MMAudio is one of a growing group of "video-to-audio" models that turn silent footage into something that sounds finished. Rather than searching a sound library and manually aligning clips, you give the tool the video and a short description of the sounds you expect, and it generates audio that lines up with the on-screen motion. Example generations on the site include ice cracking under a blade, waves lapping a shore and a shovel scraping dry earth.

The web app is deliberately simple. You upload an MP4 (up to 50 MB) or paste a video URL, write a prompt in comma-separated English keywords, optionally add a negative prompt, pick how many seconds you need and choose a model. The interface shows the credit cost before you generate and plays the result in the browser once it is ready. A changelog and blog document ongoing model updates.

MMAudio is aimed at video editors, filmmakers, game developers, educators and social creators who need sound quickly. The site highlights use cases in film and video production, game development, archival film enhancement, educational content, storytelling and social media. Access is credit-based, with MCP support for agent and developer workflows.
