Feature Comparison
MMAudio
Context-Aware Audio Synthesis
MMAudio's AI doesn't just add random sounds; it intelligently analyzes your video frame-by-frame. It identifies elements like flowing water, crackling fire, or urban traffic and generates temporally consistent, on-beat sound effects that match the visual events. This deep learning analysis ensures the audio feels like a natural part of the scene, syncing perfectly with the on-screen action for a truly immersive result.
Text-Guided Sound Customization
For creative control, MMAudio allows you to guide the AI with text prompts. Describe the atmosphere you want, like "tense orchestral music with distant thunder" or "cheerful café chatter with light jazz." You can also use a negative prompt to exclude unwanted elements, such as "no voiceover" or "no guitar sounds." This feature lets you fine-tune the generated audio to fit your exact creative vision.
Fast, Web-Based Workflow
There's no software to download or install. The entire process happens online at MMAudio.me. You upload your MP4 video, set your preferences, and generate sound in moments. This streamlined, DAW-free workflow is designed for speed and accessibility, allowing you to iterate quickly and enhance videos without leaving your browser.
High-Fidelity Output for Professional Use
MMAudio is engineered to produce clean, high-quality audio suitable for professional projects. The generated soundtracks and effects are high-fidelity, avoiding the robotic or low-quality noise often associated with early AI audio tools. This makes the output ready for use in films, commercial content, animation, and other projects where audio quality is paramount.
Seedance 2
Multi-Modal Video Generation
Seedance 2 supports three distinct video generation modes: text-to-video, image-to-video, and video-to-video. This versatility allows users to create videos from scratch using text prompts, transform images into engaging video content, or re-style existing footage. The flexibility of these modes accommodates a wide range of creative needs, making it suitable for different projects and workflows.
Reference-First Control
This feature enables creators to anchor essential elements like character design, visual style, and camera feel using reference inputs rather than relying solely on text prompts. This approach significantly reduces guesswork, allowing for more precise and consistent video outputs that align closely with the creator's vision.
Joint Audio-Video Generation
Seedance 2 simplifies the video creation process by generating audio and video simultaneously in a single pass. This feature includes sound effects, background music, and voiceovers, ensuring that audio elements are perfectly synchronized with the visual content. This capability saves time and enhances the overall production quality.
High-Quality Output and Flexibility
With support for resolutions up to 1080p at 24 frames per second, Seedance 2 delivers high-definition video outputs that are suitable for professional use. Additionally, it supports various aspect ratios (16:9, 9:16, and 1:1), making it adaptable for different platforms and devices, whether for social media or traditional broadcasting.
Use Cases
MMAudio
Enhancing AI-Generated Videos
Platforms like Sora, LTX-Video, and Hunyuan create stunning visual clips, but they often lack synchronized audio. MMAudio is the perfect companion to these tools, analyzing the generated visuals to add realistic, context-appropriate soundscapes—turning silent AI videos into complete, immersive experiences instantly.
Social Media & Short-Form Content Creation
Content creators for TikTok, Instagram Reels, and YouTube Shorts can elevate their videos instantly. Upload a quick clip, describe a trendy or engaging sound vibe, and MMAudio generates a unique soundtrack or crisp sound effects in minutes, helping your content stand out in a crowded feed without copyright issues.
Indie Film & Animation Post-Production
For small film studios and independent animators, Foley work and sound design can be prohibitively expensive and time-consuming. MMAudio provides a powerful starting point, generating base ambient tracks and key sound effects that match the scene, which creators can then layer and refine, significantly speeding up the post-production pipeline.
Game Development & Asset Creation
Game developers can use MMAudio to quickly prototype sound for gameplay captures or cutscenes. By uploading video snippets of game environments (a forest, a spaceship interior, a battle), developers can generate fitting ambient audio and sound effects, streamlining the process of creating audio assets for dynamic in-game worlds.
