The easiest way I've found is to listen at moderate level with your hands cupped behind your ears. If the phase is reversed the sound is better with your hands there. If the phase is correct, the sound is worse. (Either way, adjust for the added apparent volume.) There are other aural clues, but that's the easiest way I've found. Try it.
How to tell if lp is recorded with phase reversed?
I'm just wondering what is the best tipoff that an lp is recorded with phase reversed. I have a PS Audio GCPH, so reversing phase is easily accomplished. I have listened both ways, on some lp's it seems to sound better with phase reversed, but what are the obvious signs, or are there any? Thanks, Dan
