AI Sound Effects Generator – Foley and Score for Your Clip

What the sound studio can do

Foley for a clip, a score for a clip, effects or music from text — and the controls around them.

Generate now

Sound generated against what is on screen

Upload a clip and get effects made for that footage — footsteps on the footsteps, the door on the door. The result comes back as a finished video with the audio already muxed in, so there is nothing to line up in an editor afterwards.

Music written to the cut, section by section

Score a clip instead of dropping a loop under it: describe what each stretch of the video should feel like and the sections are generated as one continuous piece across the whole clip. Same output — the muxed video, ready to post.

Standalone effects and music, no video needed

Two of the four modes need no footage at all. Describe an effect and get the effect; describe a mood and get a piece of music. Useful for building a library, filling a gap in an edit, or auditioning an idea before you commit a clip to it — and both are billed at a fraction of the video modes.

AAC, MP3, WAV or FLAC

Pick the format the next tool in your chain wants: AAC by default, MP3 for the quick share, WAV or FLAC when the audio is going into a mix rather than straight to a platform. Source clips up to 500MB and five minutes long.

Prompt each moment, not the whole clip

Split the clip into sections and give each one its own line of direction: gravel underfoot here, a door closing there. Sections have to run at least five seconds, each prompt is capped at 200 characters, and the last section is pinned to the end so the whole clip stays covered. Leave it switched off and the model splits the footage into scenes itself.

Keep the voices, score around them

Preserve speech separates the talking in your clip and writes music around it instead of over it. You can also score one stretch rather than the whole thing: set a start point and a length, and only that section gets music. Both switches sit on the music side. The sound-effects pass has no equivalent, so test a short clip first if the dialogue cannot be lost.

Hear it against the original, then take the stem

Every result opens on the generated version with a one-tap switch back to your original, so you can hear exactly what changed before you commit. Under it sit the downloads. A sound-effects pass hands back the finished video and the generated audio as a separate file from the same render; a music pass returns the video, or the bare score if you asked for score only.

How 7ART compares

Frequently asked questions

• How is it priced?

  Per second of the source clip, with a 15-second minimum. Adding sound effects or music to a video is 1.8 credits per second, so a 30-second clip costs 54 credits and a 4-second clip is billed as 15 seconds. Text-to-sound-effects is 0.36 credits per second and text-to-music is 0.5, both against the same 15-second floor. The duration is measured on the server from the file you upload rather than taken from what the browser claims, so the quote and the charge agree.

• What are the limits on the clip I upload?

  Up to 500MB and up to 300 seconds — five minutes. Longer clips are refused rather than silently truncated. For the two video modes the billable length is the whole source clip, including when you scope music to specific sections, because the render still returns the entire video.

• What model runs it, and what happens if it fails?

  Sonilo v1.1, running on fal — fal is the exclusive partner for this model, so there is no second provider to fall back to. Rather than pretending one exists, a failure surfaces as a failure and the credits go back automatically. That includes the awkward case where the job reports success but returns no media, which we count as a failure and refund rather than leaving you charged for nothing. On a Music and Sound Effects run the two passes are billed separately, so if the second pass cannot start you keep the finished score and were never charged for the pass that did not run.

• Do I get a video back, or just an audio file?

  For the two video modes you get the video with the audio already mixed in, so it is ready to post as-is. For the two text modes you get an audio file in whichever of AAC, MP3, WAV or FLAC you selected.

• Can I use the audio commercially?

  7ART's terms permit personal and commercial use of generated content, subject to those terms, applicable law and any restrictions the underlying model providers impose, and the rights available to you vary by country. Downloading the output requires a paid plan.

• Can I combine it with video I generated on 7ART?

  Yes — that is the common path. Generate a clip in the Video studio, bring it here to add foley or a score, and the muxed result goes back into your library. The creative agent can also plan the two as one chained job so the video renders and then gets its sound in a single approved run.

• My clip already has dialogue. Will the generated sound wipe it?

  On a music pass you can switch on Preserve speech, which separates the talking in your clip and scores around it rather than over it. The sound-effects pass has no equivalent switch, so if the dialogue cannot be lost, run a short test before you commit the whole clip. Your source file is never modified either way. You always get a new video back and the original stays in your library.

• How long does a generation take, and can I close the tab?

  We do not publish an average, because it moves with the length of your clip and how busy the provider is. The page checks every few seconds for the first half minute, then backs off to longer intervals. Reload and it picks the same job back up. If nothing has landed after twelve minutes the page stops watching and tells you to check your library, where a late result still shows up.

• Do I need to know sound design to get something usable?

  No. On a video you can leave the direction box empty and the model works from the picture alone, and leaving segmented prompts off lets it split the clip into scenes itself. For the two text modes there is a dice button that drops in a fully formed prompt, plus worked briefs for common jobs like a product ad, a channel intro or background music.

• Is the generated audio watermarked?

  No. Nothing is stamped into the audio or into the video that comes back. The free-tier "Generated on 7ART.ai" watermark is baked into images only, so sound and video outputs are clean on every plan. Downloading the files does require a paid plan.

• Can I get a seamless loop for a game or an app?

  Not directly. There is no loop switch here. You set a length, up to three minutes for an effect and up to five for music, and get a one-shot render. If it has to loop cleanly you will need to trim and crossfade it in your own editor. For ambience under a video the two video modes are the better fit anyway, since they cover the whole clip end to end.
