Full ambient soundscape
Veo 3.1 reads the environment in your prompt and generates layered ambient audio — ocean waves, city traffic, café chatter, forest birdsong — that persists through the clip and responds to what's on screen.
AI Video with Built-In Audio
AI video with audio means sound and picture are generated together from one prompt, instead of producing a silent clip and adding audio in post. Because both come from the same render, the result is frame-synced — a door slams exactly when it closes, footsteps land in step, music swells on the cut. This avoids the timing drift you get when a separate audio model is bolted onto silent video.
Features
What you can do
Sound effects tied to the action
Actions make sound at the exact frame they happen: a glass clinks as it lands, an engine Dopplers past, rain patters on a window. Generated contextually, not pulled from a stock library.
Dialogue with synced lips
Put a spoken line in your prompt and get a voice matched to the character. For dialogue-first shots, Kling 3.0 gives the most precise lip sync; Veo 3.1 blends speech into the wider mix.
Background music that fits the mood
Prompt a style — "gentle piano", "upbeat electronic", "tense orchestral" — and the model scores the scene, quieting under dialogue and building on action.
Mixed into one coherent track
Ambient, effects, dialogue, and music are balanced together at sensible relative volumes — a café scene layers espresso hiss, low chatter, clinking cups, and soft jazz, all at once.
Get started
How to use
1
Open the video generator with Veo 3.1
Go to PonPon Video and select Veo 3.1 for the richest soundscape, or Kling 3.0 when dialogue accuracy matters most.
2
Describe the audio in your prompt
Add sound detail: environment ("busy street"), specific sounds ("footsteps echo on marble"), dialogue ("she says: 'follow me'"), and music ("melancholy cello"). More audio detail yields a richer mix.
3
Or let the model fill it in
Even without audio cues, Veo 3.1 generates contextually appropriate sound — a forest gets birdsong and wind, a kitchen gets sizzling and clatter. Explicit prompting gives control; omitting it gives sensible defaults.
4
Generate and listen with sound on
Generate and review unmuted. Check that sounds line up with the action and dialogue matches the mouth. Regenerate if an element is missing or mistimed.
5
Download the finished audio-visual file
The download includes the embedded audio track — no separate export. To edit the audio out, import into any editor and split the track.
Showcase
Built for creators
Whether you're a solo creator, an agency, or a brand — every model adapts to how you work.
Café portrait with layered ambient sound
A woman sits at an outdoor café reading as the sun sets. Sound: espresso machine hissing inside, distant accordion music, light chatter, a bicycle bell passing on the street. No background music. 16:9, 8 seconds.
Rooftop scene with wind and music
A man stands on a city rooftop at golden hour, wind in his hair, looking over the skyline. Sound: steady wind across the roof, distant traffic hum below, a helicopter fading right. Soft ambient drone music. 16:9, 8 seconds.
Jazz club with live music ambience
Camera dollies through a dim jazz club toward the stage. Sound: a live saxophone playing a smoky blues melody, ice clinking in glasses, low conversation, a double bass underneath. No narration. 16:9, 8 seconds.
Who it's for
Use cases
Complete ad spots in one go
Produce 15-second ads with voiceover, music, and product sound effects from a single prompt — no voice actors, no music licensing, no audio post. Generate variations and A/B test the whole package.
Ambient and 'study with me' content
Create rich background loops — rain on glass, a crackling fireplace, distant thunder, soft jazz. The synced audio-visual loop is finished out of the box and performs well as long-form background video.
Scene prototyping with full sound
Test the mood and pacing of a scene with complete audio before any production. A tense hallway with echoing footsteps and low drone, or a market with vendor calls and guitar — evaluate the feeling, not just the frame.
Narrated explainers and essays
Turn script segments into clips where an AI narrator delivers the key point over fitting visuals and ambient sound. Chain clips in Flow for longer pieces.

FAQ
Questions & answers
Can AI generate video with sound?
How do I make an AI video with audio?
Open PonPon Video, pick Veo 3.1 or Kling 3.0, and describe the sound in your prompt alongside the visuals. Generate, listen with sound on, and download the clip with the audio embedded.
Which model is best for audio?
Can I control the sounds and music?
Yes. Describe specific sounds and a music style in your prompt ("rain on glass, distant thunder, soft piano"), or exclude them ("no music", "ambient only"). Without instructions, the model adds contextually appropriate audio by default.
Can I separate the audio from the video?
The download is an MP4 with audio embedded. To extract or replace the audio, import the file into any editor (iMovie, DaVinci Resolve, Premiere) or use FFmpeg. For standalone audio, see PonPon's audio tools.
Is AI video with audio free?
Yes. Free daily credits cover audio generation — it's part of every Veo 3.1 and Kling 3.0 render, not a separate add-on. See pricing for higher limits.
