# MMaudio AI voice generation for turning videos into audio - Findings24: - Website: - Pricing: Freemium - Categories: AI Voice Generator ## What is MMaudio? MMaudio is an AI voice generation tool that focuses on video-to-audio generation. The home page presents it as a way to transform silent videos into audio by analyzing the video context and producing matched sound. The product interface supports uploading a file or using a video URL, then entering a prompt, an optional negative prompt, and a duration before generating audio. The pricing page shows both paid plans and a free plan with daily credits, so the service is structured around credit-based usage rather than unlimited generation. ## What can MMaudio do? ### Video input workflow Create audio from a video file or a video URL, which positions the product around turning existing visual content into sound. ### Prompt controls Guide generation with a text prompt and optional negative prompt, helping narrow the style or content of the output. ### Duration setting Adjust the target duration in seconds before generation, which gives users a basic timing control over the result. ### Advanced options Use the site’s advanced options area to work with additional generation settings, as shown on the home page. ### Credit-based usage Generate audio through a credit-based model, with the interface indicating one credit per model generation on the home page and plan-specific credit allotments on pricing. ### Plan-based upload limits Work with video upload constraints that are spelled out on the pricing page, including file-size limits and plan-dependent format support. ## Use Cases ### Add audio to short videos Turn a silent clip into generated audio by uploading the video, adding a prompt, and adjusting duration before processing. ### Process hosted videos Use the video URL option when the source content already lives online and you want to generate audio without downloading and re-uploading the file. ### Adjust generation intent Refine the output by pairing a prompt with a negative prompt and the advanced options area when you need more control over the result. ### Evaluate before upgrading Start with the free plan to evaluate the workflow, then move to a paid tier if you need more credits, larger uploads, or broader format support. ### Use in higher-volume workflows Choose a higher plan when working with larger files or when you need support for all video formats and API key management. ## Frequently Asked Questions ### How does MMaudio work?
