The ability to sync audio files is already present in PowerDirector's MultiCam Designer feature.

I'd like to have that same functionality in AudioDirector: to be able to input more than one recording of the same audio event and have the ability to sync them all automatically and be available for mixing.

In my work, I often have access to multiple audio recordings of the same event, from different microphones in different locations. I'd like to be able to mix them to improve the ambience and overall quality.
