I record video with my camera and separate audio with an audio recorder. The video consists of several files (because of the 30 min limitation and sometimes a battery switch) and the audio is just 1 file. Now I am looking for free or not too expensive software to synch the separate audio with the video files. I would prefer to keep the audio file as it is, which would mean that there would be some gaps in the final video file. I hope some people can help me with this. Thanks!

Myself i do this all manually by hand in Sony Vegas Pro.

I have heard others use Plural Eyes to do this automatically.I have not used it though.

Exactly the same for me.  For starters, even with modern recording equipment, I often find that the audio runs slightly faster or slower than the video (maybe 3-4 frames in a one hour video).  That doesn't sound like much, but it's the difference between the drummer's drum stick hitting the drum on the beat and the stick being held up above the drummer's head at the sound of the drum beat.  Furthermore, there is almost always a difference in the sync between the video and audio unless the video has been shot from really close to the stage.  Various other issues as well.

IMO - the only way to truly get everything synced perfectly is by using your eyes and ears.

I used to sync everything manually.  Sometimes it took literally hours (I can tell if it's off by only one or two frames).  Fortunately now Final Cut Pro X has automatic syncing capability.  I can take a two hour hour video file and several audio files, or conversely a long audio file and multiple video files, select them all, hit "sync" and a few minutes later it's done.  Magic.  It's accurate, too.  Once that's completed I can adjust for sound delay if necessary, easy to do as that is constant throughout the show.
