Re: The problem with all this...


Absolute phase is always changing, anyway, as the signal moves through the air.

Actually the proper term is "absolute polarity" not "absoute phase."

Absolute polarity refers to the polarity, in terms of compression/rarefaction, of the sound waves produced at the original acoustic event. And whether at the origial acoustic event or played from loudspeakers, the polarity of the signal doesn't change but remains the same as it moves through the air.

"Absolute phase" seems something of an oxymoron given that phase is a relative term. So when you say that phase is changing as the signal moves through the air, what do you mean? Relative to what?

Sure, if you measure the signal at some point distant from the speaker relative to the signal at the speaker, there will be a phase shift due to the time it takes the signal to propagate that distance, but I don't see what that has to do with what's being talked about here. position.
