The human auditory system is sensitive to absolute phase because the cells that generate signals from vibrations of the cillia in the basilar membrane are half-wave rectifiers.
Many sounds have asymmetric waveforms, especially voice, horns, and percussion. The audibility of these signals can be affected by absolute phase reversal if these sounds are prominent, and do not have any reverb. Many years ago, I listened to a double blind demo of absolute phase differences at an AES chapter meeting in one of the reference listening rooms at Dolby lab's headquarters in SF. And for many sources, the effect is not subtle. For others however, especially those with reverb or ambience, the effect is unnoticable. As a sound engineer for live sound, we learned to make sure the kick drum mic pushes the subs forward when you hit it. -- pbjbryan ------------------------------------------------------------------------ pbjbryan's Profile: http://forums.slimdevices.com/member.php?userid=3034 View this thread: http://forums.slimdevices.com/showthread.php?t=35708 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
