Rode Promotion: Free software
Let me first say: I am not affiliated at all with Rode, or the makers of PluralEyes. I do, however, love Rode's microphones and own a few of them., and am a regular PluralEyes user, and think the software is awesome and a huge time saver..
Hence, let me please point you to a promotion Rode has going where they give away a copy of the PluralEyes3 software with purchase of a VideoMic. If you are planning on buying one anyway, this is an awesome change to score some really great sofware at the same time.
