Normal/Inverted Phase Playback

[hkphantomgtr]

I can't think of a way to do this easily - a track based solution that is. Unless I write my own music player?

I believe it can be done in CamiilaDSP using a mixer to mix two signals where one has a negative gain (or inverted phase) with the other?  But I am far from an expert in this...

Thanks.  In fact, as there are getting lesser DAC and preamp offering Phase Inversion, I think if this can be done on the player stage then it'll be a very good news.
