Sound is the AI sound effects workflow for creating short audio layers that match a video moment. It is useful when an edit needs impact, ambience, Foley-style details, interface sounds, transitions, or a quick sound design pass before the final mix.
Kepler keeps sound generation inside the video editing workflow. Generated audio is added as new media, so the original project audio remains unchanged. You can trim, move, mute, layer, compare, or remove each result on the timeline like any other audio clip.
A typical workflow:
- Open Sound from the Generate menu.
- Describe the sound effect, texture, timing, intensity, and environment.
- Choose duration and model options when available.
- Review the credit cost before generation starts.
- Add the generated sound effect to the project.
- Place, trim, and mix it against the video timeline.
Good sound effect prompts describe both the source and the edit context. Instead of only writing a label like explosion, whoosh, click, or ambience, add the material, distance, room, movement, intensity, and whether the result should feel clean, cinematic, subtle, dry, close, distant, or layered.
Can you generate sound effects for video online?
Yes. Kepler Studio runs in the browser, so you can generate sound effects for a video project without installing a desktop editor. The generated audio becomes editable project media instead of a disconnected download.
Can AI sound effects be placed on a video timeline?
Yes. Kepler is built around timeline editing, so generated sound effects can be placed near the clip or moment they support, then trimmed and mixed with other audio tracks.
Do generated sound effects replace original audio?
No. Sound generation creates new audio media. Original clips, dialogue, music, and imported audio remain unchanged unless you choose to edit the new result into the timeline.
