects.

It's really important to use tools as they currently are, but also be aware the limitations of tools.

Say something meaningful, not platitudes.

So really, what do you wish to learn?

For one, whether it's possible to ask a question without inane posts by those with nothing relevant to say who seem compelled to say something, anything, just to be speaking.

The other item can only be answered by Earl.

The fact that minimum phase is ill applied to acoustics is true as Earl has mentioned. Since currently there seems no better way to apply acoustics characteristics into the design process, the current methods used in current tools are what we have to live with for now. I really see nothing more to mention unless more is desireable.

You answered item one above, I'll wait for Earl to respond for the other item.

Minimum phase is ill applied to all except a very small portion of acoustics. However, in many cases the non-minimum phase aspects are not significant enough to alter design consideration even though they show up in measurements.

Aha...and in which exact cases non-minimum phase aspects are not significant enough and which cases don't allow for non-minimum phase aspects? Please provide a listing.

Thanks, Markus
