FAQ

About detect silence

How is this different from remove-silence?

detect-silence only reports where the silences are; remove-silence cuts them out. Detect first when you want to decide, remove when you already know.

Does it work on video files?

Yes. The first audio track of a video is analyzed; inputs with no audio are rejected with a typed error.
