FAQ

About normalize audio

Which target should I pick?

Use streaming (-14 LUFS) for YouTube, Spotify and social platforms, podcast (-16) for spoken audio feeds, and broadcast (-23, EBU R128) for TV delivery.

Does it work on a video file?

Yes. The video stream is kept as is and only the audio is normalized.
