AUTO SYNC dual audio in resolve

Hello everyone , maybe anyone here can tell me how i can auto sync The audio from an external recorder with the audio of my Bmcc in Resolve 10? I found some sync features but was only for time coded audio.
Thnx a lot.

You can only auto sync where the picture and the audio share the same timecode. If your audio is just time-of-day code, you must manually sync your picture. There's a tutorial for that in the manual. If you want to auto sync off of waveforms, use a program like Pluralize or the built in versions in NLE's like FCPX.
