## Overview

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.

## Pricing & Plans

Credit-based paid access. Each generation costs credits that depend on the chosen duration and model, and the cost is displayed before you run a job; consult the pricing page for current plans.

## Key Features & Capabilities

- **Video to audio synthesis:** Analyzes visual content and motion to produce sound effects that match what is happening on screen.
- **Prompt-guided sound design:** Describe the sounds you want in comma-separated keywords, plus a negative prompt to steer away from unwanted audio.
- **Environmental ambience:** Generates background ambience such as water, wind, crowds or machinery to make a scene feel real.
- **Model and duration controls:** Choose the generation model and clip length, with the credit cost shown before you run a job.
- **MCP and API access:** An MCP server listing lets agents and developer workflows call the audio generation service.

## Primary Use Cases

- **Add sound design fast (Video editor):** Generate ambience and effect layers for rough cuts so a scene has atmosphere before the final mix.
- **Make short clips feel finished (Social media creator):** Give vertical videos punchy, on-screen-matched sound without digging through stock libraries.
- **Rapid sound prototyping (Game developer):** Sketch placeholder effects and ambient beds for animation previews and prototypes.
- **Bring silent footage to life (Archivist or educator):** Add contextually plausible sound to historical or instructional video to keep viewers engaged.

## Strengths

- Turns silent video into finished-sounding audio in minutes
- Simple upload, prompt and generate flow with in-browser preview

- MCP support for developer and agent workflows

## Limitations

- Prompt guidance recommends English keywords, which narrows accessibility
