AI Videos That Sound as Good as
They Look
Generate perfectly synchronized dialogue, sound effects, ambient audio, and music directly from your text prompts using Veo 3's revolutionary native audio engine. No post-production audio editing required.
How AI Audio Generation Works
Native audio generation that creates sound and visuals together — perfectly synchronized from the start
Describe Visuals & Sound Together
Write a single prompt that describes both your visual scene and the audio you want. For example: 'A barista making coffee in a sunlit café, the sound of espresso machines, gentle jazz in the background, steam hissing, cups clinking.' Veo 3 understands both dimensions from one description.
Veo 3 Generates Audio & Video Simultaneously
Unlike other AI video tools that generate silent clips requiring separate audio work, Veo 3 generates your video and its audio as a unified creation. Dialogue syncs naturally with mouth movements, sound effects are temporally aligned with on-screen actions, and ambient audio fills the scene organically.
Preview & Download with Full Audio
Your finished video plays back with complete, broadcast-quality audio — no mixing, no importing audio tracks, no post-sync work. Preview on CutFly, then download the video file with embedded audio ready to publish on any platform or drop directly into your creative workflow.
What Makes Veo 3 Audio Generation Unique
The only AI video generator with truly native audio — synchronized at the moment of creation
Native Audio — Not Added After
Veo 3 is the first major AI video model to generate audio as an integral part of the video creation process, not as a separate step. This means sound and image share the same creative DNA — mouth movements match speech, footsteps hit on visual cues, and environmental audio breathes life into every frame.
Full Audio Spectrum Support
Generate any type of audio your scene requires: natural dialogue and voiceover, foley sound effects (footsteps, impacts, objects), ambient environmental sounds (rain, wind, crowd noise), musical scores and background music, and even complex soundscapes layering multiple audio elements simultaneously.
Intelligent Audio-Visual Synchronization
The AI doesn't just generate audio alongside video — it generates audio that is causally linked to the visuals. When a door slams on screen, the sound hits at that exact frame. When a character speaks, their lips form the words naturally. This causal synchronization is only possible because audio and video are generated together.
Zero Post-Production Required
Traditional video production requires a separate audio workflow: recording, editing, mixing, syncing to picture, mastering, and exporting. With Veo 3 audio generation, this entire workflow collapses to zero. Your final video with complete audio is ready in the same time it takes to generate the visuals alone.
Native Audio AI vs Traditional Audio Post-Production
How Veo 3's integrated audio changes the video production equation
Traditional Audio Post-Production
- Record or source audio separately from video production
- Time-consuming manual sync of audio to visual cues in editing software
- Requires audio editing skills, DAW software, and sound library subscriptions
- Separate mastering and mixdown process before final export
Veo 3 Native Audio via CutFly
- Describe audio and visuals in one prompt — generated simultaneously
- Audio is causally synchronized to video — no manual sync needed
- No audio skills, software, or sound library required
- One download — complete video with broadcast-ready audio embedded
What You Can Create with AI Audio
From social shorts to documentary-style content — native audio elevates every format
Dialogue-Driven Story Videos
Generate videos where characters actually speak — AI creates natural dialogue synchronized to mouth movements. Tell stories with conversations, interviews, and monologues without hiring actors, recording voice, or syncing audio in post. The characters' words and expressions emerge as one coherent performance.
Immersive Documentary Content
Create documentary-style videos where the ambient soundscape brings every location to life. Generate nature documentaries with authentic animal sounds and wind, urban scenes with traffic and crowd energy, or industrial settings with authentic mechanical atmospheres — all from text descriptions.
Product & Brand Videos with Ambient Sound
Elevate product demonstrations with rich ambient audio that sets the perfect mood. A coffee brand video with café ambiance, a technology product with a clean futuristic soundscape, a fashion brand with runway music — native audio makes your brand content feel premium and fully produced.
Educational & Explainer Content
Produce educational videos where narration, sound effects, and visual demonstrations are perfectly integrated. Science explainers with authentic lab sounds, history lessons with period-appropriate ambient audio, or technology tutorials with interface click sounds — all generated cohesively from your prompt.
