Native Video Audio
Generated on PixelDojo. Produced by PixelDojo's generation pipeline.
Most of them do. Of the 15 general purpose video models we checked on PixelDojo, 14 render a soundtrack in the same pass as the picture, and the fifteenth does it only on its image to video path. Native audio means the model generates sound and vision together, so dialogue, footsteps and room tone line up without any syncing step afterwards. Audio is on by default on nearly every model that has it. We read each model's audio capability, its default state and its toggle off the configuration files on August 26, 2026, and the model by model breakdown is below.
Which models make sound, and whether you can switch it off
VEO 3.1 Standard and Fast
Native audio, on by default, with a switch to turn it off. Both tiers declare audio support and both expose the toggle in the API and in the composer.
VEO 3.1 Lite
No audio generation at all. It is the only VEO tier without it, and that is part of why it is the cheapest of the three: 1.5 credits per second at 720p against 3 for Fast and 8 for Standard.
Kling Video
Audio on by default across all four combinations: Standard and Pro, text to video and image to video. Each variant exposes the toggle, and clips run 3 to 15 seconds.
Kling 2.6 Pro
Audio on by default with a toggle, on fixed 5 or 10 second clips.
WAN 3.0
A native audio track, on by default. It also takes up to 5 reference audio clips totalling 15 seconds to steer voice timbre for dialogue. Reference audio cannot be combined with first frame or last frame control in the same request.
Seedance 2.5
Native audio on by default, across 11 languages. It accepts up to 10 reference audio tracks totalling 30 seconds, tagged in the prompt as @Audio1 and so on, so you can point at the sound you want instead of only describing it.
Seedance 2 and Seedance 1.5
Both declare native audio and neither exposes an on or off switch. The soundtrack arrives with the clip.
WAN 2.7 Video
Native audio, and it is one of the few models that also accepts an audio URL as an input, so a clip can be generated against a track you already have.
WAN 2.6 Video
Declares native audio on both its text to video and image to video paths.
Flux 3 Video
Synchronized audio, on by default, with a toggle. It carries across text to video clips of up to 20 seconds and image to video.
Gemini Omni Flash
Native audio is always on and there is no way to disable it. The model is fixed at 720p and makes clips of 3 to 10 seconds.
MiniMax H3
Native synced audio. It also takes up to 3 reference audio clips, alongside reference images and reference videos, in the same request.
PixVerse V6
Audio is a toggle, and this is the only model in the catalog where switching it on changes the price. At 540p the rate goes from 1 to 2 credits per second. At 360p, 720p and 1080p the rate does not move.
Vidu Q3
Audio is supported but off by default. It is the clearest opt in of the set, so a clip generated with default settings comes back silent.
Grok Video
The text to video path has no audio. Switching to the Grok Imagine 1.5 backbone adds natively synchronized audio, but that backbone is image to video only, so it needs a starting frame to work from.
The avatar and performance tools
Kling Avatar, Kling Motion Control, Omnihuman and P-Video Avatar all declare audio too. These are performance tools built around a voice track rather than general purpose video models, so treat them as a separate category.
Read from each model's declared capabilities and input schema on August 26, 2026. Where a model has no audio switch we say whether that means always on or always off, rather than leaving it vague.
Why Choose Pixel Dojo for Native Video Audio
Professional-quality results with cutting-edge AI technology
Native audio is one pass, not two
The soundtrack is rendered with the picture in the same generation, so mouth movement, footsteps and room tone line up by construction. There is no separate sound job to run and nothing to align on a timeline afterwards.
On by default is the norm here
WAN 3.0, WAN 2.7 Video, Seedance 2.5, Kling Video, Kling 2.6 Pro, Flux 3 Video and VEO 3.1 Standard and Fast all arrive with audio enabled. Vidu Q3 is the one clear opt in, and Gemini Omni Flash has no switch at all.
Switching it off is the right call more often than people think
If the clip is going under a music bed or a recorded voiceover, generated ambience just fights it. Every model with a toggle lets you drop it, and on PixVerse V6 at 540p dropping it also halves the per second rate.
Several models take audio in as well as putting it out
WAN 3.0 accepts up to 5 reference clips for voice timbre, Seedance 2.5 up to 10 across 30 seconds, MiniMax H3 up to 3, and WAN 2.7 Video takes a plain audio URL as an input. That is how you get a consistent voice across several shots.
How It Works
How to get usable sound out of a video model:
Describe the sound in the prompt, not just the picture
These models read one prompt for both tracks. Naming the ambience, the dialogue line or the specific noise you want in the same sentence as the shot is what puts it in the render.
Leave the audio flag alone unless you have a reason
It is already on for nearly every model that supports it. Turn it off when you are laying your own music or voiceover underneath, because generated room tone will only compete with the mix.
Feed a reference clip when the voice has to match
For dialogue that carries across several shots, hand the model reference audio rather than re-describing the voice each time. WAN 3.0, Seedance 2.5, MiniMax H3 and WAN 2.7 Video all accept audio inputs for this.

Common Questions
Everything you need to know about Native Video Audio
Which AI video models generate audio natively?
VEO 3.1 Standard and Fast, Kling Video, Kling 2.6 Pro, WAN 3.0, WAN 2.7 Video, WAN 2.6 Video, Seedance 2.5, Seedance 2, Seedance 1.5, Flux 3 Video, Gemini Omni Flash, MiniMax H3, PixVerse V6 and Vidu Q3. Grok Video adds it only on its image to video backbone.
Is the generated audio actually in sync with the picture?
It is generated in the same pass rather than added afterwards, which is what the word native means here. Sound and vision come out of one model run, so there is no alignment step and no drift between the two tracks to correct.
Can I turn native audio off?
On most models, yes. VEO 3.1 Standard and Fast, Kling Video, Kling 2.6 Pro, WAN 3.0, Seedance 2.5, Flux 3 Video, PixVerse V6 and Vidu Q3 all expose an audio flag. Gemini Omni Flash has audio permanently on, and Seedance 2 and Seedance 1.5 have no switch either.
Does generating audio cost extra?
On one model. PixVerse V6 at 540p goes from 1 to 2 credits per second when audio is enabled. At its other three resolutions, and on every other model we checked, the credit rate is the same whether audio is on or off.
Can I give the model a voice or a track to work from?
Yes, on four of them. WAN 3.0 takes up to 5 reference audio clips totalling 15 seconds to set voice timbre. Seedance 2.5 takes up to 10 across 30 seconds and lets you refer to them in the prompt. MiniMax H3 takes up to 3. WAN 2.7 Video accepts an audio URL directly as an input.
Which video model produces no sound at all?
VEO 3.1 Lite. It is the only tier in the VEO family without audio generation, and it is also the cheapest, at 1.5 credits per second for 720p. Grok Video is silent too on plain text to video, though its image to video path does produce synchronized audio.
