Audio Sync Software?

I have lots and lots of separate audio and video files that need to be synced. Unfortunately, they are not the same length and it will have to be done manually. Ugh! I saw an amazing software at NAB that synced clips together with just a few clicks. I think it was in the $200 - $250 range. Has anyone heard of it or have a recommendation? This is for Adobe Premier software running on a PC.
Thanks in Advance!

The software you saw was probably PluralEyes:

Premiere can do this too, as can FCPX, but PluralEyes tends to be a little more advanced than the built-in versions.

My software:
Pro Maintenance Tools - Tools to keep Final Cut Studio, Final Cut Pro X, Avid Media Composer and Adobe Premiere Pro running smoothly and fix problems when they arise
Pro Media Tools - Edit QuickTime chapters and metadata, detect gamma shifts, edit markers, watch renders and more
More tools...

Thanks, I'll look it up now. If anyone has another software, for features or pice comparison, please let me know.
