is it even possible to hear "Phase distortion"? 2018-12-18 09:42:58 I came across a dude who thinks he can hear phase distortions made by an equalizer. Putting aside differences in loudness of different frequencies, this means he should be able to hear differences made by an all-pass filter. I doubt he will prove it even if he could. But I am pretty sure this difference is impossible to hear if tested correctly (so, for example, signal after filtering doesn't clip, etc).I tried to search the web a bit and could not find if anyone succeeded in detecting an all-pass filter by ear in a blind ABX test.Should I immediately dismiss this dude as yet another placebo troll, or he might actually have golden ears?
