I only have a need to use them when I am mixing other engineer's recordings. I do try to phase align, and make the source sound good with my microphones BEFORE pressing record, not try to salvage a lazy mic placement after the fact.

I do have the Little Labs IBP under the UAD label, and also the Waves "InPhase" plug in as well.

Now as to "phase" vs. "polarity" :

Phase is commonly misunderstood and confused with polarity. Phase IS 360 degrees of a signal within a transmission line. Polarity is either the negative or positive poles in an electrical circuit. Only negative or positive, two states, as opposed to 360 possible states of phase.

Howling at the neighbors. Hoping they have more mic cables.

I use the Melda often. The topic can be a can of worms, though. It's not always possible to fix the issue in analogue or the real world. For example, multing a guitar and bringing the mics on the different amp/speakers into alignment is tricky if on one path there's something digital with latency and you have the band in the room... one mic is half a feet from the cab, the other should be three feet away to cope with the other lines latency. Without having more spill on that mic than speaker.
Then polarity and phase aren't put into stone on everything - in a signal, different frequencies may have time differences and phase differences at the same time and you may have a different distribution if you put your mic here... or there. So all the methods will work better with some signals and less with others. It's handy to have them around to try.

I have the hardware and software ibp's, and though I don't use them all that often, when I need them, they're great. There are cheaper options, but since I already had the ibp when the others came along, I haven't tried them.

It's easy to go down the rabbit hole when something's just "medium" out of phase, as it can be hard to hear what the best possible solution is. I extrapolated some Steve Albini advice into the method of making it sound as bad as possible, and then flipping the polarity 180 (not that I'm claiming to have invented that technique or anything).

I have the UAD IBP and also don't use it very often, however I used it this week on a recording that was 2 mics on acoustic guitar and another on vocal. Nothing was really out of phase, but there was some bleed in the vocal mic (and in the guitar mics) because it was all recorded in one take. I put the IBP on the vocal mic and just moved it around - it was really interesting how it could affect the entire tonal balance of the tune.

I bought Audiomere Polarity Maximizer about a year ago and it rules. Super easy to use and saves on time. Totally worth the $50 they ask for. If you use Harrison Mix Bus as your DAW it come built in. Pretty rad!
