It's not possible to hear absolute phase - because it's not there to hear. Why does everyone assume that a CD is in "correct phase" in the first place? Aaaaaargh..... 1) There is very little chance that correct phase of all instruments/tracks has been preserved all the way through the recording chain 2) There is every chance that some tracks are deliberately or accidentally phase inverted (expecially live recordings - the phase will often be flipped at the desk to reduce feedback) 3) The ONLY instrument that even remotely "might" have a phase to preserve is a bass drum - when the skin moves out on first beater impact the speaker cone should also move out...however, no drummer I know can tell the difference if you invert the phase of a solo bass drum track...and you'd think they would notice? In fact I'll go further, I've never - in 25+ years of messing around in studios - heard any singer or musician notice "correct" phase. There is a reason why those desk channels have a phase invert button...but it's nothing to do with "correct" sound reproduction. It's there for very valid technical reasons that crop up from time to time. If you think FW15 sounds better than the current FW (and I certainly don't) then fine - but please don't ascribe this feeling to anything to do with preservation of absolute phase. Regards Phil PS if you want to prove this, try creating an RC impulse response curve with phase inverted and compare with non-inverted... -- Phil Leigh ------------------------------------------------------------------------ Phil Leigh's Profile: http://forums.slimdevices.com/member.php?userid=85 View this thread: http://forums.slimdevices.com/showthread.php?t=35274 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
