What can I do with Audio Replacer?

Use Audio Replacer to add a music bed, drop in a voice-over, or replace poor original audio. It suits creators re-scoring clips and pipelines that standardize soundtracks across many videos.

Can Audio Replacer sync the new audio?

Yes. Audio Replacer supports an offset so you can line the new track up with the visuals. The each::labs tool then renders the replacement into the video, delivering a clip with your chosen audio in place.
