ElevenLabs SFX v3: How to Make AI Sound Effects for Video in 2026

Sound is half the picture, and it is usually the half that gets rushed. ElevenLabs SFX v3, the new text to sound effects model that ElevenLabs rolled out to every workspace on November 2, 2026, is built to fix the biggest weakness of AI foley: prompts with several sounds in them. Describe footsteps, a door and a distant siren in one line, and v3 is designed to actually give you all three, in order.

Here is what changed, what it costs, how to prompt it like a sound designer, and where it fits in a real edit.

What Is New in ElevenLabs SFX v3

ElevenLabs itself calls v3 an incremental update, and that is a fair description. You are not getting a new interface. You are getting a model that listens to your prompt more carefully. The three improvements that matter for video work:

• Layered prompts: several actions in one prompt are followed more reliably, so a whole beat of foley can come from one generation
• Voices and music inside effects: crowd murmur, a radio playing in another room or a vendor shouting now sound more natural
• Cleaner highs: fewer clipped, crunchy peaks on bright sounds like bells, kettles and wind chimes

In the app, v3 is already selected for you. On the API, set the model ID eleven_text_to_sound_v3 on the same sound generation endpoint you used before, which makes side by side tests against v2 easy.

SFX v3 vs v2 at a Glance

Feature	SFX v2	SFX v3
Status	Deprecated, removal March 1, 2027	Default in the app
Prompts with several sounds	Often drops or blends events	Follows the sequence more closely
Vocals and music in effects	Weaker	Improved
Seamless loops on the API	Supported	Not yet, per the developer docs
Max length per clip	30 seconds	30 seconds

The loop gap is the one practical catch. If you need a long room tone or rain bed that repeats without a seam, the developer docs still point you to v2 for looping. For everything with a clear start and end, v3 is the better pick.

How to Make AI Sound Effects with SFX v3

1. Lock your picture first. Generate sound against a final cut so you know exact durations.
2. Open the Sound Effects tab in ElevenCreative, or use Studio if you want effects on a timeline next to voice.
3. Write one beat per prompt. Describe the action, the surface, the space and the order of events.
4. Set the duration to match the shot, from a fraction of a second up to 30 seconds. Leave it automatic only when timing does not matter.
5. Adjust prompt influence. The default is 0.3. Raise it for literal, repeatable results; lower it when you want variations to choose from.
6. Generate a few takes and pick the best, the same way you would audition library sounds.
7. Download WAV where your plan allows it. ElevenLabs offers 48 kHz WAV for non looping effects, which drops cleanly into most video timelines.

Prompt Formulas That Work

ElevenLabs' own guidance lines up with how sound designers brief each other: be concrete, list events in the order they happen, and use real audio vocabulary such as impact, whoosh, ambience, one shot, drone or braam. Try these templates and swap in your own details:

• Sequence: "Slow footsteps on wet gravel, then a heavy metal gate creaks open, distant traffic in the background"
• Product ad hit: "Deep cinematic impact with a short reverse whoosh into it, clean, one shot"
• Location bed: "Busy Indian street market at dusk, vendors calling out, scooter horns, light crowd chatter"
• Transition: "Fast airy whoosh moving left to right, ending in a soft glitch"
• Music element: "Tight hip hop drum loop at 90 BPM, dry, no melody"

Two warnings from the docs: exact counts like "knock four times" are not always followed, and small wording changes can shift results a lot. If a prompt misses, rephrase it rather than regenerating the same words ten times.

What It Costs

ElevenLabs lists sound effects at 40 credits per second when you set a duration, so a 10 second effect is about 400 credits. Credits are shared with voice and other tools on your plan.

Plan	Price per month	Credits	Commercial license
Free	$0	10k	No
Starter	$6	30k	Yes
Creator	$22	121k	Yes
Pro	$99	600k	Yes

The free tier is fine for testing, but it does not include a commercial license, so anything for a client, an ad or a monetized channel belongs on a paid plan. Prices are from the ElevenLabs pricing page at the time of writing; Starter and Creator often run a discounted first month.

Bonus: Instant Soundtracks for Whole Videos

If you want sound for an entire cut rather than single effects, ElevenLabs also launched Instant Soundtracks in October. Upload a video to the music video editor in ElevenCreative and it composes an original score, spots moments that need effects, and drops them on the timeline at the right timestamps, like a whoosh on an end logo. Effects sit on their own layer, so you can retime or swap them before export. On the API, the same feature can return music and effects as separate files, with a limit of 10 videos and 10 minutes per request.

Treat it as a fast temp mix for short form and client drafts. For a hero film, I still prefer building the sound beat by beat so every effect is a choice.

Final Cut

ElevenLabs SFX v3 is not a revolution, but it is the update that makes AI foley usable for real scenes, because it finally follows a sequence of sounds the way a director describes it. Lock your picture, write one beat per prompt, layer generated sound under real location audio, and keep v2 around only for loops until v3 catches up. Your audience will never praise good sound design, but they will feel every frame of it.
