Silent videos are a thing of the past. Whether you’re creating social media content, producing indie films, or developing games, the gap between stunning visuals and matching audio has always been a creative bottleneck. Today, WaveSpeedAI is thrilled to announce the availability of HunyuanVideo-Foley—Tencent Hunyuan’s groundbreaking video-to-audio model that generates synchronized, high-fidelity Foley and ambient sound directly from your video content.
This isn’t just another audio generator. HunyuanVideo-Foley represents a fundamental leap in AI-powered sound design, achieving state-of-the-art performance across audio fidelity, visual-semantic alignment, and temporal synchronization benchmarks.
What is HunyuanVideo-Foley?
HunyuanVideo-Foley is an end-to-end Text-Video-to-Audio (TV2A) framework developed by Tencent’s Hunyuan research team. Unlike traditional audio generation tools that struggle with generalization and timing, this model analyzes the visual content of your video—identifying objects, actions, and environments—to automatically generate contextually appropriate sound effects that sync perfectly with on-screen movement.
The technology is built on a sophisticated multimodal diffusion transformer (MMDiT) architecture that processes both visual and text inputs simultaneously. This hybrid approach ensures that every footstep lands precisely when the foot touches ground, every glass shatters at the exact moment of impact, and ambient soundscapes match the mood of your scene.
Key Features and Capabilities
Exceptional Multi-Scene Synchronization
HunyuanVideo-Foley excels at handling complex, fast-cut visuals where traditional Foley generation falls apart. The model maintains precise audio-visual alignment across scene transitions, making it ideal for dynamic content like action sequences, montages, and music videos.
Professional-Grade 48kHz Audio Output
Quality matters. The model leverages a self-developed 48kHz audio VAE that produces broadcast-ready sound with minimal noise and artifacts. Whether you need crisp ASMR textures or dramatic ambient soundscapes, the output meets professional production standards.
Balanced Multimodal Response
Through innovative Representation Alignment (REPA) loss functions, HunyuanVideo-Foley balances visual cues with optional text prompts. This means you can let the AI interpret your video naturally, or guide it with specific descriptions like “rainy street ambience with distant thunder” or “kitchen ASMR with sizzling pan.”
State-of-the-Art Benchmark Performance
Comprehensive evaluations across the Kling-Audio-Eval, VGGSound-Test, and MovieGen-Audio-Bench datasets confirm that HunyuanVideo-Foley outperforms all open-source alternatives. The model achieves significant improvements in:
- Visual-semantic alignment (IB): The generated audio accurately reflects what’s happening on screen
- Temporal synchronization (DeSync): Sound events align precisely with visual actions
- Audio quality (PQ): Clean, professional output without artifacts
Trained on Massive Multimodal Data
With training on over 100,000 hours of multimodal data, HunyuanVideo-Foley generalizes remarkably well across diverse scenarios—from natural landscapes and urban environments to animated shorts and abstract visuals.
Real-World Use Cases
Film and Video Post-Production
Speed up your Foley workflow dramatically. Instead of recording or sourcing individual sound effects for each scene, generate a complete audio pass in seconds. Perfect for animatics, rough cuts, and indie productions where time and budget are constrained.
Social Media and Short-Form Content
Transform silent AI-generated videos into engaging content with perfectly synchronized sound. Whether you’re creating TikToks, Reels, or YouTube Shorts, consistent audio-visual timing keeps viewers watching.
ASMR and Atmospheric Content
The model’s sensitivity to subtle textures makes it exceptional for ASMR creators. Describe the sounds you want—gentle tapping, soft fabric rustling, delicate slicing—and watch the model deliver remarkably realistic audio tracks.
Game Development and Interactive Media
Quickly prototype audio for game sequences, generate placeholder Foley for development builds, or create final audio assets for indie games. The automated approach scales with your project’s needs.
Educational and Training Content
Demonstrate audio-visual alignment concepts, test sound design ideas rapidly, or add production value to instructional videos without extensive post-production resources.
Getting Started on WaveSpeedAI
Using HunyuanVideo-Foley on WaveSpeedAI is straightforward:
- Upload your video – Add the silent or low-sound clip you want to enhance
- Write a prompt (optional) – Describe the mood or specific sounds you want. Examples:
- “Busy café ambience, espresso machine, quiet conversations”
- “Forest atmosphere, birds chirping, wind through leaves”
- “Urban night scene, distant traffic, footsteps on wet pavement”
- Set your seed – Use a fixed number for reproducible results, or change it to explore variations
- Generate – Click Run and receive your audio-enhanced video within seconds
The model handles the complex work of analyzing motion, identifying objects, and synchronizing timing—you focus on the creative vision.
Why WaveSpeedAI?
Running advanced AI models locally requires significant GPU resources—HunyuanVideo-Foley alone demands 20GB of VRAM for optimal performance. WaveSpeedAI eliminates these barriers with:
- No cold starts – Your inference begins immediately, no waiting for model loading
- Fast inference – Optimized infrastructure delivers results quickly
- Affordable pricing – Pay only for what you use, no GPU rental commitments
- Production-ready API – Integrate directly into your existing workflows
The Future of Video Audio
HunyuanVideo-Foley represents a significant milestone in the convergence of visual and audio AI. As the AI video market accelerates toward a projected $2.56 billion by 2032, the demand for matching audio solutions will only grow. Content creators who master these tools today position themselves at the forefront of an evolving creative landscape.
Whether you’re a solo creator looking to enhance your content quality or a production team seeking to accelerate workflows, automated Foley generation is no longer a future promise—it’s available now.
