Plural Eyes does require a master track to synch to. It was originally designed with DSLR shooters in mind who capture high quality video but low quality audio. The DSLR provides the "scratch" track that provides the reference for Plural Eyes. Then it's just a matter of matching waveforms.
I plan to purchase the Windows version because I taped a conference last week and captured the best audio on my H4n. As luck would have it, one of the folks that organized the conference brought along a wireless mic system that I believe caused distortion of the audio in one of the cameras. Had I not used the H4n as the master track, I'd have had to rely on the two camera audio tracks, and one is useless. Be wary of these cheapo wireless systems. I don't know what brand it is, but I've tracked down where the interference came from and it is definitely from the wireless.
