[IDEA] Polarity Flip

[Tim Curtis]

AFAIK, doing it on-the-fly while song is playing or doing it on a per song basis would require the feature to be part of MPD itself. Maybe someone could could post a feature request in the MPD Git :-)

There does seem to be some confusion as to whether the ttable coefficient is performing a phase shift or polarity flip. I think it must be performing a polarity flip when its negative because the coefficient itself represents a volume %. Its probably just confusion over the terminology.
